ULTRA-RIGID STRUCTURAL BONDING ā€“ Premium 1-3/8 Inch Knurled Steel Collated Nails for Fastening Wood to Concrete

Establish a rock-solid structural connection without the hassle of powder loads or gas cartridges using the Bosch NK-138 1-3/8 In. Collated Wood-to-Concrete Nails. Specifically engineered for commercial framing crews, drywall installers, general contractors, and residential remodelers, these industrial-grade steel track pins are designed to securely anchor wood plates, furring strips, and structural studs straight into cured concrete walls or slabs. Outfitted with an advanced knurled shank structure, these heavy-duty fasteners bite deeply into tough masonry substrates, providing an exceptional mechanical lock that holds tight under intense structural load. They serve as an indispensable asset for rapid-fire interior partition framing, basement finishing, and basement track installations.

These contractor-grade strip nails are production-optimized for exclusive use with the Bosch GNB18V-12 Cordless 18V Concrete Nailer. Having undergone rigorous independent laboratory evaluations, the nails and the GNB18V-12 nailer are officially ICC-certified to look, fit, and perform together at peak engineering compliance. This collated nail format drops directly into the nailer's standard 22-shot magazine or the upgraded 44-pin extra-capacity magazine, keeping your crew moving at high velocity without tedious manual reloading. Forged from ultra-tough premium hardened steel to eliminate bending or shattering upon high-impact driving, this massive bulk pack ensures you stay continuously stocked for high-volume commercial production.

Key Features

  • Advanced Knurled Structure: Specialized grooved steel shanks dramatically increase frictional resistance to tightly lock wood components to solid concrete.
  • Engineered for Bosch GNB18V-12: Tailor-made to feed flawlessly and cycle smoothly through the Bosch 18V cordless high-power concrete nailer fleet.
  • Official ICC Tested & Certified: Verified alongside the host tool under precise ICC parameters, guaranteeing strict compliance with modern building code safety specifications.
  • Hardened Structural Steel Matrix: Heavy-duty industrial steel composition resists bending, fracturing, or shearing forces under pneumatic-style cordless impact.
  • Flawless Collated Strip Alignment: High-precision collation strip holds pins securely during transport and breaks away cleanly inside the tool's firing channel.
  • Universal Full Round Head: Traditional full-head configuration maximizes surface area coverage to prevent over-driving or tearing through wood plates.

šŸ’” PRO-TIP: When nailing 2x4 wood plates down to green or freshly poured concrete slabs, use your tool's built-in sliding depth switch to slightly reduce drive penetration depth. Because green concrete lacks the crushing resistance of fully aged, cured stone, dial back the driving depth to prevent the full-round nail head from punching too deeply into your lumber or cracking the aggregate matrix along your chalk line boundaries!
