The APEX 80385 is a 3/8 inch drive, 6-point, 17 MM chrome socket designed for professional use in mechanical, HVAC, and general trade work. Built with a full polish chrome finish, this socket resists corrosion and cleans up easily on the job. The off-corner loading design directs force onto the flats of fasteners rather than the corners, reducing the risk of rounding fastener heads during high-torque applications. Large, hard-stamped size markings make quick identification possible even in low-light conditions. At 0.11 pounds and a compact 0.984 inch length, it fits into tight spaces where longer sockets cannot reach.
This socket is suited for residential and commercial service work across mechanical trades, including HVAC equipment service, plumbing fixture installation, and electrical panel work. The 3/8 inch drive fits standard 3/8 inch ratchets and extensions commonly found in trade toolkits. The 17 MM size is frequently encountered on metric fasteners used in condensing units, air handlers, and imported mechanical equipment. Sold individually, this socket works as a direct addition to an existing socket set or as a standalone replacement for a lost or worn piece.
Designed for use with standard 3/8 inch drive ratchets, breaker bars, and extensions. Fits 17 MM metric fasteners across a wide range of mechanical and trade equipment.
This socket is installed by qualified trade professionals using standard 3/8 inch drive ratchets or impact-rated extensions where applicable. Always confirm the fastener size before applying torque to avoid rounding. Ensure the socket is fully seated on the fastener before turning. Follow equipment manufacturer service procedures and applicable codes when servicing mechanical systems.
