Ponta de chave de fendas Wera Phillips PH PH1 6,3 mm, comprimento 89 mm

The Wera Kreuzschlitz-PH PH1 screwdriver bit with a 6.3 mm (1/4") hex shank and 89 mm overall length is a precision-machined insert designed for Phillips/Pozidriv PH1 fasteners. Its geometry ensures accurate engagement with screw heads to reduce cam-out and wear during assembly, maintenance and repair work. The 6.3 mm shank fits standard bit holders and quick-change chucks, while the extended 89 mm length provides better reach in recessed or confined spaces without sacrificing control.

Advantages

This PH1 bit offers precise tip geometry for secure seating in Phillips/Pozidriv PH1 screws, helping to minimize slippage and damage to fasteners. The 6.3 mm hex shank ensures compatibility with common bit holders, manual drivers and many impact drivers that accept 1/4" bits. The 89 mm overall length increases access to recessed screws and improves leverage in tight working conditions. Manufactured to consistent dimensions, the bit supports repeatable performance for professional and DIY tasks.

Suitable for

• Assembly of electronics, appliances and furniture using PH1 screws
• Maintenance and repair tasks in confined spaces or recessed fasteners
• Use with bit holders, quick-change chucks and compatible impact drivers
• General-purpose fastening where controlled torque and reduced cam-out are needed

Key specifications

• Type: Phillips/Pozidriv PH1 screwdriver bit
• Shank diameter: 6.3 mm (1/4" hex)
• Overall length: 89 mm
• Material: hardened tool steel (manufacturing standard)
• Tip geometry: optimized for PH1 fasteners to reduce cam-out

How to use

Insert the 6.3 mm hex shank into a compatible bit holder, quick-change chuck or driver. Position the PH1 tip squarely in the screw head to ensure correct engagement before applying torque. For manual drivers, apply steady axial pressure while turning; for powered drivers, select appropriate speed and torque settings to avoid overdriving or damaging the screw. After use, store the bit in a suitable holder or case to protect the tip and maintain dimensional accuracy.

Recommendations

Use the PH1 bit with screws of matching PH1 geometry and size; avoid forcing the bit into damaged or stripped screw heads. When using impact drivers, verify the bit and holder are rated for impact use. Regularly inspect the tip for wear and replace the bit if rounding or deformation is observed to maintain secure engagement and prevent fastener damage.
