Thread forming screws for plastic metal galvanizing torx cap screws

Thread forming screws 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 screws for plastic and customizable packaging.

Torx screws are commonly found on automobiles, motorcycles, bicycle brake systems (disc brakes), hard disk drives, computer systems and consumer electronics. Initially, they were sometimes used in applications requiring tamper resistance, since the drive systems and screwdrivers were not widely available; as drivers became more common, tamper-resistant variants, as described below, were developed. Torx screws are also becoming increasingly popular in construction industries.

Galvanization, or galvanisation, (or galvanizing as it is most commonly called in that industry), is the process of applying a protective zinc coating to steel or iron, to prevent thread forming screws rusting. The most common method is hot-dip galvanizing, in which parts are submerged in a bath of molten zinc. Galvanizing protects in three ways:
It forms a coating of zinc which, when intact, prevents corrosive substances from reaching the underlying steel or iron.
The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
The zinc protects its base metal by corroding before iron. For better results, application of chromates over zinc is also seen as an industrial trend.
