The wera 950 spks imperial allen key in 5 64 is one of the smallest sizes in the range, purpose-built for working with fine imperial socket head fasteners in precision applications such as electronics, optics, and miniature mechanical assemblies. At 50 mm in length, it delivers excellent control in confined or delicate working environments. Wera's hex-plus profile maximises contact between the tool and the screw head, an especially important feature at this size where the risk of fastener damage is highest. The multicolour-coded plastic sleeve aids rapid identification and offers a comfortable, sure grip even in cold conditions. The hexagonal ballpoint on the long arm provides the flexibility to work at an angle where direct access is not possible. The blacklaser surface treatment delivers outstanding corrosion resistance, and the laser-engraved size marking ensures the key remains identifiable throughout its working life.
