Definition

Noun: A type of fastener with a threaded shaft and a distinctive recessed cross-shaped (+) pattern on its head, designed to be driven by a Phillips screwdriver. This design helps the driver bit to self-center and reduces the likelihood of it slipping out (cam-out) compared to a single-slot screw.

Usage

The term "Phillips screw" specifically refers to the screw itself, which is part of a matching system with a Phillips screwdriver. * You need a Phillips screwdriver to tighten that Phillips screw. * The assembly manual specifies using Phillips screws for the panel attachment. * I stripped the head of the Phillips screw by using the wrong size driver.

Advanced Usage

• The design is named after its inventor, Henry F. Phillips. The term is often used generically, though it is a trademarked name.
• In technical or manufacturing contexts, one might refer to the specific drive type as a "Phillips drive" or "cross-head drive."
