Description 816 R Bit-Hand Holder 6.3 mm (1/4"") High-quality bit holder from Wera in Kraftform Plus Design. Kraftform Plus screwdrivers bring higher power transmission with low effort and spare the entire hand-arm system - even in continuous use. The shape of the force shape handle, which is perfectly adapted to the hand, prevents hand injuries such as bubbles and sleds. The hard materials (black grip zones) used for the handle are quick to grasp without the risk of ""solid-sticking"" of the skin on the handle. The softer, ""slip-resistant"" zones (green) allow the lossless transmission of high forces. The identification of the handle with screw symbol and profile size makes it easy to find the screwdriver in the tool bag and at the workplace. The hexagonal roll protection prevents annoying rolling away at the workplace. Technical data: Drive (screwdriver): 1/4"" (6.3 mm) Application area (screwdriver): Workshop DIN standard (screwdriver):
