Screwdriver Bit Wiha 41643 5 pc(s)

The Wiha 41643 screwdriver bit set contains five Torx T10 bits, each 50 mm long with a 1/4" hexagonal shank. Made in Germany, these bits are designed for precise engagement with T-shaped screws and secure fitment in hand and power tools. The set follows Wiha's bit concept where the screw profile determines the correct bit, and the bits incorporate a patented torsion zone that makes them suitable for use with impact screwdrivers and power tools.

Advantages

These Wiha Torx T10 bits feature an optimised design for T-shaped screws and a patented torsion zone that increases durability and allows safe use with power tools and impact drivers. A fluorescent, blue marking makes the bits easy to find, even under UV light, reducing loss and lowering replacement costs. Compared with standard Wiha bits, the specialised torsion design provides a significantly longer service life.

Suitable for

• Fastening and removing T10 Torx screws in electronics and appliance assembly
• Use with 1/4" bit holders, manual handles and power/impact drivers
• Workshop, maintenance and professional installation tasks

How to use

Select a T10 bit from the set and insert the 1/4" hex shank into the bit holder, screwdriver handle or power/impact driver. Engage the bit fully with the T-shaped screw head to ensure correct seating before applying torque. Use controlled torque appropriate to the workpiece and fastener to avoid cam-out or damage.

Usage recommendations

For extended bit life, avoid using excessive torque settings and inspect bits regularly for wear. Use the fluorescent marking and UV light to locate lost bits quickly; replace any bit that shows visible deformation or rounding of the tip.
