Wera 9 Piece Ball End Hexagon Allen Key Set Metric

The Wera 9 Piece Ball End Hexagon Allen Key Set Metric is a professional-grade L-key set designed for driving hexagonal socket screws across a wide range of assembly and installation tasks. At the heart of this set is Wera's Hex-Plus profile, which increases the contact surface area within the screw head. This reduces notching and cam-out, significantly lowering the risk of damaging screw recesses — a common frustration for mechanics, engineers, and contractors working with hex fasteners repeatedly. The ball-end on the long arm allows the key to engage screws at an angle, making it ideal for confined or awkward spaces where a straight approach isn't possible. This makes the set well suited to assembly work, machine maintenance, and general engineering applications where access is restricted. The BlackLaser surface treatment offers corrosion protection and extends the working life of the keys, making them a reliable choice for site and workshop use. Laser-engraved size markings ensure the labelling remains legible throughout the life of the tool. The keys are housed in a wear-resistant clip holder, keeping sizes organised and allowing quick, single-handed removal.
