Hex and 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.

The drivers 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 in hex and Bristol Spline fastening applications. Standard and special length replacement bits are also available.
