Wera 3950 Stainless Steel Ball End Hexagon Allen Key Metric

The Wera 3950 PKL in 8mm is engineered for M10 socket head screws and heavy-duty applications in structural engineering, plant maintenance, and industrial fabrication where reliable torque transmission and rust-free performance are critical. The high-grade stainless steel construction prevents extraneous rust from being introduced to stainless fixings, making this key suitable for use in demanding environments such as offshore, marine, or food-grade installations. The Hex-Plus profile provides a larger contact surface within the screw head, dispersing load more evenly, reducing notching, and significantly prolonging the life of the screw recess. The ball end on the long arm supports angled driving, giving you greater access in confined spaces without sacrificing control.
