KYA HT50 14 gauge concrete T-nails are hardened straight-strip fasteners measuring 50 mm / 2 inches long. The current KYA specification uses an approximately 2.1 mm shank diameter and a T-shaped head for compatible 14GA pneumatic concrete nailers.
The 50 mm length is suited to professional fastening applications where the nail must pass through thicker wood, plywood, furring strips, light-gauge track or similar materials before achieving suitable penetration into concrete, masonry or another compatible substrate.
50 mm / 2" length: designed for applications requiring greater reach through the attached material.
14 gauge T-nail platform: approximately 2.1 mm shank diameter for compatible pneumatic concrete T-nailers.
T-shaped head: provides a wider bearing area than narrow-head concrete finish nails.
Hardened carbon steel: manufactured for driving into suitable concrete, masonry and other dense substrates.
Galvanized finish: provides corrosion protection for suitable indoor and protected applications.
0° straight-strip collation: glue-collated for compatible ST64-class concrete nailers.
40 nails per strip: current KYA concrete T-nail strip configuration.
1,000 nails per box: commercial packaging for distributors, contractors and professional users.

A 50 mm concrete T-nail provides additional length for installations where the fastener must pass through a relatively thick wood, plywood, furring or light-gauge component before reaching the concrete or masonry substrate.
Longer is not automatically better. The nail still needs to achieve suitable embedment without creating unnecessary driving resistance. For thinner materials, a shorter 25 mm, 32 mm or 38 mm concrete T-nail may be more appropriate.
HT50 concrete T-nails are manufactured from hardened carbon steel for use in suitable dense substrates. Hardening provides the rigidity required to withstand the driving forces generated by pneumatic concrete nailers.
Concrete fastening performance depends on more than nail hardness. Concrete strength, aggregate, substrate thickness, edge distance, nail length and nailer energy all affect whether a nail can be driven and seated correctly.
For very dense or brittle substrates, perform test fastenings before repetitive installation rather than assuming that a longer hardened nail will penetrate every concrete mix.
The KYA concrete T-nail platform uses an approximately 2.07–2.1 mm shank with an approximately 5.9–6.1 mm wide T-shaped head. The wider head provides bearing area against the attached material.
Industry ST64-class systems can publish slightly different nominal dimensions, such as approximately 2.2 mm shanks and wider heads. When replacing another manufacturer's nails, compare the full fastener geometry and test magazine fit rather than relying only on the 14GA designation.
HT50 nails are supplied as straight glue-collated strips for feeding through compatible pneumatic concrete T-nailers. The current KYA packing configuration uses 40 nails per strip.
Reliable feeding depends on nail-head dimensions, shank diameter, strip pitch, adhesive condition and magazine geometry. A fastener should not be considered universally compatible simply because another tool is also described as a 14GA concrete nailer.
The featured HT50 configuration uses a galvanized steel surface. The zinc coating provides corrosion protection compared with uncoated hardened carbon steel and is suitable for appropriate indoor and protected construction environments.
Do not assume that a standard galvanized concrete nail is automatically suitable for continuous exterior moisture, coastal exposure, chemically aggressive environments or every preservative-treated material. Match the fastener finish to the actual service conditions.
Furring strips: fastening thicker timber strips to suitable concrete or masonry substrates.
Plywood to concrete: selected non-structural plywood attachment where 50 mm provides suitable reach and embedment.
Wood to concrete: selected timber components where direct pneumatic fastening is appropriate.
Light-gauge track: selected drywall runner and metal-track fastening to suitable concrete floors or walls.
Wire lath: selected lath fastening applications where the project permits this T-nail system.
Steel banding: selected attachment work using compatible substrates and nailer systems.
Renovation and interior construction: repetitive professional fastening where a longer 14GA concrete T-nail is appropriate.
The 50 mm length is useful when the furring strip or other attached wood component is thick enough that shorter concrete nails would not provide the desired substrate penetration.
The correct length depends on the furring-strip thickness and concrete density. Very hard concrete may drive more reliably with a shorter fastener if the required embedment can still be achieved.
HT50 can be used for selected plywood and wood-to-concrete fastening applications where the 50 mm length allows the nail to pass through the wood and achieve suitable penetration into the receiving substrate.
For structural sheathing, load-rated framing, engineered wood connections or other assemblies with specified design loads, use the fastening or anchoring system required by the project documentation.
Concrete T-nail systems are used for selected drywall runner, light-gauge track and similar attachment work to concrete floors or walls.
Because light-gauge track itself is thin, a full 50 mm nail is not necessary for every installation. Select the nail length according to the attached materials and the required substrate penetration rather than automatically choosing the longest fastener.
Concrete T-nails can be used in flooring-related fastening, but 50 mm / 2" is considerably longer than normally required for many thin carpet tack-strip installations.
For thin tack strips, compare shorter 18 mm, 25 mm or other suitable lengths according to strip thickness, substrate and tool requirements. HT50 is better positioned for applications involving thicker attached materials.
Concrete is not a uniform material. Aggregate type, age, compressive strength, substrate thickness and edge distance can all change fastening performance.
Perform test fastenings in the actual substrate before repetitive installation. If the HT50 bends, fails to seat fully or causes excessive cracking or spalling, use an alternative nail length, tool setting or fastening method.
