Wera 5022720001 Stainless 3950 PKL/9 Hex Key Set Ball-Point Long Arm Hex Plus 9-Piece

Overview

Wera 3950 PKL/9 is a stainless hex key set that blends rust resistance with precision engineering. Built from 100% stainless steel, it helps keep stainless fasteners clean, while a vacuum ice-hardened process delivers the hardness needed for demanding tasks. The Hex-Plus design increases the contact area with screw recesses, enabling up to 20% more torque transfer and reducing the chance of fastener wear. A ballpoint on the long arm facilitates quick alignment and operation in tight or awkward spaces. The keys are designed to resist shifting after frequent removal, thanks to a non-wearing material that helps maintain fit over time.
