Simpson 1/2 in. Mechanically Galvanized Carbon Steel Concrete Pins from Simpson are built for professionals who need fast, dependable fastening into tough substrates without slowing down the job. Engineered for gas-actuated nailer systems and tested to perform in A36 and A572 structural steel, concrete, CMU block, and sand-lightweight concrete over metal deck, these pins deliver the rugged reliability that demanding construction work requires. Each 1,000-count package includes a fuel cell, so crews can load up and get straight to work.

Key Features

• Compatible with Simpson G3 and GCN-MEPMAGKT nailers as well as most major brands - broad tool compatibility means these pins integrate into your existing workflow without requiring dedicated or proprietary equipment.
• Approved for use in A36 and A572 steel, concrete, CMU block, and sand-lightweight concrete over metal deck - versatile substrate range reduces the need to stock multiple fastener types across different phases of a project.
• Patented 10-fastener strip with break-away plastic design - strips feed consistently into compatible nailers, helping maintain a smooth, uninterrupted fastening pace on the job site.
• Mechanically galvanized carbon steel construction - the mechanically galvanized finish provides a protective coating over a strong carbon steel core, suited for the wear demands of direct fastening applications.
• 1,000-count package includes 1 fuel cell - having the fuel cell bundled in means no separate sourcing step before getting started, keeping the project on schedule.
