Screwdriver Bit Wiha 41613 5 pc(s)

The Wiha 41613 screwdriving bits set contains five 5 mm hex (metric) bits with a 25 mm working length and a 1/4" (25.4 / 4 mm) hex shank. Manufactured in Germany, these bits are designed for durable, precise fastening and are compatible with hand drivers, bit holders and many power tools. The set follows Wiha's bit concept where the screw shape determines the correct bit; the T-type profile is highlighted for T-shaped screws and benefits from an optimized design and torsion zone for extended life.

Advantages

The bits feature a patented torsion zone that allows safe use with power tools and impact drivers while reducing breakage and wear. A fluorescent coating and blue marking make bits easier to find, including under UV light, which decreases loss and replacement costs. Compared to standard Wiha bits, the optimized bits provide a significantly longer service life.

How to use

Select the 5 mm hex bit and insert it into a compatible 1/4" bit holder, manual screwdriver or power driver. For power or impact use, ensure the tool settings and torque are appropriate for the fastener and material. Replace worn bits when fit or performance degrades; the torsion zone reduces the risk of sudden breakage but does not eliminate normal wear.

Recommendations

Store bits in a designated holder to keep the fluorescent coating visible and reduce loss; inspect bits before use and avoid excessive side loading to prolong service life.
