Wiha L Keys provide German Quality for every fastening job. The L Keys have 91 - 231 mm length blades allowing for access to deep set recessed 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. The holder for the hex key set also provides an easy way to carry and store the Allen keys. Common key sizes are stored in the holder where they are easily seen. Simple, rapid operation with solid stopping point for L-keys.
