Wera 3950 Stainless Steel Ball End Hexagon Allen Key Metric 3950 PKL

The Wera 3950 PKL in 10mm is the largest key in this stainless steel range, designed for M12 socket head screws and heavy-duty engineering tasks where maximum torque and a corrosion-free result are both required. Built from high-grade stainless steel, this key ensures no extraneous rust is imparted to stainless fixings — an indispensable quality for offshore, marine, hygienic processing, and architectural steelwork applications. The Hex-Plus profile delivers superior engagement within the screw head, distributing torque over a greater contact area, reducing notching forces, and effectively eliminating the risk of recess destruction. The long arm's ball end allows the tool to be driven at an angle, providing access to otherwise inaccessible fixings without the need for additional adaptors. Features and Benefits: • Stainless steel construction prevents extraneous rust on stainless fixings • Hex-Plus profile protects screw recesses and extends screw life • Ball end on long arm for angled "round the corner" screwdriving • Metric sizing Contents: 3950 PKL L-key, metric, stainless, 10 x 224 mm Specifications: Key Size: 10mm Overall Length: 224mm
