The APEX 80418 is a 3/8 inch drive hex bit socket designed for driving and removing internal hex fasteners in professional trade and industrial applications. The base socket is constructed from heat-treated alloy steel for structural durability and extended service life. The hex bit itself is manufactured from S2 tool steel, which provides high impact strength and resistance to cam-out under load. At 1.653 inches in length and weighing 0.14 pounds, this is a compact, single-piece socket suited for tight-access fastener work in mechanical, HVAC, plumbing, and electrical assembly tasks.
This bit socket is sized at 7/32 inch in the SAE standard, making it appropriate for internal hex cap screws, set screws, and machine bolts commonly found in equipment panels, valve assemblies, motor mounts, and structural hardware. The 3/8 inch square drive interfaces with standard 3/8 inch ratchets, extensions, and breaker bars, giving technicians flexibility across a wide range of drive tools already in their kit. It is sold individually and suited for professional bench work or field service.
Designed as a standard 3/8 inch drive hex bit socket for use with any 3/8 inch drive ratchet, extension, or torque wrench accepting square drive accessories.
Installation and removal of hex fasteners should be performed by a qualified technician using properly rated drive tools. Ensure the bit socket is fully seated in the fastener recess before applying torque to prevent cam-out or fastener damage. Do not use impact drivers unless the socket is rated for impact use. Inspect the socket for wear or cracking before each use and replace if deformation is present.
