T-greep inbussleutel Wiha 334R

The Wiha 334R T-handle hex key is a single-piece metric hex key designed for high torque transfer with minimal effort. The blade is made from chrome-vanadium steel, through hardened and nickel-plated for durability and corrosion resistance. The Wiha Classic T-handle provides a secure grip and allows effective torque application in confined spaces while the lightweight construction (approx. 26 g) supports convenient handling.

Advantages

The through-hardened, nickel-plated chrome-vanadium blade ensures long service life and reliable strength. The Wiha Classic T-handle design improves grip and torque control, and the compact single-piece construction reduces play between handle and blade. From size 3 mm the integrated MagicRing of spring steel secures all standard hex screws regardless of screw material or orientation.

How to use

Select the correct metric size for the hex screw, insert the blade fully into the screw head, and apply steady force to the T-handle to tighten or loosen the fastener. Use the long arm for reach and the short arm for higher torque. Ensure the MagicRing (if present) engages the screw head to help retain the screw during insertion or removal.

Recommendations

Use the tool within its intended size range and avoid applying impact forces. Keep the blade clean and free of debris; store in a dry place to preserve the nickel plating and prevent corrosion.
