Phillips MC SCREWS
CROSS RECESSED MACHINE SCREWS
The Phillips screw drive (specified as an ANSI Type I Cross Recess and type H in ISO documentation) is among the most popular drive style for screws.
Cross recess H (Phillips) according to ISO 4757
- Has a conventional cruciform recess with all walls inclined, the end of the screwdriver having trapezoid webs.
- The general dimensions are given in the product information of the respective catalogue group.
The design is often criticized for its tendency to cam out at lower torque levels than other “cross head” designs.

- Check tapped hold with thread plug gauge to ensure correct fit.
- Do NOT over-tighten. Keep the tightening torque to about 80% of the recommended torque for best results. Use a Torque adjustable driver.
