Wera 3950 SPKL Stainless Steel Multicolour Hex Key Imperial

The Wera 3950 SPKL 3/8" Stainless Steel Multicolour Hex Key Imperial is the largest in the range, designed for the biggest imperial socket head fasteners where maximum torque and leverage are required. With an overall length of 224 mm, it provides the mechanical advantage needed for heavy fixings in demanding applications. Constructed from stainless steel hardened to the same performance standard as conventional carbon steel, this key prevents the formation and transfer of extraneous rust — making it suitable for marine, outdoor, food-grade, and stainless steel fastener applications. Wera's Hex-Plus profile greatly increases the bearing surface within the screw recess, reducing the notch effect and virtually eliminating screw head destruction even at high torque values. The hexagonal ball tip on the long arm allows angled driving where direct access is restricted, and the rubber sleeve ensures a secure, comfortable grip under load. Multicolour coding makes this 3/8" key immediately identifiable in any professional toolkit.
