Thread forming screw for plastic pt screws for plastic tapping screws

Thread forming screw for plastic are generally for applications where large internal stresses are permissible, or desirable, to increase resistance to loosening. Many different thread forming screws are available to lower assembly costs by solving application problems such as eliminating the need to drill and tap panels. These can be broadly categorized into thread forming screws for metal and thread forming screws for plastic. Ever Hardware provides custom made thread forming screw for plastic and customizable packaging.

The Phillips screw drive was created by John P. Thompson, who after failing to interest manufacturers, sold his design to businessman Henry F. Phillips. Phillips is credited with forming a company (Phillips Screw Company), improving the design, and promoting the adoption of his product. The original patent expired in 1966, but the Phillips Screw Company continued to develop improved designs.
Phillips drive bits are often designated by the letters “PH”, plus a size code 0000, 000, 00, 0, 1, 2, 3, or 4 (by order of increasing size); the numerical bit size codes do not necessarily correspond to nominal screw size numbers.

Zinc coatings prevent oxidation of the thread forming screw by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate’s surface integrity as it is formed. Indeed, the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
