Skruvbits-set Wiha 41606

The Wiha 41606 screwdriver bit set contains five T20 Torx bits, each 25 mm long, with a 1/4" hexagonal shank compatible with standard bit holders and screwdrivers. Made in Germany, these bits use Wiha's patented design including a torsion zone and fluorescent coating to improve durability and visibility. The set focuses on matching screw shape rather than tool type, making selection straightforward for fastening T-shaped screws with a 90° angle between thread and head.

Advantages

Wiha's revolutionary bit concept means that only the screw shape determines the correct bit. The torsion zone increases resistance to breakage and makes the bits suitable for use with power tools and impact drivers, offering up to 120× longer life than standard bits. The fluorescent, blue-marked coating improves visibility and allows quick location of bits even in low light when using UV light, reducing losses and replacement costs.

Key specifications

How to use

Insert a 1/4" hex shank bit into a compatible screwdriver, bit holder or impact driver. Select the T20 Torx bit for screws with a T-shaped recess and apply steady axial pressure while turning. For power tools or impact drivers, use appropriate torque settings and allow the torsion zone to absorb brief torque spikes to reduce wear.

Recommendations

Store bits in a designated case and use UV light in low-light environments to locate the blue fluorescent marking. Replace bits only when worn to maintain screw fit and avoid damaging fasteners; use correct torque settings when operating power or impact drivers.
