Wera 3950 Stainless Steel Ball End Hexagon Allen Key Metric 3mm

The Wera 3950 PKL in 3mm is a versatile and frequently used size, well suited to M4 socket head screws found across a broad range of engineering, fabrication, and assembly tasks where stainless fixings are common. High-grade stainless steel construction means this key won't leave rust contamination on stainless screws — a particularly important consideration in food processing, marine, or medical environments. The Hex-Plus profile provides enhanced engagement within the screw head, reducing notching effects and protecting the recess from premature wear. With a ball end on the long arm, you can approach fixings at an angle, making it easier to work in confined or restricted spaces without repositioning. 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, 3 x 123 mm Specifications: Key Size: 3mm Overall Length: 123mm
