Simpson GDP-75KT 3/4 in. Concrete Pins for Gas-Actuated Nailers (1,000-Pack with Fuel Cell) from Simpson are mechanically galvanized carbon steel fasteners built for fast, dependable direct fastening across a wide range of structural substrates. Engineered to drive cleanly into concrete, CMU block, A36 and A572 structural steel, and sand-lightweight concrete over metal deck, these pins are backed by Simpson's extensive field testing program to ensure consistent quality and performance on demanding jobsites. Each kit includes 1,000 pins and 1 fuel cell, giving crews everything they need to start fastening right away.

Key Features

• Compatible with Simpson G3 and GCN-MEPMAGKT nailers as well as most major-brand gas-actuated tools - broad tool compatibility means fewer workflow interruptions and greater flexibility across different crews and equipment setups.
• Approved for use in A36 and A572 steel, concrete, CMU block, and sand-lightweight concrete over metal deck - versatile substrate coverage lets a single fastener handle multiple application types on the same project.
• Patented 10-fastener strip with break-away plastic design - consistent, reliable feeding through compatible nailers reduces jams and keeps fastening moving at production pace.
• Mechanically galvanized carbon steel construction - provides a durable corrosion-resistant finish suited to tough construction environments without sacrificing driveability.
• Includes 1 fuel cell with the 1,000-pin pack - a complete, ready-to-use kit reduces trips to the supplier and keeps work on schedule.

Why This Product

• Field-tested reliability from a trusted fastening brand - Simpson's direct fastening systems are extensively tested to meet professional demands, so contractors can drive these pins with confidence in critical structural connections.
• Wide substrate and tool compatibility in a single fastener - whether the application calls for driving into concrete, structural steel, or CMU block, and whether the crew is running Simpson-brand or other major-brand gas nailers, these pins are engineered to perform across the board.
• Patented strip design for uninterrupted production - the break-away plastic 10-fastener strip feeds consistently through compatible tools, minimizing downtime and helping crews maintain a steady fastening rhythm on large jobs.
• Everything needed to get started is included - pairing 1,000 pins with a fuel cell in one kit eliminates the need to source components separately, simplifying procurement and reducing jobsite delays.
