Screwdriver Bit Proline PH3 1/4" x 37 mm — Phillips Cross Tip

Proline PH3 Phillips screwdriver bit with a 1/4" hex shank and 37 mm length is engineered for engagement with PH3 cross-recess screws. Manufactured to fit standard 1/4" bit holders and power drivers, this Proline bit provides a precisely shaped tip to reduce cam-out and ensure consistent contact with Phillips fasteners during assembly, repair, and construction work.

Advantages

The bit's PH3 tip geometry is produced to maintain accurate fit with corresponding screws, improving torque transfer and reducing wear on both the screw head and the bit. The 1/4" hex shank enables secure retention in quick-change chucks and manual bit holders, while the 37 mm overall length balances reach and control for general-purpose tasks. The bit is compatible with both manual and powered screwdrivers, offering versatility for different work environments.

Suitable for

• Installing and removing PH3 Phillips screws in furniture assembly
• Electrical and mechanical repairs requiring PH3 fasteners
• Construction and finishing tasks where Phillips PH3 screws are specified
• Use with cordless drivers, impact drivers (where recommended), and manual bit holders

Key specifications

• Tip type: Phillips PH3 (cross-recess)
• Shank: 1/4" hex for quick-change compatibility
• Length: 37 mm overall
• Compatible with: standard 1/4" bit holders and power drivers

How to use

Insert the 1/4" hex shank into a compatible bit holder or driver chuck until it locks. Align the PH3 tip with the screw recess and apply steady axial pressure while turning the driver to prevent cam-out. For powered drivers, select an appropriate speed and torque setting for the screw material to avoid overdriving. After use, store the bit in a holder or case to protect the tip profile.

Usage recommendations

Use the bit with drivers that accept 1/4" hex bits and match torque settings to the screw and material. Inspect the tip for wear before precision tasks and replace if the tip shows rounding or deformation to maintain secure engagement with PH3 screws.
