Screwdriver Bit Set Wiha 41645

The Wiha 41645 screwdriver bit set contains five T20 Torx bits, each 50 mm long and designed for fastening T-shaped (Torx) screws. The bits feature a fluorescent, blue-marked coating that makes them easier to locate — even in low light when using a UV light — and are suitable for use with power tools and impact screwdrivers.

Advantages

The optimized Torx bits deliver a significantly longer service life compared to Wiha standard bits, offering up to 120× greater lifespan thanks to a patented torsion zone. The fluorescent blue marking improves visibility and reduces time spent searching for bits, while the robust design reduces the frequency of replacements and lowers overall costs.

How to use

Select the T20 Torx bit from the set and insert it securely into your screwdriver, bit holder or power tool chuck. Ensure the bit is seated correctly before applying torque. When using power tools or impact screwdrivers, operate at the manufacturer-recommended settings and use appropriate torque control to avoid cam-out or screw damage. After use, store bits in their case or a marked compartment to maintain the fluorescent coating and ease of identification.

Recommendations

For longest service life, match the T20 Torx bit to the correct screw size, avoid excessive lateral forces, and use suitable torque settings on power tools. To quickly locate bits in dim environments, illuminate with a UV light to make the fluorescent blue marking visible.
