Screwdriver Bit Set Wiha 41628 5 pcs

The Wiha 41628 Screwdriver Bit Set contains five high-quality Pozidriv (PZ 2) bits, each 50 mm long with a 1/4" hex shank. Made in Germany, these bits follow Wiha's bit concept where screw shape alone determines bit selection. The set is designed for use with manual screwdrivers, power tools and impact drivers thanks to an integrated torsion zone and robust construction. Fluorescent coating and blue marking make the bits easy to locate, even in low light using a UV light.

Advantages

This bit set reduces tool costs through improved visibility and longer service life. The patented torsion zone increases durability—Wiha states up to 120× longer lifespan compared to their standard bits—while the fluorescent, blue-marked finish speeds up bit retrieval and reduces losses. The standardized PZ 2 geometry ensures precise engagement with Pozidriv screws.

Suitable for

• Installing and removing Pozidriv (PZ 2) screws
• Work with manual screwdrivers and bit holders
• Use with power tools and impact drivers due to torsion zone
• Jobs in workshops, maintenance and assembly where quick bit identification is useful

How to use

Select the PZ 2 bit from the set and insert it into a compatible 1/4" hex bit holder, screwdriver or power tool. For impact applications, the torsion zone absorbs shock to reduce bit breakage. Use the fluorescent coating and blue marking to quickly identify the correct bit; under UV light the coating becomes easier to see. Replace bits when wear affects fit or drive performance.

Usage recommendations

For best results, match the PZ 2 bit precisely to Pozidriv screw heads to avoid cam‑out. Use appropriate torque settings on power tools and inspect bits regularly for wear. The fluorescent marking aids recovery of lost bits in low-light conditions.
