Sheet metal thread forming.

Both are a type of self tapping screw. Often referred to as type b thread forming screws they require a drilled hole and are typically used in 0 050 0 200 material. These steel screws are zinc plated to resist corrosion in wet environments. Thread rolling is a metal rolling process used extensively in manufacturing industry to produce screws bolts and other fasteners.

Use a thread cutting screw or a thread forming screw to create a tight fit in heavy gauge sheet metal aluminum cast iron and other hard materials. Larger root diameter with finer thread pitch for light and heavy sheet metal non ferrous castings plastics impregnated plywoods asbestos combinations and other materials. Steel rounded head blunt screws for sheet metal. Fastite 2000 screws feature a thread forming design created to deliver cost effective and optimum joint performance in sheet metal applications as thin as 0 7mm 028 in this unique design employs many of the design innovations for high performance thread rolling fasteners featured in taptite 2000 fasteners.

Type 25 thread cutting a thread cutting screw similar to type 23 point except with type b thread.
