Wiha L Keys provide German Quality for every fastening job. T Handles are wider than a standard screwdriver handle, this offers the ability to deliver greater torque compared with a screwdriver, and the ergonomic shape allows for greater comfort whilst fastening. The L Keys have 100 - 200mm length blades, allowing for greater access for hidden screws. Allen keys protect against the unintentional stripping of fasteners. Since they are used with hexagonal fasteners, they'll “grip” fasteners better than other common screwdrivers and wrenches. This strong gripping action protects fasteners from being stripped during installation or removal. With the side drive on the handle, you are able to loosen over torqued screws with ease.
