The Proto PRO5426M is a professional-grade shallow chrome socket designed for 1/2" drive tools. Its 12-point design provides multiple contact points for a secure grip on fastener flats, while the ball detent mechanism keeps the socket firmly seated on the drive during use — ideal for demanding industrial and MRO applications.
The 26mm shallow profile makes this socket particularly well-suited for servicing lawnmower engines, small engines, and a wide range of general mechanical tasks. Built to Proto's industrial standards, this socket delivers the durability and reliability professionals depend on for everyday use.
