When your crew is moving fast on a concrete or steel substrate, you need a fastener that keeps up without cutting corners. The NK32 drive pin is engineered for exactly that — delivering reliable penetration and secure holding power across the demanding conditions of real job sites.
Manufactured from high-grade steel with a smooth shank and zinc-plated finish, the NK32 drive pin resists corrosion and maintains structural integrity even in humid or chemically active environments. The integrated metal washer distributes load evenly across the fastening surface, reducing the risk of material cracking and ensuring a clean, flush result every time.
Shank Type: Smooth
The smooth shank enables clean, consistent penetration into hard substrates — minimizing resistance during drive and reducing the risk of material cracking, which is especially important when working with concrete slabs or steel decking.
Shank Diameter: 3.7 mm
Sized to fit standard powder-actuated tool barrels, the 3.7 mm shank delivers a tight, stable hold without over-stressing the base material.
Head Diameter: 6.0 mm
The 6.0 mm head works in combination with the metal washer to distribute load evenly across the fastened material's surface — preventing pull-through on thinner steel channels, furring strips, or track sections.
Metal Washer: Included
Unlike plastic-washer pins, the NK32 drive pin comes with a metal washer that provides superior clamping strength and long-term corrosion resistance — suited for exposed or semi-exposed environments such as shipbuilding, power generation facilities, and mine structures.
Material: Steel
High-carbon steel construction ensures the NK32 drive pin withstands the impact forces generated by powder-actuated tools without deformation or premature tip blunting.
Finish: Zinc Plated
The zinc plating offers a protective layer against rust and oxidation, extending the service life of the fastener in humid or outdoor construction environments.
Packing: Box + Carton + Pallets
Each box is packed for easy on-site handling and bulk shipment, with pallet-ready carton configuration to streamline warehouse receiving and logistics for large orders.
MOQ: 5,000 Boxes
Available in bulk quantities to support contractors, distributors, and procurement teams sourcing at scale. OEM labeling and custom packaging are available upon request.

The NK32 drive pin is a concrete nail designed for use with powder-actuated tools, and the integrated metal washer is not simply an add-on — it is a functional part of the design. The washer distributes the clamping load across a wider surface area, reducing the risk of pull-through when fastening thin materials such as steel tracks, sheet metal brackets, or strapping over concrete and steel substrates.
Without a washer, a standard pin concentrates stress at a single point. Under vibration or dynamic load — common in construction environments — this can cause fastened materials to work loose over time. The metal washer on the NK32 eliminates this risk, making it the preferred choice for applications where long-term holding performance matters.

The zinc plating protects the shank and head from oxidation during storage and after installation, which is particularly important in humid environments such as coastal construction sites or covered industrial facilities.
The NK32 is designed for use with standard powder-actuated fastening tools operating on .22 caliber loads. It is compatible with most leading tool platforms on the market, including tools compliant with CE and ANSI safety standards. If you are unsure whether the NK32 is compatible with your existing equipment, our team is happy to confirm compatibility before you place an order.
Structural steel to concrete connections — Attaching steel plates, base tracks, or angle brackets directly to concrete floors and walls is one of the most common uses. The smooth shank allows clean, consistent penetration, while the metal washer ensures the bracket is held firmly without surface damage.
Electrical conduit and cable management — In commercial and industrial electrical work, drive pins are used to anchor conduit clamps and cable trays to structural concrete. The NK32's dimensions make it a reliable choice for this type of repetitive, precision installation.
Steel deck and floor panel fastening — In building construction and shipbuilding, steel decking panels are frequently secured using drive pins rather than welding, saving both time and equipment cost on site.
MEP installation — Mechanical, electrical, and plumbing contractors routinely use drive pins for hanging strapping, brackets, and support channels from concrete overhead structures. The NK32 offers consistent penetration depth and holding strength across these installations.
Industrial and mining environments — In facilities where permanent structural fastening is needed and access to welding equipment is limited, drive pins provide a practical, code-compliant alternative.
Consistent hardness throughout the shank. Our NK32 pins are manufactured from high-carbon steel with controlled heat treatment, ensuring hardness is uniform along the full length of the shank — not just at the tip. Inconsistent hardness is a common cause of pin deflection or breakage on harder substrates. Our production process eliminates this variable.
Precision dimensional tolerances. The shank diameter of 3.7 mm is held to tight tolerances across every batch. This matters because powder-actuated tools are sensitive to pin diameter — pins that are even slightly out of specification can cause misfires, tool jams, or inconsistent drive depth.
Zinc plating for extended shelf life. Our plating process meets standard corrosion resistance requirements, giving the pins a usable shelf life suited to bulk purchasing and warehousing — an important consideration for distributors and contractors buying at volume.
Batch-consistent quality. Each production batch is subject to internal quality checks covering dimensional accuracy, surface finish, and mechanical hardness. We supply test reports on request, which is something many clients find valuable when qualifying a new fastener supplier.
OEM labeling is available — if you supply your own brand for the fastener market, we can produce the NK32 under your label with customized box printing and documentation.
Standard production lead time is confirmed at the time of order, depending on current production scheduling. We recommend contacting us early if you have a project deadline, so we can plan accordingly.
Can the NK32 be used on steel substrates as well as concrete?
Yes. The NK32 performs well on both concrete and structural steel, which is why it is widely used in steel-framed construction and shipbuilding. The appropriate powder load strength will vary by substrate — your tool manufacturer's load selection chart will guide this.
What is the effective embedment depth in standard concrete?
At appropriate load levels, the NK32 typically achieves 20–25 mm of embedment in normal-weight concrete (25–40 MPa). Actual penetration will vary based on concrete hardness, load strength, and tool type.
Is the zinc plating sufficient for outdoor use?
The zinc plating provides basic corrosion resistance suitable for sheltered and semi-exposed environments. For long-term outdoor exposure without cover, we recommend discussing coating options with our team.
Do you supply test or quality documentation?
Yes. We can provide dimensional inspection reports and material certificates on request for qualified orders.
