Wera 950 SPKL Hex-Plus L-Key with Ball End, 6 mm, Chrome Vanadium Steel, BlackLaser Finish 05003669001

In a busy automotive workshop, a technician reaches for this Wera L-key to tighten a recessed hex socket screw on a brake caliper. The long arm with ball end allows working at an angle, while the Hex-Plus profile grips the screw head firmly, preventing rounding even under high torque. The short arm provides extra leverage for stubborn fasteners, and the colour-coded sleeve makes size identification quick.

Why choose it

The Hex-Plus geometry is a genuine innovation: instead of point contact, it provides larger contact surfaces in the screw head, which significantly reduces the risk of rounding and extends tool life. The BlackLaser surface treatment offers excellent corrosion resistance and a precise fit. The ball end on the long arm allows fast, secure screwdriving even in hard-to-reach areas, while the short arm delivers high torque for final tightening or breaking loose.

Ideal use cases

• Professional mechanics and technicians
