Plastic Screw Property

This page describes "Plastic Screw Properties" such as PEEK, PTFE (Teflon), PPS, PC (polycarbonate) and PP (polypropylene).

Small screws are required 【Compact / lightweight】

Introducing a rich lineup of miniature screws and precision screws.

Screws with high strength are required even in environments where steel cannot be used 【Compact / lightweight】

Introducing screws using stainless steel/titanium screws with strength equivalent to steel for space and weight saving.

Screws must be protected from chemicals 【Energy-saving / reduced work-hours】

Introducing screws with excellent chemical resistance and screws with head coatings.
