Sheet Metal Thread Forming

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

Sheet metal thread forming.

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. Thread form creates a complete self locking fastening system that holds the screws more tightly with metal tension thereby reducing vibration cutting assembly costs and increasing productivity. They have a five edged shank that presses tightly against the material to form threads and resist loosening. Often referred to as type b thread forming screws they require a drilled hole and are typically used in 0 050 0 200 material.

Length is measured from under the head. These steel screws are zinc plated to resist corrosion in wet environments. Steel rounded head blunt screws for sheet metal. Thermoplastics with a higher flexural modulus also allow the formation of threads but usually require a fastener with a low helix angle to avoid excessive drive torque.

You could look at using sheet metal screws that cut their own threads. Thread form punch die button units. 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. Plastics with a high flexural modulus including thermosets are too stiff for thread forming and will require thread cutting fasteners.

Thread cutting screws have tapered entering threads and multiple cutting edges to dig into the boss tapped hole. Also known as tap flex screws these are made from hardened steel to penetrate hard material.
