With a 8-Inch (203 mm) shaft, the Klein Tools 3/8-Inch (10 mm) Keystone-Tip Screwdriver features quality tempered steel, carefully heat-treated for ideal durability. An insulated, Cushion-Grip handle and integral flanges on the inside provide a solid, twist-resistant blade anchor that allows for optimal torque and comfort while offering protection against electric shock. The 8-Inch heavy duty round shank is exceptionally strong and made of carefully heat-treated and tempered steel for wrench-assisted turning. The hex bolster on the blade at the handle reinforces the shank for hard use. The shaft has integral flanges that provide an extra-strong, torque-proof anchor in the handle and will not bond or twist in normal use. The blade is fully chrome-plated for corrosion resistance with a durable black tip that is precision-machined and ground with square edges to fit screw openings securely. The cushion-grip handle resists slippage which allows you to apply greater torque. The patented tip-indent quickly identifies the type of screwdriver and screwdriver tip orientation. This Klein screwdriver has an overall length of 13-7/16-Inch (341 mm) and meets or exceeds applicable ASME/ANSI specifications. The Klein 602-8 3/8-Inch keystone-tip screwdriver is sold one item per package.
