The Wera 3950 SPKL 1/4" Stainless Steel Multicolour Hex Key Imperial is a go-to size for larger imperial socket head screws across engineering, manufacturing, and maintenance applications. At 185 mm in length, it delivers the torque arm required for tighter fastening jobs. Stainless steel construction, hardened to the same strength as conventional carbon steel tools, means this key actively prevents extraneous rust from forming and transferring — particularly important when working with stainless hardware or in corrosive conditions. Wera's Hex-Plus profile provides an enlarged contact surface within the screw head, substantially reducing the notch effect and protecting against screw head rounding. The hexagonal ball tip on the long arm allows angled tool entry, giving access to fasteners that would otherwise be unreachable. A rubber sleeve ensures a comfortable grip during prolonged use, and the distinctive multicolour coding keeps this 1/4" key easy to locate at a glance.
