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.
Bristol wrenches have been in continuous production in the United States since their original introduction. Bristol Wrench Co. utilizes proven methods to manufacture quality spline and hex wrenches, focusing foremost on producing the most effective wrenches possible.
