 Three Popular Screw Drive Types

Three Popular Screw Drive Types

The screw drive is a set of shaped cavities and protrusions on the screw head that allow torque to be applied to it.  It should be noted that the different drive types determine not only the torque of screwing in, but also the tightening tool used. The following are some of our company’s most popular drive types:

1.Phillips Drive

The Phillips drive screw were originally developed and improved by the Phillips Screw Company.

Though from 1966 the patent of the company expired, the term “Phillips” is still used to refer to this drive style.

It is characterized by a cross-shaped drive on the screw head. The Phillips countersunk head screws are generally used in mechanical equipment, household appliances, digital products, decoration and construction, etc.

2.Pozi Drive

Pozi drive, often abbreviated as PZ or PSD, are characterized by a beige shape on the screw head.

Pozi drive are basically designed like the Phillips drive, with a set of radial indentations at 45° to the main cross drive in the screw head.

Compared to Phillips drives, the pozi drive can handle higher torques without damaging the groove.

3.Torx Drive

Torx drive, also known as star drive, are characterized by a 6-point star-shaped pattern.

Torx was originally a screw trademark developed and marketed by Camcar Textron in 1967, and later people continued to use this name to refer to it.

Torx screws are often used in brake systems of automobiles, motorcycles, bicycles, and electronic products, etc.
