The Wera 3950 SPKL 5/16" Stainless Steel Multicolour Hex Key Imperial is built for heavy-duty imperial socket head fasteners, offering substantial torque capability across a total length of 195 mm — ideal for demanding engineering and maintenance tasks. The stainless steel body is hardened to match the strength of conventional carbon steel tools, while inherently resisting and preventing the transmission of extraneous rust. This makes it an excellent choice for stainless fixings, marine environments, and applications where component cleanliness is essential. Wera's Hex-Plus profile significantly increases the contact area within the screw head recess, reducing the notch effect and nearly eliminating screw head damage under high torque. The hexagonal ball tip on the long arm allows you to pivot the tool and drive at an angle where straight-on access is not available. The rubber sleeve provides a firm, comfortable grip, and multicolour size-coding means this 5/16" key stands out in any toolkit.
