Wiha 42110 Screwdriver Bits

The Screwdriver Bit Wiha 42110 is a set of Torx T20 bits with a 29 mm length and a total weight of 58 g. Designed to provide durable, precise engagement with T-shaped fasteners, the bits use Wiha's patented torsion zone and fluorescent coating to extend service life and improve visibility in low light conditions.

Advantages

The Wiha 42110 reduces replacement costs by offering a significantly longer lifespan compared to standard bits and makes bits easier to locate thanks to red marking and a fluorescent coating that is visible under UV light. The patented torsion zone increases durability and allows safe use with power tools and impact screwdrivers while maintaining precise fit and torque transfer.

How to use

Select a T20 bit from the Wiha 42110 set and insert it into the appropriate bit holder or screwdriver. Ensure the bit seats fully in the screw head to prevent cam-out. For power-tool use, engage the tool at the recommended speed and torque settings for the fastener and material. After use, store bits in a dedicated holder or the original packaging to maintain the fluorescent coating and reduce loss.

Recommendations

Use the Wiha 42110 bits for T20 applications and inspect bits regularly for wear; replace if the tip shows rounding. For best visibility in dark conditions, illuminate with a UV light to locate the fluorescent red-marked bits.
