Spline Sockets
Spline sockets on spline fasteners deliver up to twice the amount of torque that would be applied to a bi-hex fastener from a bi-hex socket, meaning that a spline drive socket is useful for tightening to high torque loads.
A spline socket is designed to tighten and un-tighten spline fasteners but is also ideal for use on 4-point, 6-point (hex) and 12-point (bi-hex) fasteners.
