The APEX 80531 is a 3/8 inch drive, 12-point, 17 MM full polish chrome socket designed for professional use in mechanical, HVAC, plumbing, and electrical service work. Built to handle repeated heavy use, the off-corner loading design applies force to the flats of fasteners rather than the corners, reducing the risk of rounding damaged or corroded hardware. Large, hard-stamped size markings allow for fast identification in a cluttered toolbox or bag. The full polish chrome finish resists corrosion and makes the socket easy to clean after use in greasy or dirty environments.
This socket suits a wide range of trade applications where a 3/8 inch drive tool is standard. It is appropriate for HVAC equipment panels, motor mounts, compressor brackets, electrical enclosures, and general mechanical fastening tasks. The 17 MM size covers a common fastener dimension found on imported and domestic mechanical equipment. At 2.5 inches in length, it fits into moderately tight spaces without requiring a deep socket extension.
Designed for use with any standard 3/8 inch drive ratchet, extension, or torque wrench accepting 3/8 inch square drive tooling.
Licensed technicians and trade professionals should confirm the fastener size before applying torque to avoid slippage or rounding. Always ensure the socket is fully seated on the fastener before turning. Inspect the socket for cracks or deformation before each use, and do not use impact drivers unless the socket is rated for impact service.
