Wiha 41662 Screwdriver Bit Set 5 Pcs. Square 50 mm

Wiha 41662 screwdriver bits set contains five 50 mm square bits designed to make bit selection straightforward by focusing on screw shape. Each bit is coloured for easy identification and features a patented torsion zone that increases durability and allows safe use with power tools and impact drivers. The set aims to simplify fitting of square-headed screws while offering longer service life compared with standard bits.

Advantages

The patented torsion zone reduces stress on the bit during torque peaks, providing a significantly longer service life than Wiha standard bits. Coloured fluorescent coating improves visibility and quick identification, including under UV light. The bits are compatible with power tools and impact drivers due to the torsion design and are compact and lightweight for convenient handling and storage.

How to use

Select the square bit that matches the screw head size and insert it into the chuck or bit holder of your screwdriver or power tool. Ensure the bit is seated fully and engage the tool at the appropriate speed and torque settings for the material and screw size. For impact driver use, the torsion zone absorbs peak loads; nevertheless, check bit engagement frequently and replace the bit if it shows signs of wear or damage.

Recommendations

Use the Wiha 41662 square bits with correct-size screws and appropriate torque settings. Keep bits clean and store in a dry place. Use UV light for quick identification of fluorescent colours in low-light conditions. Replace bits when worn to avoid screw damage.
