Wera 3950PKL Stainless Steel Ball End Hexagon Allen Key Imperial 3/8" 3950 PKL inch

The Wera 3950 PKL in 3/8" is the largest key in this stainless steel imperial range, designed for high-torque fastening of large hexagonal socket screws in professional and industrial applications. With a total length of 224 mm, the long arm provides substantial leverage, making light work of even the most demanding fastenings. The stainless steel construction is especially important at this size, where high clamping forces could otherwise cause standard steel tools to introduce rust contamination to stainless fixings. Wera's Hex-Plus profile ensures the greatest possible contact area within the screw head, reducing notching and virtually eliminating the risk of recess destruction — even at higher torque levels. The ball end on the long arm maintains the ability to drive screws at an angle, preserving accessibility even in confined industrial environments. Features and Benefits: • Stainless steel construction prevents rust contamination on stainless fixings • Hex-Plus profile delivers maximum contact surface under high-torque use • Ball end on long arm for angled screwdriving in restricted locations • Imperial sizing for hexagonal socket head screws Specifications: Size: 3/8" Total Length: 224 mm Contents: 3950 PKL L-key, Imperial, stainless, 3/8" x 224 mm
