Wiha 41604 Screwdriver Bit Set

The Wiha 41604 Screwdriver Bit Set contains five T10 Torx bits, each 25 mm long with a 1/4" hexagonal shank. Manufactured in Germany, these bits are designed for reliable fastening of T-shaped screws with a 90° angle between the thread and the screw head. Wiha's bit concept simplifies selection by focusing on screw shape only, and the set is suitable for both manual use and power tools thanks to a patented torsion zone that increases durability.

Advantages

These Torx bits feature a patented torsion zone that makes them suitable for use with power tools and impact drivers while providing up to 120× longer life compared to Wiha standard bits. A fluorescent coating with blue marking makes bits easier to locate, even in low light when using UV light, reducing loss and replacement costs. The hexagonal 1/4" shank ensures compatibility with standard bit holders and quick changes.

How to use

Select the T10 bit from the set and insert it into a compatible 1/4" hex bit holder, manual screwdriver handle, or power tool. Apply the appropriate torque for the fastener and material. When using impact drivers or power tools, the torsion zone will absorb peak loads to reduce stress on the bit and fastener. After use, store the bits in their holder or a designated case to keep the fluorescent coating clean for easy identification.

Recommendations

For best results, match the T10 bit precisely to T10 Torx screws, avoid excessive sideways force, and replace bits if the tip shows visible wear. Use UV light in low-light environments to locate the fluorescent-coated bits quickly and reduce loss and replacement costs.
