Product Description
Manufacturer Part Number: 05021737001
We questioned the classic L-key design, since all too often the screw head recess is rounded out, meaning screws can no longer be tightened or loosened - and so the user finds the L-key slipping out of the recess. Wera Hex-Plus tools have a larger contact surface in the screw head. The notching effects are reduced and thereby the deformation of the screws. At the same time, as much as 20 % more torque can be applied.
Hexagon screws can endure a problem because the contact surfaces delivering the power from the conventional tool, is transferred to the screw via very small surface areas. The consequence: the screw can become damaged (rounding out). Hex-Plus tools have a greater contact surface that prevents this from happening! At the same time, as much as 20 % more torque can be applied. Good to know: Hex-Plus tools fit into every standard hexagon socket screw!
L-keys with BlackLaser surface treatment for outstanding surface protection and long service life. High corrosion protection.
The size of each L-keys has been engraved by a laser. In addition SPKL L-keys have a colour coding according to sizes - for simple and rapid accessing of the required tool. Making it easy to find the right tool.
The wear-resistant clip material ensures that the L-keys are securely held yet are easy to remove.

I don't know how Wera does it, but their hex wrenches fit and grip where other wrenches fail. Maybe it's the inset hex design or maybe they actually machine more precisely. All I know is if you are tired of cheapo wrenches stripping out your hex heads, get this set and leave the stripped screws behind!

The item was loose in a padded envelope, but the tool looks very nice. The wrench I tried out worked great, good for small spaces.

got these for 5.42, at that price i couldnt not buy it. some reviewers commented about lack of ball head, but the thing is, if you dont NEED ballhead to access a certain fastener, then straight head is better. the short size gets them into some situations that a long head wouldnt work for. ultimately to handle any task you would need all four permutations of ball and straight, long and short.
