Wiha 41610 Screwdriver Bit Set

The Wiha 41610 screwdriver bit set contains five T40 Torx bits, each 25 mm long with a 1/4" (25.4 / 4 mm) hexagonal shank. Made in Germany, these bits are designed for use with hand tools, power tools and impact screwdrivers and are intended to simplify selection by matching only the screw shape. The set is suitable for fastening T-shaped screws with a 90° angle between the screw head and thread.

Advantages

Wiha’s patented torsion zone increases durability, providing up to 120× longer life compared with Wiha standard bits. The bits feature a fluorescent coating and blue marking that make them quick to locate, including under UV light, which reduces loss and lowers replacement costs. Their design allows reliable use with power tools and impact drivers while maintaining precision.

How to use

Select the appropriate T40 bit from the set and insert the 1/4" hex shank into your screwdriver or power tool chuck. When using power tools or impact drivers, ensure the bit is fully seated and apply steady pressure to maintain correct engagement with the screw head. After use, store bits in their case to protect the fluorescent coating and marking.

Recommendations

For longest service life, use the bits within their intended torque range and avoid excessive side loads. Inspect bits regularly for wear and replace if the tip becomes rounded or damaged. Use UV light when searching for lost bits in low-light conditions to take advantage of the fluorescent coating.
