Suitable for use on spline fasteners and 4, 6, and 12 point fasteners, spline sockets line includes 55 SKUs, in 1/4, 3/8, 1/2, 3/4, and 1 in. drive models. Geometric profile of socket's 12 teeth offers large contact area between tool and spline fastener that allows user to apply more torque without damaging tool or fastener head. Sockets loosen partially rounded hex fasteners and meet requirements for MIL-W-8982/1A. The sockets can be used on spline fasteners, as well as on 4, 6, and 12 point fasteners. The spline socket/fastener system offers higher strength in a more compact profile than conventional fasteners, making it common on military equipment and commercial aircraft.

When a spline socket is placed on a spline fastener, the geometric profile of the socket's 12 teeth provides a large contact area between the tool and the fastener. This lets the user apply more torque with without damaging the tool or the fastener head. Spline sockets can even loosen hex fasteners that have already been partially rounded.

The precise fit between spline socket and fastener also helps prevent rounding or breaking off of fastener edges, which in turn, helps reduce the chance of foreign object damage to machinery. That's because the socket is designed to move the torque load away from the fastener corners, in addition to transferring it over a broader surface area.

Stanley[R] Proto[R] spine sockets are made from aircraft quality steel. They meet the requirements for MIL-W-8982/1A, as well as other leading aerospace and military specifications.
