Description
The Proto J5421MH is a 21 mm 6-point socket with a 1/2 in drive. The manufacturer states that 6-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, using a radius-corner design that spreads contact stress over a larger area and helps limit slippage.
Per the manufacturer, the TorquePlus internal design minimizes fastener rounding and makes it easier to turn worn, rounded or rusted fasteners. Finish: full polish. Overall length is 1-1/2 in. Sold as a single socket.
