Screwdriver Bit Set Wiha 42108

The Wiha 42108 screwdriver bit set contains five Torx T10 bits, each 29 mm long with a 1/4" (6.35 mm) shank. These compact bits are designed for precision fastening tasks and are compatible with a wide range of screwdrivers and bit holders. The set combines a universal screw-shape concept with Wiha's torsion technology to deliver increased durability and suitability for both manual and powered impact use.

Advantages

The TY-style bits work with both T-shaped and Y-shaped screws, reducing the need to select bits based on screw or tool type. A patented torsion zone protects the tip during torque peaks, making the bits suitable for power tools and impact screwdrivers and extending service life compared to standard bits. Fluorescent coloured coating improves visibility and helps locate bits quickly, even under UV light.

How to use

Select a Torx T10 bit from the set and insert the 1/4" shank into the screwdriver, bit holder or power tool chuck. Ensure the bit seats fully in the screw head before applying torque. For powered or impact drivers, use controlled settings and allow the torsion zone to absorb torque peaks. Replace worn bits to maintain optimal screw engagement.

Recommendations

The bits are intended for Torx T10 screws and compatible TY/Y-shaped applications. Use appropriate torque settings for power tools, store bits in a dry location, and make use of the fluorescent coating and UV light if available to locate misplaced bits quickly.
