KYA 15 Gauge FST35 Hardened Steel Concrete Nails are straight-strip fasteners designed for professional fastening into suitable concrete, masonry and other hard substrates with compatible 15 gauge concrete nailers.
The FST35 measures 35mm / 1-3/8 inch in length with a nominal 1.8mm / .071 inch shank diameter and approximately 2.8mm head width. The nails are manufactured from hardened high-carbon steel and supplied with a galvanized finish for corrosion protection in suitable construction and interior fastening applications.
Each straight strip contains 50 nails, with 1,500 nails per box. Typical applications include furring strips, drywall track, light-gauge framing components, skirting, trim, wood-to-concrete fastening and selected renovation work where the substrate and nailer are suitable for FST-series concrete nails.

Request FST35 PricingFST concrete nails are manufactured from hardened high-carbon steel to provide the hardness and toughness required for fastening into suitable dense substrates. The actual ability to drive the nail depends on concrete hardness, aggregate, substrate condition, nail length and nailer power.
The FST35 is a mid-range length within the KYA FST family. It can be used where a 35mm nail provides suitable penetration through the attached material and into the receiving concrete or masonry substrate.
The approximately 1.8mm shank diameter provides the standard profile used across the KYA 15GA FST Series and should be matched to a nailer designed for this fastener family.
The nails are assembled into straight strips for repeated feeding through compatible pneumatic or powered concrete finish nailers. Each strip contains 50 fasteners.
The galvanized surface provides basic corrosion protection compared with untreated carbon steel. For permanently wet, coastal, chemically aggressive or other high-corrosion environments, confirm the required material and coating before use.
FST35 nails can be used for fastening suitable wood furring strips to concrete or masonry where the strip thickness, concrete condition and required penetration are appropriate for a 35mm fastener.
Straight-strip concrete nails are commonly used to fasten selected drywall track, runners and light-gauge components to concrete floors or walls with compatible tooling.
FST nails can be used for selected skirting, baseboard and interior trim fastening where a hardened 15GA concrete nail is specified for the substrate.
Wood components can be fastened to suitable concrete using FST35 nails where the material thickness and required embedment correspond to the 35mm nail length.
Commercial renovation and interior construction work can use FST-series nails for compatible fastening tasks involving trim, framing accessories, tracks and other non-structural components.
The KYA FST Series includes multiple lengths from 18mm to 50mm. The correct length should be selected according to the thickness of the material being attached, required penetration and concrete condition.

| Selection Factor | What to Check |
|---|---|
| Attached Material Thickness | Measure the wood, track, trim or other component being fixed |
| Required Embedment | Select enough penetration into the receiving substrate without excessive depth |
| Concrete Hardness | Hardness and aggregate can affect driving performance and suitable nail length |
| Edge Distance | Avoid fastening too close to concrete or masonry edges where cracking may occur |
| Nailer Capacity | Confirm the tool accepts the selected FST length |
FST concrete nails and conventional woodworking finish nails may both use a 15-gauge description, but they are designed for different substrates and tools.
| Feature | 15GA FST Concrete Nail | 15GA Wood Finish Nail |
|---|---|---|
| Primary Substrate | Suitable concrete, masonry and hard fastening substrates | Wood and wood-based materials |
| Material | Hardened high-carbon steel | Finish-nail steel specification |
| Collation | Straight FST strip | Straight or angled depending on nail family |
| Tool | Dedicated concrete / FST nailer | Wood finish nailer |
| Interchangeable? | No. Use only the fastener type specified for the tool and substrate. | |
FST35 is intended for compatible 15 gauge concrete finish nailers. KYA references Tacwise EHS50V and Spotnails LT50 tool families; confirm the exact nailer model, accepted FST profile and 35mm fastener range before ordering.
| Compatibility Factor | FST35 Requirement |
|---|---|
| Gauge | 15 Gauge |
| Shank Diameter | 1.8mm / .071 in. |
| Length | 35mm / 1-3/8 in. |
| Collation | Straight Glue-Collated Strip |
| Strip Capacity | 50 nails per strip |
| Tool Specification | Must explicitly accept FST-style concrete nails and 35mm length |
Concrete density, age, aggregate and surface condition vary significantly. Perform a test fastening before repetitive installation to confirm that the nail drives correctly without bending, breaking or damaging the substrate.
Choose a nail long enough to pass through the attached material and achieve suitable embedment, but avoid unnecessary extra length that may make driving more difficult in dense concrete.
Driving hardened nails too close to an edge can increase the risk of concrete or masonry cracking. Follow the project fastening requirements and tool manufacturer's instructions.
FST nails require a compatible concrete nailer with sufficient driving energy and the correct magazine geometry. A standard woodworking finish nailer should not be used unless the tool manufacturer specifically approves FST concrete nails.

FST35 is 35mm / 1-3/8 inch long with a nominal 1.8mm / .071 inch shank diameter.
Each strip contains 50 nails.
The KYA packing specification lists 1,500 nails per box.
Typical uses include furring strips, drywall track, skirting, trim, selected light-gauge metal components and wood-to-concrete fastening.
Yes. KYA lists FST concrete nails as hardened high-carbon steel fasteners designed for use in suitable dense substrates.
Yes. FST35 uses a galvanized finish.
Performance depends on concrete hardness, aggregate, nailer driving power, fastener length and installation conditions. Test the substrate before production use rather than assuming one concrete nail will penetrate every concrete mix.
Use a 15 gauge FST or concrete finish nailer that explicitly accepts a 1.8mm shank and 35mm nail length. KYA references Tacwise EHS50V and Spotnails LT50 tool families, but exact model compatibility should be verified before use.
No. Standard woodworking finish nailers and dedicated concrete FST nailers are different tool systems. Use only a tool whose manufacturer specifies compatibility with FST-style concrete nails.
The KYA FST Series includes 18, 20, 25, 30, 32, 35, 40, 45 and 50mm lengths.
Choose according to the thickness of the material being attached, required embedment, concrete hardness and the fastener lengths accepted by the nailer. Longer nails are not automatically better for harder concrete.
Yes, selected drywall track and light-gauge fastening applications are common uses for FST concrete nails when the track, substrate and nailer are compatible.
Contact KYA Fasteners to confirm sample availability. For distributor or contractor evaluation, test the nails with the actual nailer and substrate before bulk purchasing.
