Proto J5281AM 18mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5281AM is an 18 mm, 12-point hand socket with a 3/8 inch drive, designed for universal and flex-style socket applications. Machined from alloy steel and finished with a chrome plating, this socket provides corrosion resistance and durability under regular shop and field use. The 12-point design engages fasteners at multiple contact positions, reducing the risk of rounding on stubborn or corroded hardware. Overall length measures 1-57/64 inches, making it suitable for use in moderate-clearance fastener locations. It meets ASME B107.5M standards and is a practical choice for mechanics, maintenance technicians, and industrial tradespeople.

This socket is appropriate for general mechanical and maintenance applications where a 3/8 inch drive ratchet or breaker bar is the tool of choice. The universal and flex socket classification makes it well suited for angled or offset fastener access in automotive, industrial equipment, and facility maintenance settings. It is packaged as a single unit and is a direct addition to any 3/8 inch drive socket set requiring 18 mm coverage.
