Screwdriver Bit Wiha 41636 5 pc(s) Torx T40

The Wiha 41636 set contains five Torx T40 screwdriver bits, each 50 mm long with a 1/4" (6.35 mm) hex shank. Designed for precision fastening, these bits combine a fluorescent yellow marking for quick identification and a torsion-optimised geometry for extended service life. The set is lightweight and suitable for both manual and powered use where a Torx T40 bit is required.

Advantages

Fluorescent yellow marking makes individual bits quick and easy to find, including in low-light conditions when used with a UV light. The optimised bit geometry with a patented torsion zone increases durability and offers up to 120× longer lifespan compared to Wiha standard bits for the corresponding screw shape. The bits are suitable for use with power tools and impact screwdrivers, reducing downtime and replacement frequency.

• Fastening Torx T40 screws
• Use with manual screwdrivers that accept 1/4" (6.35 mm) hex bits
• Use with power tools and impact drivers that accept 1/4" (6.35 mm) hex bits

How to use

Select a Torx T40 bit from the set and insert the 1/4" hex shank into the compatible screwdriver handle, bit holder or power tool chuck. Engage the bit fully with the screw head to ensure correct seating before applying torque. For powered or impact use, set the tool to appropriate torque settings and apply steady pressure to avoid cam-out. After use, store bits in their holder or a dry, organised place to maintain visibility of the fluorescent marking.

Usage recommendations

Use the fluorescent-marked bits to speed up identification in busy toolboxes or dimly lit environments; inspect bits regularly for wear and replace when tip wear affects engagement. Do not use damaged bits, and match the Torx T40 tip precisely to the screw to avoid damage.
