Phillips Machine 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.
Phillips drive is similar to Pozi Drive (type Z).
Head Styles
Pan Phillips
The pan head is cylindrical head with a slightly rounded top surface and a flat bearing surface underneath. This head style is ideal for most applications where a protruding head is acceptable.
