Wiha's Combination Wrenches feature a 12-point box-end design doubles access-angles of a 6-point opening. The point-contacts apply force to the flat sides of the fastener head—rather than the corners—to prevent the fastener head from rounding off. The open-end is angled 15 degrees for flipping the wrench between rotations to maximize rotations and the box-end offset 15 degrees for finger clearance and working around obstructions that limit access to the fastener.

The wrenches consist of premium-quality tool steel, have a Chrome-plated satin finish for corrosion protection, and the size profiles are boldly stamped on the handle for easy identification. 

Designed and engineered by Wiha Germany, manufactured by Wiha globally and are backed by the Wiha No Hassle Guarantee.
