METRIC
AND SELF-FORMING SCREWS

Metric and self-forming screws for every need

Metric and self-forming screws production.
We can combine every type of head and rod mark with the desired thread.
For ISO metric threads, the ideal screw and female screw profiles coincide.
The lead and the pitch of the thread are the same.

METRIC SCREWS


Available metric threads:

- ISO
- ASA(UNC)
- ASA(UNF)
- whitworth (bsw) from M 1.6 mm to M 9 mm maximum length 90 mm
- Screws with self-forming metric thread
- Trilobular
- Self-tapping

Tipsgrow:

Used to form a metric thread into metallic materials such as steel, copper and alloys, aluminum and alloys. During the screwing operation into smooth holes, the screw forms its threaded seat providing a superior sealing and a more precise coupling than any other screw tightened into threaded female screws. These types of screws can be unscrewed and other normal metric ISO thread screws can be screwed into the same seat.

Materials:

- Screw steel 4.8 - 5.8 - 8.8 - 10.9
- Brass
- Aluminum
- Copper
- Stainless steel
