Screwdriver Bit Wiha 41624

The Wiha 41624 screwdriver bit set contains five PH 1 Phillips bits, each 50 mm long, designed for use with a 1/4" shank holder. Manufactured by Wiha, these bits are intended for precision fastening tasks where reliable engagement and efficient torque transfer are required. The set suits handheld bit drivers, interchangeable-bit screwdrivers and bit holders used in both manual and low-speed power tool applications.

Advantages

The bits are made to provide consistent tip geometry for reduced cam‑out and secure seating in Phillips fasteners. Their 50 mm length balances access into recessed screwheads with control during operation. The standardized 1/4" shank ensures compatibility with common bit holders and magnetic adapters. Components are engineered for durability and repetitive use in general assembly, maintenance, and repair tasks.

How to use

Select a PH 1 bit from the set and insert the 1/4" shank into a compatible bit holder or screwdriver. Position the Phillips tip fully into the screw recess to ensure correct engagement, then apply steady axial pressure while turning the driver to drive or remove the screw. For recessed or hard-to-reach screws, use the full 50 mm length to gain access while maintaining control. Inspect tips regularly for wear and replace if the geometry degrades to avoid slipping or rounding fastener heads.

Recommendations

Use the bits with appropriate torque settings when using powered drivers to prevent tip damage and fastener stripping. Store the set in a dry place and keep bits clean of debris. Replace bits that show visible wear or damage to maintain fastening reliability and protect screw heads.
