Description
The Proto J5531M is a 3/4 in drive, 31 mm, 12-point socket. The manufacturer states that 12-point sockets suit stubborn or damaged fasteners and fasteners made from soft materials, and that the TorquePlus design engages the fastener flats rather than the corners.
Per the manufacturer, the radius-corner configuration shifts contact stress away from the fastener corners and spreads it over a larger area of the socket, which helps minimize slippage. It has a ball detent design. Satin finish; nut depth 13/16 in, bolt clearance depth 1-5/16 in, overall length 2-7/32 in. Sold as a single socket.
