This is a single 1/4-inch drive 12-point socket in 5/16-inch size from Proto – Stanley's industrial-grade brand.


The TorquePlus feature is what sets it apart – it's a radius-corner design that shifts contact stress away from the fastener corners and spreads it across a larger area of the socket.
That means less rounding of bolt heads, better torque transfer, and it even works on rusted or slightly rounded fasteners that other sockets would just slip on.

If you're working on older equipment, automotive restoration, or anything with crusty bolts, this socket is a handy addition to your kit.
