Max-Gain Systems, Inc. sells the entire range of Bristol Wrench Company spline products, including (both short and long), as well as the Bristol spline screwdriver handles preferred by professional service technicians and the straight spline bits to fit them. The spline “L” keys are similar to the more common “hex” wrenches in appearance, but use the far superior and more efficient spline configuration.

About the Bristol Spline Drive System

Decades ago, Bristol engineers invented the Bristol Spline Drive System for use in electro-mechanical instruments. They required screws and wrenches that could stand up to industrial environments, vibrations, and frequent removal and resetting. The effectiveness of their invention, for that original application and thousands more since, has never been surpassed.

Our Bristol Spline keys and bits are manufactured from high quality 8650 steel and are heat treated to precise specifications, then black-oxided. All of our products are Made in USA.

Bristol Spline Screwdrivers, manufactured by Bristol Wrench Co., are the tools of choice for technicians and mechanics in many industries. Including but not limited to: avionics, instruments, radios, aircraft maintenance, printing and engraving.

Our screwdrivers have replaceable bits, retained by a set-screw in the recess of a precision-machined bushing. The bushing is broached to the unique size and shape of the bit. The plastic handle is manufactured with material and method which provides superior performance and durability. The handle is specifically designed with a size and shape proportional to the size of the bit and fastener. This allows the technician to have the necessary “feel” to properly apply required torque and to conveniently work on a wide range of tasks.

This combination of features is unmatched in the tool industry. These are not “one size fits all” drivers. They are, instead, drivers designed to provide exceptional performance. Standard and special length replacement bits are available.
The substantial and effective wrench engagement inherent in the Bristol 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. 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.

  • Excellent for demanding applications
  • Especially indicated for set screws and smaller cap screws requiring severe tightening, and for screws with shallow sockets.
  • For frequent removal and resetting of screws and plugs, such as for tool inserts, purge screws, drain/filler plugs, template retainers, and replacement of worn parts.
  • In applications requiring softer screws such as stainless steel or non-ferrous materials.
