Simpson 1 in. Mechanically Galvanized Carbon Steel Concrete Pins for Gas-Actuated Nailers - 1,000-Pack with Fuel Cell delivers the professional-grade direct fastening performance that demanding concrete, steel, and masonry applications require. Built by Simpson Strong-Tie as part of a full range of direct fastening systems engineered for rugged reliability, these 1 in. carbon steel pins are mechanically galvanized for corrosion resistance and arrive in a ready-to-work kit that includes 1,000 pins and a fuel cell - so crews can drive fasteners into concrete, CMU block, structural steel, and sand-lightweight concrete over metal deck without stopping for supplies.

Key Features

• Compatible with Simpson Strong-Tie G3 and GCN-MEPMAGKT gas-actuated concrete nailers as well as most major brands - broad tool compatibility means these pins integrate into the equipment your crew already owns, reducing the need to source separate fasteners for different nailers on the same site.
• Approved for use in A36 and A572 steel, concrete, CMU block, and sand-lightweight concrete over metal deck - wide substrate coverage allows a single fastener solution to handle the varied attachment points common on commercial and structural jobsites.
• Patented 10-fastener strip designed with break-away plastic - the strip-feed design promotes consistent, efficient pin loading so the nailer stays in the operator's hands and work keeps moving at full pace.
• Mechanically galvanized carbon steel construction - the galvanized finish provides a corrosion-resistant coating while the carbon steel core delivers the hardness and drive performance needed for direct fastening into hard substrates.
• 1,000-count pack includes 1 fuel cell - the kit arrives complete, eliminating a separate fuel purchase and allowing a full production run to start immediately upon delivery.

Why This Product

• A complete, ready-to-drive kit - pairing 1,000 concrete pins with an included fuel cell means no separate sourcing of consumables before the job starts, keeping project timelines tight and reducing last-minute supply runs.
• Engineered and field-tested by Simpson Strong-Tie - Simpson Strong-Tie extensively tests its direct fastening systems to ensure quality and performance under the most demanding professional conditions, giving contractors confidence in every driven pin.
• Versatile substrate compatibility reduces fastener SKU complexity - approval for structural steel grades A36 and A572, concrete, CMU block, and sand-lightweight concrete over metal deck means one part number covers a broad range of attachment scenarios on the same project.
• Strip-feed strip design supports high-volume output - the patented 10-fastener break-away plastic strips are purpose-built to keep the nailer cycling efficiently, supporting the fast-paced demands of production framing and structural attachment work.
