The APEX 80377 is a 3/8 inch drive, 6-point, 9 MM full polish chrome socket designed for professional trade use in automotive, mechanical, and general maintenance applications. The off-corner loading design applies force to the flats of fasteners rather than the corners, reducing the risk of rounding under high torque. Large, hard-stamped size markings make identification fast in a cluttered toolbox or on a busy job site. At 0.04 pounds, the socket is lightweight without sacrificing the strength expected in daily professional use.
This socket is suited for residential and commercial maintenance, automotive service, HVAC equipment installation, electrical panel work, and plumbing fixture installation where a 3/8 inch drive tool is required. The 9 MM metric sizing covers a wide range of fastener sizes found on modern mechanical equipment and imported components. Licensed tradespeople and experienced service technicians working in tight or confined areas will appreciate the full polish chrome finish, which resists corrosion and wipes clean easily.
Designed for use with standard 3/8 inch drive ratchets, extensions, and torque wrenches requiring a 6-point 9 MM metric socket.
Always de-energize or shut off the equipment being serviced before applying any socket or fastener tool. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Inspect the socket for cracks or wear before each use and remove from service if deformation is found.
