Product overviewOverview
A Phillips recess transfers torque through four inclined faces, so contact is linear rather than areal and stress in the recess is higher than in a star drive. Tip size error makes it worse: oversize bottoms out in the recess, undersize contacts too far out, and both promote cam-out and raised burrs around the recess.
Material: S2 Alloy Steel. It is installed by 1/4-inch chuck on electric or pneumatic driver.
Key featuresFeatures
- PH000–PH3 coverage, matched strictly to the screw recess number.
- S2 steel quenched and tempered for hardness with torsional toughness.
- Tip angle ground to standard, reducing cam-out and burring.
- 1/4-inch hex shank for electric, pneumatic and hand drivers.
Typical applicationsApplications
- Appliance assembly and service
- Electronics production lines
- Furniture and hardware installation
Selection notesSelection
Match bit number to recess number; crossing sizes shortens the life of both bit and screw.
Frequently asked questionsFAQ
How do I specify the PH Phillips Screwdriver Bit?
What matters during installation of the PH Phillips Screwdriver Bit?
| Material | S2 Alloy Steel |
|---|---|
| Hardness | HRC58-62 |
| Drive | 1/4 inch hex shank |
| Sizes | PH000-PH3 |
| Standard | DIN 3126, ISO 8764 (cross recess) |
| Installation | 1/4-inch chuck on electric or pneumatic driver |

Tip thickness and width are checked on a profile projector against the PH standard.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
