7 Piece Torx L-Shape Hex Key Set

The Wiha Tools 37190 set provides seven L-shaped Torx keys for driving recessed fasteners in automotive, machinery and electronics work. Chrome vanadium molybdenum steel construction delivers professional-grade durability for technicians and serious DIY users who need reliable engagement on Torx profiles.

Questions about this item

How do I insert each L-shaped key into a Torx fastener without rounding the corners?

Align the long arm fully into the recess before applying force; the short arm is only for final tightening or breaking loose stuck screws.

What upkeep will the chrome vanadium molybdenum steel keys need over time?

Wipe them clean after use and apply a light oil film to the black finish to prevent surface corrosion.

At what point does the black finish wear through under daily heavy use?

The coating lasts through thousands of cycles; once the underlying alloy shows, the key still works but loses its corrosion protection.
