Product Description
Martin - 3/4" Drive Impact Socket
Martin Sprocket & Gear — 76 Configurations
Martin impact tools are forged for the kind of abuse that destroys lesser brands. Every piece in the Martin impact line is manufactured from premium alloy steel, heat-treated to withstand the repeated shock loads of pneumatic and electric impact drivers. These aren’t chrome sockets dressed up for the shelf — they’re black oxide finished workhorses built for industrial maintenance, heavy equipment repair, and production floor operations where downtime costs real money.
Martin has been manufacturing power transmission and industrial tools in the United States since 1928. Their impact tools carry that same commitment to precision and durability. Each piece is manufactured to exacting tolerances, ensuring positive engagement with fasteners and minimal wobble under load. The black phosphate finish resists corrosion while providing a surface that won’t slip in oily hands.
Available in 76 configurations (34IS-NA-0-Deep, 34IS-NA-1-Deep, 6624, 16624, 6626 and 71 more), this product covers the range of sizes and configurations most commonly needed in professional shops and industrial maintenance operations.
