Proto J5277AM 14mm 12-point 3/8 Drive Hand Socket

Product Description

The PROTO J5277AM is a 14 mm, 12-point hand socket designed for 3/8 inch drive ratchets and extensions. Built from alloy steel with a chrome-plated finish, it delivers corrosion resistance and durability under daily shop use. The 12-point configuration allows engagement from multiple positions, which speeds up fastener access in tight or awkward locations. At 1-7/8 inches overall length, it fits standard hand-tool setups without adding unnecessary bulk. This socket is suited for professional technicians who need reliable, accurate fastener drive in automotive, mechanical, and general maintenance applications.

This socket is used in automotive repair, fleet maintenance, and general mechanical service where 14 mm fasteners are common. The 3/8 inch drive size makes it compatible with a wide range of mid-range ratchets, torque wrenches, and extensions found in professional tool sets. Its chrome finish and alloy steel construction hold up in both shop and field environments. Technicians working on engine components, suspension hardware, and equipment assemblies will find this socket a standard addition to a 3/8 inch drive set.
