Product Description

The PROTO J5216B is a 1/2 inch, 12-point hand socket designed for use with a 3/8 inch drive ratchet or breaker bar. Constructed from alloy steel with a black oxide finish, this socket delivers reliable corrosion resistance and durability in demanding shop and field environments. The overall length of 1.125 inches keeps it compact for use in tighter access areas. It meets ASME B107.1 standards and carries a limited lifetime warranty. Licensed tradespeople and maintenance technicians working on mechanical, HVAC, plumbing, and electrical equipment will find this socket a dependable addition to a service kit.

This socket suits general fastener work across residential and commercial applications. It is well suited for technicians who need a compact, standard-drive socket for routine service tasks involving 1/2 inch fasteners.
