Professional SAE Hex Key 3/8 Inch
The Wiha Tools 33487 is a single-tip hex key manufactured from HAWA material with a black oxide finish. It serves technicians and tradespeople who require a reliable SAE driver for 3/8 inch fasteners in maintenance, assembly or repair tasks. The insulated, non-magnetic design adds safety when working near electrical components.
Build Integration and Clearance
Both arms measure 5 57/64 in, giving equal reach whether the short or long end is engaged. The uniform length frees up workflow by eliminating the need to switch tools for leverage versus access, while the tether-ready absence keeps the profile slim for tight clearances. Corrosion-resistant coating protects the tool in damp or chemical environments.
Durability and Handling
Black oxide resists surface oxidation during daily use and the HAWA construction withstands high torque without rounding. Insulated handles reduce heat transfer and electrical risk, while the non-magnetic tip prevents unwanted ferrous debris adhesion. No moving parts or lubrication points mean consistent performance over the tool's service life.

Questions about this item
Will the 3/8 in tip round off before the HAWA steel yields under sustained torque?
The HAWA steel tip resists rounding during sustained torque, and the black-oxide finish adds surface hardness without changing the 3/8 in SAE profile.
Does the black-oxide coating stay cool and quiet during all-day repetitive use?
As a non-powered hand tool it generates no heat or noise; the black-oxide finish is corrosion resistant and does not affect temperature or sound.
What drive tool is needed to turn this 5 57/64 in long-arm hex key?
No drive tool is required — the L-shaped key is turned directly by hand using either the long or short arm.