HT50 belongs to the common 14GA straight-strip concrete T-nail class. Several professional pneumatic nailers publish fastener ranges that include 50 mm T-nails.
| Tool Platform | Published Fastener Range | Matching Guidance |
|---|---|---|
| KYA ST64 | 14GA concrete T-nails, approximately 18–64 mm; tool specification lists approximately 2.2 mm shank. | 50 mm is within the tool's published length range. Confirm current production head and strip dimensions. |
| WOODPECKER ST64 | 14GA concrete T-nails from approximately 18–64 mm. | 50 mm is within the advertised length range. Verify shank, head and strip dimensions before bulk use. |
| KAMSIN ST64 | 14GA T-nails approximately 18–64 mm with published shank around 2.2 mm. | Same general ST concrete T-nail platform; dimensional verification is recommended before substitution. |
| AIR LOCKER CN64A3 | 14GA T-nails approximately 5/8"–2-1/2", published diameter around .087". | 50 mm falls within the published length range. Confirm exact collation and head dimensions. |
The KYA ST64 pneumatic concrete T-nailer is designed for 14GA concrete T-nails from approximately 18 mm to 64 mm. Its published tool specification lists an approximately 2.2 mm nail shank and a 100-nail magazine.
HT50's 50 mm length is therefore within the ST64 tool's published length range. Because the nail page and tool page publish slightly different nominal shank and head dimensions, confirm current production fit before high-volume use.
WOODPECKER ST64 is marketed for 14GA concrete T-nails from approximately 18 mm / 3/4" through 64 mm / 2-1/2", including a 50 mm / 2" fastener option.
This makes it a useful market reference for HT50. Cross-brand use should still be checked using the actual fastener dimensions and magazine geometry.
KAMSIN publishes a 14GA concrete T-nail range from approximately 18 mm through 64 mm and includes a 50 mm ST50 version. Its current published fastener uses approximately a 2.2 mm shank and 6.7 mm head.
These dimensions are close to the KYA concrete T-nail platform but are not identical to every dimension shown on KYA's product pages. Verify physical fit rather than treating the brand names as proof of universal interchangeability.
Published data for the AIR LOCKER CN64A3 lists 14GA T-nails approximately 5/8" to 2-1/2" long with a nominal diameter around .087". The 2" HT50 length falls within that published range.
Before bulk use, verify head profile, strip spacing and magazine fit using the actual CN64A3 tool.
KYA identifies this product page as HT50. In the broader concrete T-nail market, the 50 mm / 2" fastener in this general 14GA platform is commonly described as ST50.
When cross-referencing HT50 against an ST50 or ST64 nailer system, compare the actual shank diameter, head width, head thickness, strip spacing and collation rather than relying only on the model name.
| Characteristic | HT50 Concrete T-Nail | FST50 Concrete Finish Nail |
|---|---|---|
| Gauge | 14GA | 15GA |
| Length | 50 mm / 2" | 50 mm / 2" |
| Shank | Approximately 2.1 mm | Approximately 1.8 mm |
| Head | Wide T-shaped head | Narrow approximately 2.8 mm head |
| Tool Platform | 14GA ST64-class concrete T-nailer | 15GA FST concrete finish nailer |
| Directly Interchangeable | No | No |
The current KYA HT50 configuration contains 40 nails per glue-collated strip and 1,000 nails per box.
Packing quantity can differ between manufacturers even when the fasteners belong to the same general ST50 dimensional class. KAMSIN, for example, currently sells similar 14GA ST50 nails in an 800-piece box, so box quantity is not an indicator of tool compatibility.

HT50 is a 14 gauge concrete T-nail measuring 50 mm / 2 inches long with an approximately 2.1 mm shank diameter.
HT50 belongs to the same general 14GA 50 mm concrete T-nail class commonly described as ST50 in the market. Exact shank, head and strip dimensions should still be compared before cross-brand substitution.
Typical applications include thicker furring strips, selected plywood and wood-to-concrete fastening, light-gauge track, wire lath and other professional installations where a 50 mm concrete T-nail is appropriate.
A 50 mm nail is longer than required for many thin carpet tack-strip installations. Shorter concrete T-nails are often more appropriate. Select the nail length according to tack-strip thickness and substrate.
Yes, when the 50 mm length provides suitable penetration through the furring strip and into a compatible concrete or masonry substrate.
It can be used for selected non-structural plywood-to-concrete installations where the nail dimensions, substrate and required embedment are appropriate.
Concrete T-nails are used for selected light-gauge track applications, but 50 mm is not necessary for every installation. Choose the length according to the attached materials and required substrate penetration.
Do not treat HT50 as a universal structural anchor. Load-rated framing and engineered connections can require fastening systems with documented capacities and installation requirements.
Performance depends on concrete strength, aggregate, age, nail length and nailer driving energy. Test the actual substrate before repetitive installation instead of assuming one hardened nail will penetrate every concrete mix.
The KYA ST64 publishes a 14GA concrete T-nail length range of approximately 18–64 mm, so 50 mm is within its stated range. Confirm current production head and shank dimensions before volume use.
WOODPECKER ST64 is marketed for 14GA concrete T-nails from 18 mm to 64 mm, including 50 mm fasteners. Verify complete dimensions and strip fit when using third-party nails.
KAMSIN ST64 uses the same general 14GA 18–64 mm concrete T-nail class. KAMSIN publishes slightly different nominal shank and head dimensions, so confirm physical fit before bulk use.
Published CN64A3 data lists 14GA T-nails from approximately 5/8" to 2-1/2", so the 2" length falls within its range. Confirm strip, head and shank geometry before production use.
No. Different tools can specify different head widths, shank diameters and strip geometry. Match the full fastener specification to the tool rather than relying on gauge alone.
HT50 is a 14GA concrete T-nail with an approximately 2.1 mm shank and wide T-shaped head. FST50 is a thinner 15GA hardened concrete finish nail with an approximately 1.8 mm shank and much narrower head. Their tool systems are different.
