The Bristol Spline Drive

Developed by Bristol, the multiple spline drive system is recognized by design
engineers as the superior method of transmitting torque because nearly 100% of
wrenching force is applied at right angles to the load bearing spline surfaces of the

Other drive systems dissipate a significant amount of force into radial thrust,
tending to expand the socket rather than tighten the screw.

The substantial and effective wrench engagement inherent in the Bristol design
addresses the problems caused by other fastening systems such as cam-out, socket reaming and "rounding" of wrenches.

Decades ago, Bristol engineers invented the Bristol Spline Drive System for use in
electromechanical instruments. They required screws and wrenches that could
stand up to industrial environments, vibrations, and frequent removal and resetting.

Bristol wrenches have been in continuous production in the United States since their
original introduction
