spline sockets

Stanley Proto now offers a line of spline sockets. The line includes 55 SKUs, in 1/4-, 3/8-, 1/2, 3/4- and 1-inch drive models. Standard depth and deep sockets are available in the three smaller drive sizes. The sockets can be used on spline fasteners, as well as on four-, six, 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. Thatâ„¢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.
