Ruuvimeisselin kärkisarja Wiha 41650

The Wiha 41650 Screwdriver Bit Set contains five hex (metric) bits, each 3 mm in size and 50 mm in length, with a 1/4" (6.35 mm) hex shank for secure fitting. Made in Germany, this set is designed for precision fastening tasks and combines durability with compatibility for manual and powered screwdrivers.

Advantages

Wiha's bit concept simplifies selection by focusing solely on the screw shape; the T-bit included is designed for T-shaped screws with a 90° angle between thread and screw head. A patented torsion zone allows safe use with power tools and impact drivers while delivering a lifespan up to 120× longer than Wiha standard bits. The bits feature a blue fluorescent coating that makes them easy to locate, including under UV light, reducing loss and replacement costs.

How to use

Select the correct 3 mm hex bit and insert its 1/4" hex shank into a compatible bit holder, screwdriver or power tool. Use the bit to engage T-shaped or hex screws as appropriate; when using power tools or impact drivers, rely on the bit's torsion zone to absorb torque spikes. After use, store the bits in a secure case and, if needed, identify them quickly using a UV light to reveal the fluorescent coating.

Recommendations

For longest service life, avoid excessive side load and use the bits with properly fitted drivers. Inspect bits regularly for wear and replace only if visibly damaged. Use UV light in low-light environments to speed up retrieval and reduce replacement costs.
