e.s. socket wrench inserts
The deeply milled ball grooves ensure a secure hold on the e.s. socket wrench inserts.
Surface in perfection
All e.s. socket wrench inserts are finished with a very durable nickel-chrome coating. The special coating procedure increases the resistance capability toward extternal influences significantly. This makes peeling chrome resulting from heavy loads, scratches on the surface and therefore potential rust areas a thing of the past.
Thanks to the perfected "pro" profile, the force is directly ideally on the edges of the screws. This means that the e.s. socket wrench insert can get a grip even on worn screws and improve the force transmission.
The inner square of the e.s. socket wrench inserts is also equipped with a "pro" profile: its enlarged recesses protect the corners of the drive square and slightly curved edges apply force to the surface.
