Thread rolling is cold metal or cold forming process that produces threads by the means of precision thread rolling dies that are the replicated image of the thread generation. This a different process from others such as grinding, chasing and cutting since it does...

Self-tapping screws create threads on their own as they enter into a material such as plastic. In fact, self-tapping screws with a special profile are required since the tapping screws commonly used with steel can cause residual stresses in plastic that can reduce the...

There are various challenges involved with fastening screws into a plastic material. The challenges revolve around joint failure issues related to stress relaxation, loss of clamping, load, and stripping. At ITW Shakeproof Industrial, we are your source standard and...

Due to the unique properties of plastic, the screws used to make connections in this material must also have special properties. The process of threading plastic with a screw is different than threading wood with a screw. It takes the right screw to penetrate the...

A thread forming screw refers to a screw that develops its own threads as it is driven into a mating material. Thread forming screws eliminate the need for a taping operation or nuts, which reduces the parts used and saves money. Steel and stainless steel thread...

Fastening screws into plastics can present multiple challenges. One wonder why due to the generally softer nature of plastic material compared to harder steel, but there are some joint failure considerations related to stripping, loss of clamping load, and stress...

Sheet metal screws are designed for use with sheet metal. The exterior threading of these screws covers their entire shank unlike a conventional screw which has only partial threading coverage of the shank – the threading starts part way up the shank of the...

Self-tapping screws develop their own threads as they penetrate into and below the surface of a material. Screws used to drill into plastic require a uniquely designed profile to ensure the structural integrity of the assembly is not damaged. Tapping screws designed...

Standard or metric thread forming screws for plastic, sheet metal, or wood are ideal when there is not a threaded hole in the location you would normally want one. With a thread forming screw, there is no requirement to set up a tap to produce female-threaded holes...

Tapping screws, acting upon materials into which they are driven, create mating threads in those materials. The two standard types of tapping screws are thread forming screws and thread cutting screws. At ITW Shakeproof...
