Wera 950 PKL L-key
The Wera 950 PKL L-key, metric, size 4.0 mm with a long arm length of 140 mm (part number 05022058001) is a metric L-key designed for operating internal hexagon screws. The product combines Wera's Hex-Plus profile with a ball-end on the long arm and a rack-chrome-plated surface for corrosion protection. The size marking is laser-engraved to ensure resistance against wear.
Design and function
- Hex-Plus profile increases the contact surface in the screw head and reduces notching.
- Ball-end on the long arm allows screwing with angled access (working at an offset angle).
- Rack-chrome-plated (chrome coating) for improved corrosion protection.
- Laser-engraved size indication for better wear resistance.
Technical relevance
The Wera 950 PKL L-key, metric, size 4.0 mm with a long arm length of 140 mm (part number 05022058001) is intended for internal hexagon screws. The Hex-Plus profile system reduces the notching effect in the screw's internal profile and allows for higher torque transfer (up to 20% higher torque according to the manufacturer's description) compared to traditional hexagonal profiles. The ball-end on the long arm allows for work in difficult installation situations where axes cannot be fully aligned.
Typical applications
The product is described by the manufacturer as an L-key for internal hexagon screws, where the ball-end allows for secure operation with screw axis deviation. These applications are indicated in the manufacturer's documentation.
