Product Description
Martin - 3/8" Drive Chrome Socket
Martin Sprocket & Gear — 108 Configurations
Martin sockets are the professional’s choice for industrial and heavy-duty applications. Manufactured from premium chrome vanadium or alloy steel (depending on the application), each socket is precision-machined to maintain tight tolerances on fastener engagement. The 6-point design provides maximum contact area on hex fasteners, reducing the risk of rounding — critical when working with hardened or corroded bolts in maintenance environments.
Martin Sprocket & Gear has been building tools and power transmission components in the USA since 1928. Their socket lines reflect decades of feedback from maintenance professionals, fleet mechanics, and industrial operations teams who need tools that perform shift after shift without failure.
This product includes 108 variants (38CS-NA-0-12pt-Deep, 38CS-NA-1-12pt-Deep, 38CS-NA-11-12pt-Deep, 38CS-NA-12-12pt-Deep, 38CS-NA-13-12pt-Deep and 103 more) covering the most common sizes for professional use.
