Sheet Metal Thread Forming

Thread rolling is a metal rolling process used extensively in manufacturing industry to produce screws bolts and other fasteners.

Sheet metal thread forming.

A common thread rolling process used in industry to manufacture threaded parts involves forming the threads into the metal of a blank by a pressing and rolling action between two die. Steel rounded head blunt screws for sheet metal. Type 25 thread cutting a thread cutting screw similar to type 23 point except with type b thread. These steel screws are zinc plated to resist corrosion in wet environments.

Thread cutting screws have tapered entering threads and multiple cutting edges to dig into the boss tapped hole. 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. 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. Often referred to as type b thread forming screws they require a drilled hole and are typically used in 0 050 0 200 material.

Both are a type of self tapping screw.
