Screwdriver Bit PH Wera PH 00 4 mm, Length 40 mm

Precision screwdriver bit Wera PH 00 4 mm, length 40 mm, is designed for driving Phillips PH00 fasteners in delicate assemblies. Made for use with bit holders and multi-bit screwdrivers, this bit provides a precise fit and consistent torque transfer for tasks in electronics, small appliances, and hobby projects. The compact 40 mm length gives controlled reach in confined spaces while maintaining stability during turning.

Advantages

The Wera PH 00 bit features hardened steel construction and a precisely machined Phillips tip for reduced cam‑out and reliable engagement with PH00 screws. Its 4 mm tip diameter and 40 mm overall length balance access and control, enabling accurate fastening without excessive intrusion into compact assemblies. The bit is compatible with common 1/4" hex bit holders and multi-bit screwdriver handles, allowing quick changes and secure retention during use.

Key specifications

• Tip type: Phillips PH00
• Tip diameter: approximately 4 mm
• Overall length: 40 mm
• Material: hardened tool steel (precision machined)
• Drive interface: 1/4" hex compatible

How to use

Insert the Wera PH 00 bit into a compatible 1/4" hex bit holder or multi‑bit screwdriver handle until it locks. Position the Phillips tip into the screw head and apply steady axial pressure while turning to engage the screw. For best results, ensure the tip fully seats in the screw recess before applying torque and avoid excessive force to reduce wear and risk of damaging the screw or bit.

Recommendations

Use the bit for low to moderate torque applications typical of electronics and small appliances. Replace the bit if the tip shows rounding or wear. Store in a dry place and keep free from debris to maintain accurate fit and prolong service life.
