Wera 3950PKL Stainless Steel Ball End Hexagon Allen Key Imperial 5/16"

The Wera 3950 PKL in 9/64" is a stainless steel imperial L-key designed for hexagonal socket screws where both corrosion resistance and fastener protection are priorities. At 130 mm in total length, this size delivers a good level of torque whilst remaining manageable in confined workspaces. The all-stainless construction directly addresses the extraneous rust problem — when stainless screws are driven with standard steel tools, rust particles can transfer to the fixing. This key eliminates that risk entirely. Wera's Hex-Plus profile ensures a superior fit within the screw head, reducing notching and virtually eliminating recess damage under repeated use. The hexagonal ball end on the long arm provides the flexibility to drive screws at an angle, improving access to awkward fixing positions. Features and Benefits: • Stainless steel construction eliminates extraneous rust on stainless fixings • Hex-Plus profile reduces notching and protects the screw recess • Ball end on long arm for off-axis "round the corner" screwdriving • Imperial sizing for hexagonal socket head screws Specifications: Size: 9/64" Total Length: 130 mm Contents: 3950 PKL L-key, Imperial, stainless, 9/64" x 130 mm
