Single wiha screwdriver bit with a Phillips PH3 profile and 29 mm length, made from molybdenum-vanadium steel for enhanced durability. The bit is intended for driving and removing PH3 screws in assembly, maintenance and repair tasks. Its compact dimensions fit standard bit holders and impact drivers and provide reliable tip strength and wear resistance for professional and DIY applications.

Advantages

The molybdenum-vanadium steel construction improves toughness and reduces wear during repeated use. Precise Phillips PH3 geometry ensures good fit in matching screw heads, minimising cam-out. The 29 mm length balances accessibility in confined spaces with sufficient engagement for safe screw driving. Compatible with common 1/4" hex bit holders and impact-ready drivers.

Key specifications

How to use

Insert the bit into a compatible 1/4" hex bit holder or impact driver and ensure it seats securely. Align the PH3 tip with the screw head and apply steady axial pressure while turning the driver to avoid cam-out. For removal, reverse the rotation while maintaining alignment. Inspect the bit tip for wear and replace when the profile is rounded or damaged.

Recommendations

Use appropriate torque settings on power drivers to prevent tip damage and avoid excessive force that can deform screw heads; store bits dry and clean to maintain corrosion resistance.
