Set de biți Wiha 41590

The Wiha 41590 screwdriver bit set contains five Pozidriv PZ 3 bits, each 25 mm long, with a 1/4" hexagonal shank designed for secure fitting in power tools. Made in Germany, the set is intended for accurate fastening tasks and offers a specialist solution for T-shaped and similar screw head profiles when paired with compatible screws.

Advantages

Wiha's bit concept simplifies selection by focusing on screw shape rather than tool or fastening type. The bits include a patented torsion zone that allows use with power tools and impact drivers while extending service life significantly compared to standard bits. A fluorescent coating and blue marking make the bits easier to locate, including under UV light, which reduces loss and replacement costs.

How to use

Select the PZ 3 bit and insert it into a compatible 1/4" hex holder or directly into the tool’s bit chuck. Ensure the bit seats fully before applying torque. The torsion zone permits use with both hand and powered impact drivers; start at low speed or torque setting when using a power tool and increase as needed to avoid damaging the fastener or workpiece.

Recommendations

Store bits in a designated holder or case and keep the fluorescent coating clean for optimal visibility. Replace bits when tip wear affects engagement. Use the bits with the intended Pozidriv screws and appropriate torque settings to maximize lifespan and maintain fastening quality.
