Screwdriver Bit Set Wiha 41600

The Wiha 41600 screwdriver bit set contains five Phillips PH3 bits, each 25 mm long with a 1/4" (25.4 / 4 mm) hexagonal shank. Made in Germany, these bits are designed for precise engagement with PH3 screw heads and for use with common hand and powered drivers that accept 1/4" bits.

Advantages

The Wiha bits follow a simplified selection concept where only the screw shape determines the correct bit. Each PH3 bit features a patented torsion zone that allows safe use with power tools and impact drivers and provides a significantly longer service life compared to Wiha standard bits. The bits have a coloured fluorescent coating that makes them easier to locate, including under UV light, reducing loss and replacement costs.

Suitable for

• Driving PH3 Phillips screws in wood, metal and plastic
• Use with 1/4" bit-holders, ratchets and power drivers
• Professional and DIY fastening tasks requiring durable bits

How to use

Select a PH3 bit for screws with a Phillips PH3 recess, insert the 1/4" hex shank into the driver or bit holder until it seats, and operate at the appropriate speed and torque for the screw material. The torsion zone tolerates shock loads from impact drivers, but adjust torque and feed to avoid cam‑out and premature wear. Inspect bits before use and replace if deformed.

Usage recommendations

Store bits in a dry place and keep them in a bit holder or case to avoid loss. Use the fluorescent coating and UV light in low‑light environments to locate bits quickly. Match the PH3 size to the screw recess and avoid excessive torque to extend service life.
