## Summary description

Screwdriver bit Rockforce PH4 in 5/16" size with a 30 mm length. Designed for Phillips (PH) fasteners, this interchangeable bit suits manual and powered drivers that accept standard bit shanks. Useful for assembly, maintenance and repair tasks requiring a PH4 tip and moderate reach in wood, metal and plastic applications.

## Long description

The Rockforce PH4 screwdriver bit in 5/16" size and 30 mm length is an interchangeable tip designed for driving Phillips (PH) fasteners. It fits standard bit holders and can be used with manual screwdrivers, quick-change bit holders and compatible powered drivers. The PH4 profile provides secure engagement with medium to large Phillips screws, while the 30 mm length gives moderate reach for recessed or partially obstructed fasteners in wood, metal and plastic assemblies.
Advantages
This Rockforce PH4 bit combines a precisely formed Phillips tip with a robust shank to maintain alignment and reduce cam-out during driving. The 5/16" cross-section ensures compatibility with tools that accept standard hex or slotted bit formats, and the 30 mm length balances access and control for general assembly and repair tasks. Its solid construction is intended to provide consistent tip geometry and a predictable fit with PH4 screws.
Suitable for
Assembly of furniture and fixtures requiring PH4 fasteners
Maintenance and repair tasks on metal, wood and plastic components
Use with manual screwdrivers, quick-change holders and compatible power drivers
Situations requiring moderate reach into recessed screw locations
Key specifications
Screwdriver tip type: Phillips (PH4)
Shank/cross size: 5/16"
Overall bit length: 30 mm
Interchangeable bit for standard bit holders and drivers
Material: hardened steel construction (standard for impact and general driving use)
How to use
Select the Rockforce PH4 bit and insert it securely into the bit holder or driver chuck. Position the tip into the Phillips screw recess, apply steady axial pressure to keep the tip engaged, and drive the screw at an appropriate speed or torque for the material. For manual use, maintain alignment between driver and screw; for powered drivers, use controlled speed and torque settings to avoid stripping the screw head or damaging the bit.
Usage recommendations
Use the PH4 bit for medium to large Phillips screws and avoid excessive torque beyond the bit or screw rating. Inspect the tip before use; replace the bit if the tip shows rounding or wear to ensure reliable engagement and to reduce the risk of cam-out.
