Big round washer head self-tapping screw manufacturer
Description
Big round washer head self-tapping screw manufacturer in China. The Phillips screw design was developed as a direct solution to a number of problems with slotted screws: too-easy cam out; precise alignment required to avoid slippage and damage to driver, fastener, and adjacent surfaces; and difficulty of driving with powered tools. Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (in order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.
A round head with the addition of an integrated flange at the base of the head. This eliminates the need for a flat washer. A self-tapping screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal or hard plastics, the self-tapping ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap.
