Conjunto de bits para chave de fendas Wiha 41612 5 unid.

The Wiha 41612 5-piece screwdriver bit set contains five 4 mm hex (metric) bits, each 25 mm long, with a 1/4" hexagonal shank. Manufactured in Germany, the set is designed so the screw head profile alone determines bit selection. The T-shaped bit concept and patented torsion zone make these bits suitable for manual and power tool use, including impact drivers, while improving durability and findability through a fluorescent coating.

Advantages

The bits feature a patented torsion zone that increases service life by up to 120× compared to Wiha standard bits. Colour marking and a fluorescent coating make bits quicker to locate, even in low-light when using UV light. The hex shank ensures secure fit in standard 1/4" bit holders and drivers, supporting both precision and power applications.

Key specifications

How to use

Insert a 1/4" hex bit into a compatible bit holder, screwdriver or power driver. Select the bit matching the screw head profile and seat it fully in the fastener before applying torque. The torsion zone allows safe use with impact drivers; however, ensure correct bit alignment to avoid cam‑out and premature wear.

Recommendations

Store bits by colour or type to speed up selection; use UV light in dim conditions to locate fluorescent markings. Replace bits when signs of wear or deformation appear to maintain fastening quality and avoid damage to screws.
