Bristol Spline L-Keys and Kits   

Our Bristol Spline keys and bits are manufactured from high quality 8650 steel and are heat treated to precise specifications, then black-oxided. If a standard part won’t satisfy your requirement, please contact us for a quotation on custom arm or bit lengths. We stock several standard spline key kits, but can also quote custom kits. All of our products are Made in USA. Contact Bristol Wrench Co. with your specific requirements.

Bristol Spline Screwdrivers and Bits   

Bristol Spline Screwdrivers manufactured by Bristol Wrench Co. are the tools of choice for technicians and mechanics in many industries, including avionics, instruments, radios, aircraft maintenance, printing and engraving. If, instead, you need an adapter to use with a Bristol Spline Bit, those are available in some sizes. Please see our section under the tab “Bristol Spline Custom Tools and Adapters”.

Our screwdrivers have replaceable bits, retained by a set-screw in the recess of a precision-machined bushing which 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, allowing 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. Contact Bristol Wrench Co. with your specific requirements.

Bristol Spline T-Drivers and Bits   

Industrial Spline T-Drivers are available in some of the large spline sizes. These are truly heavy-duty tools, commonly found in industries such as railroad and trucking to maintain airbrakes. The T-Drivers are assembled with a cast-iron handle, a spline-broached bushing, a replaceable spline bit, and a set screw. If, instead, you would prefer a socket with replaceable spline bit, those are available in some diameters, particularly for the spline sizes used in the railroad industry. Please see our section under the tab “Bristol Spline Custom Tools and Adapters”. Contact Bristol Wrench Co. with your specific requirements.
