Bosch Masonry Concrete Nails NB-125 1-1/4 Inch Track Fasteners (Plastic Collated 1000 Pack Zinc Plated Steel Framing GNB18V-12 Cordless Nail Gun)

Bosch NB-125 1-1/4" Zinc-Plated Smooth Shank Plastic Collated Masonry Nails (1,000-Pack)

The Bosch NB-125 1-1/4-inch zinc-plated smooth shank masonry nails fasten cold-formed metal drywall tracks, plywood furring strips, and mechanical brackets directly into poured concrete slabs, pre-cast panels, and structural masonry blocks. Engineered from high-strength carbon alloy steel treated with a protective electro-galvanized zinc coating, these plastic-collated strip pins feed continuously through the Bosch GNB18V-12 cordless 18V concrete nailer without powder cartridges or gas fuel cells. Featuring official ICC-ES building code compliance, a heavy 2-gauge ballistic shank profile, and 1,000 pins per contractor box, they provide commercial drywallers, framers, and MEP contractors with maximum embedment holding capacity and rapid cyclic fastening.

Best Used For:

• Deep Embedment Metal Track to Concrete Pinning: Securing 20-gauge to 16-gauge perimeter drywall floor tracks securely into hard-cured concrete slabs and post-tensioned foundation decks.
• Wood Furring Strip and Backer Board Mounting: Fastening 1x dimensional lumber, plywood nailers, and electrical backer panels directly to concrete masonry units (CMU) and poured foundation walls.
• Mechanical and Electrical Utility Clip Anchoring: Nailing pipe hangers, conduit straps, and junction boxes into structural block and concrete without pre-drilling holes or setting expansion plugs.

Key Performance & Safety Features

• Official ICC-ES Code Compliance: Tested and certified with the Bosch GNB18V-12 cordless nailer to meet commercial structural load and building code inspection requirements.
• Anti-Corrosive Zinc Galvanization: Electro-plated zinc barrier seals out moisture to prevent corrosion, oxidation, and surface rust staining in finished building interiors.
• Continuous Plastic Strip Collation: High-integrity plastic carrier strips ensure smooth, jam-free loading and rapid cyclic firing across 22-shot and 44-shot nailer magazines.
• Extended 1-1/4-Inch Embedment Length: Provides increased penetration depth into high-PSI concrete and mortar joints to deliver higher pull-out and shear load capacities.
• Ballistic Smooth Shank Geometry: High-hardness ballistic point design pierces tough aggregate and masonry cleanly without spalling surrounding concrete surfaces.
• High-Density 1,000-Count Pack: Packed in a heavy-duty bulk box to maximize continuous jobsite production and minimize magazine reload stops.

Technical Specifications

Pro-Tip: Maintain perpendicular 90-degree alignment between the nailer nose and concrete surface when driving 1-1/4-inch pins; keeping the tool flush ensures straight penetration and maximum pull-out holding strength in dense cured concrete.
