Hex Key for SAE Fasteners

This Wiha hex key fits 5/32 in SAE hex sockets. The L-shaped handle provides a long arm of 4 3/32 in and a short arm of 1 1/4 in for leverage in tight spaces. It is suited for mechanics and technicians working with imperial fasteners.

Limits of the L-Shape Design

The short arm restricts torque when access is limited to the short end. Chrome plating resists corrosion but the tool is not non-sparking, so it is unsuitable for explosive atmospheres. Insulation is present yet the key is not tether-ready for height safety.

5/32 Inch Tip Decides Fit

The single 5/32 in hex tip determines whether this key matches the fastener. Buyers needing metric sizes, multiple tip options, or a ball-end for angled entry must choose a different tool. Part number 13665 identifies this specific model.

Questions about this item

Which length family should I choose for the Wiha Tools 13665 hex key?

The Short length family provides a compact handle of 4 3/32 in for tight access while still delivering the 5/32 in tip size needed for SAE fasteners.

What does the 5/32 in tip size mean when I use this hex key in a real job?

It fits SAE hex socket screws measuring 5/32 in across the flats, giving a precise, non-slip engagement for automotive and machinery maintenance.

How does the insulated, corrosion-resistant design affect daily use of the 13665 hex key?

The insulated handle protects against electrical shock up to its rated voltage, while the corrosion-resistant chrome finish withstands moisture and shop chemicals for longer service life.
