Screwdriver Bit Phillips PH1 1/4" x 37 mm Proline (58135)

Proline Screwdriver Bit Phillips PH1 1/4" x 37 mm is a cross-tip (Phillips) bit engineered for use with manual screwdrivers, powered drivers and bit holders. The PH1 profile matches standard PH1 screws commonly used in furniture assembly, electrical fixtures and general repair work. With a 1/4" hex shank and a 37 mm working length, the bit provides compatibility with a wide range of drivers and adapters while offering access into shallow recessed screw heads.

Advantages

The bit is manufactured from durable steel to withstand repeated use and maintain tip geometry for consistent engagement with PH1 screws. The 1/4" hex shank ensures secure seating in chucks and quick-change holders, reducing wobble and improving torque transfer. Its 37 mm length balances reach and control for both handheld and powered applications.

Suitable for

• Furniture assembly and mounting hardware
• Electrical and electronics installation tasks
• General household repairs and maintenance
• Use with manual screwdrivers, cordless drivers and bit holders

Key specifications

• Tip type: Phillips (cross) PH1
• Shank: 1/4" hex
• Overall working length: 37 mm
• Material: heat-treated steel

How to use

Select the PH1 bit for screws that match the PH1 profile to ensure proper fit and minimize cam-out. Insert the 1/4" hex shank into the driver or bit holder until it seats firmly. Apply steady pressure and appropriate torque while driving or removing screws; when using powered drivers, start at low speed to confirm alignment, then increase speed as needed. Inspect the bit tip before use and replace it if the tip is rounded or damaged to avoid damaging screw heads.

Usage recommendations

For longer bit life, avoid excessive side loading and use the bit with drivers that match the required torque for the fastener. Store the bit in a dry place to prevent corrosion and keep spare PH1 bits available for frequent tasks.
