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.
