KYA 3.4×38mm wire collated concrete nails are carbon steel fasteners designed for fastening into suitable concrete, masonry and stone substrates with compatible concrete fastening equipment. Product code KYA-3.4x38mm uses a nominal 3.4mm diameter and 38mm length.
The nail is manufactured from 45# carbon steel and uses a compact, rigid shank profile suitable for direct fastening applications where the nail dimensions, substrate and installation tool are correctly matched. KYA lists multiple shank and surface treatment options within the broader concrete nail range.
Because collated concrete nail systems differ between manufacturers, buyers should confirm the exact nailer model, magazine type, collation format, accepted nail diameter and length before ordering.

Wire collation keeps multiple concrete nails aligned for feeding through compatible fastening equipment. The exact magazine and collation requirements depend on the concrete nailer being used, so the fastener should be matched to the tool rather than selected only by nail length.
The nail is manufactured from 45# carbon steel, a medium-carbon steel grade commonly used where greater hardness and strength than low-carbon steel are required. Concrete nail performance also depends on heat treatment, nail geometry, substrate condition and installation method.
The exact product shown on this page has a nominal diameter of 3.4mm and a nominal length of 38mm. These dimensions should be checked against the tool specification and required penetration before use.
The diamond point provides a defined penetrating tip for direct fastening into suitable mineral substrates. Base-material hardness and density affect installation performance.
KYA describes this concrete nail family with a flat and countersunk-style head profile. Head geometry should match the component being attached and the nose configuration of the installation tool.
KYA currently lists galvanized, mechanical galvanized, hot-dip galvanized and phosphated steel options within the product range. Availability should be confirmed for the exact size, shank and collation required.
Concrete nails are used for direct fastening into suitable concrete, masonry and stone substrates. The correct nail and installation tool should be selected according to the base material, component thickness and required penetration.
Fastening into concrete walls
Masonry fastening
Stone and mineral substrate fastening
Wood strips or light components to suitable concrete or masonry
Construction and renovation fastening
Temporary construction work where this nail specification is suitable
Light building components installed with compatible direct-fastening equipment
Do not assume that one concrete nail is suitable for every concrete grade, masonry unit or attachment. Very hard concrete, brittle masonry and thin substrates can require a different fastener system.
The current KYA product family lists multiple nominal nail lengths. The exact available combination of diameter, shank, finish and collation should be confirmed before ordering.
| Listed Length | Approx. Inch Size |
|---|---|
| 19mm | 3/4" |
| 25mm | 1" |
| 28mm | 1-1/8" |
| 32mm | 1-1/4" |
| 38mm | 1-1/2" – Product shown on this page |

| 100mm | 4" |
The exact product code on this page is KYA-3.4x38mm. For replacement purchasing, use the specific product dimensions rather than only the general concrete nail category.
KYA currently lists straight, twisted and smooth shank configurations within this concrete nail product family. Different shank geometries are intended for different fastening requirements and should be selected together with the correct nail diameter and length.
| Shank Type | Selection Consideration |
|---|---|
| Smooth Shank | Straight surface for applications specifying a conventional smooth concrete nail. |
| Straight Shank | Select according to the exact KYA configuration and installation equipment. |
| Twisted Shank | Available within the product family where this shank geometry is specified. |
Holding performance should not be estimated from shank style alone. Base material, embedment depth, nail hardness, tool energy and installation quality all affect the final fastening result.
| Finish | Description |
|---|---|
| Galvanized | Zinc-coated steel finish offered within the KYA concrete nail range. |
| Mechanical Galvanized | Mechanically applied zinc coating option listed for the product family. |
| Hot-Dip Galvanized | Hot-dip zinc coating option available within selected configurations. |
| Phosphated Steel | Phosphated surface option listed within the current KYA product range. |
Finish selection should be based on the installation environment and project specification. A galvanized finish should not automatically be treated as suitable for every outdoor, marine or chemically aggressive environment.
Collated concrete nail systems are tool-specific. Different nailer manufacturers use different magazines, strips, pin dimensions, head geometries and fastening-energy systems.
Some professional concrete nailers use plastic-collated pins, while others use proprietary strips or magazines. A nail should therefore not be considered compatible with a gas, battery or pneumatic concrete nailer simply because the nail length is similar.
| Product | KYA-3.4x38mm |
| Nominal Diameter | 3.4mm |
| Nominal Length | 38mm |
| Collation | Wire Collated |
| Base Material | Concrete / Masonry / Stone, subject to tool and substrate requirements |
| Required Tool | Concrete fastening equipment designed to accept the complete KYA fastener dimensions and collation format |
| Before Ordering | Provide the exact nailer manufacturer, model, magazine type and currently used fastener specification |
Do not assume direct compatibility with Hilti, Bosch, MAX, Rawlplug or other concrete nailers unless the exact tool specifications match this nail configuration.
Concrete nail selection should begin with the installation tool and base material. After confirming the nailer format, choose the nail diameter and length according to the component being fastened and the required embedment.
A longer or thicker nail is not automatically the correct choice. Excessive nail length or tool energy can damage brittle masonry, while insufficient embedment can reduce fastening performance.
When replacing an existing collated concrete nail, provide the old nail dimensions, head shape, strip or collation format and tool model. This is more reliable than matching only the stated nail length.
For accurate product matching and quotation, provide the required nail size, shank type, surface treatment, purchasing quantity, installation tool manufacturer and model, substrate and delivery destination.
For the exact product shown on this page, reference KYA-3.4x38mm and specify 3.4mm diameter × 38mm length, 45# carbon steel, wire collated concrete nail.

The exact KYA product is model 3.4×38mm, product code KYA-3.4x38mm, with a nominal 3.4mm diameter and 38mm length.
KYA specifies 45# carbon steel for this concrete nail product.
45# steel is generally classified as a medium-carbon steel grade. It contains approximately 0.45% carbon and is commonly used where higher hardness and strength than low-carbon steel are required.
Concrete nails are used for suitable concrete, masonry and stone substrates. Actual suitability depends on substrate hardness, thickness, fastener size and the installation equipment.
KYA describes the concrete nail family with a diamond point.
The current KYA product page lists galvanized, mechanical galvanized, hot-dip galvanized and phosphated steel finish options.
KYA currently lists straight, twisted and smooth shank options within this concrete nail product family.
Compatibility cannot be confirmed from the brand name alone. Hilti uses tool-specific collated fastener systems, so the exact Hilti model, magazine and accepted fastener dimensions must be checked against the KYA nail specification.
Only if the specific tool accepts the same nail dimensions, head geometry and wire-collated format. Different concrete nailers often use different proprietary magazines and collations.
Do not assume so. Professional direct-fastening systems often use different fasteners for concrete and steel. Confirm the substrate and tool manufacturer's approved fastener specification before use.
Select the nail length according to the thickness of the component being attached, required embedment, substrate condition and the accepted fastener range of the installation tool.
Provide the required nail dimensions, shank style, finish, purchasing quantity, concrete nailer manufacturer and model, base material and delivery destination. Reference KYA-3.4x38mm for the product shown on this page.
