BRISTOL SPLINE DRIVE
The substantial and effective wrench engagement inherent in the Bristol spline design addresses the problems caused by other systems such as cam-out, socket reaming and rounding of wrenches.
Pioneered 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 socket.
Other drive systems dissipate a significant amount of force into radial thrust tending to expand the socket rather than tighten the screw.

- Applicable socket depths are specified in the dimensional table and notes for the respective screw types.
- Where spline sockets are chamfered, the depth of chamfer shall not exceed 10% of the nominal socket size for sizes up to and including 0.60 in., and 7.5% for larger sizes.
