Detail & Specs
Self-Tapping screws are meant to be installed directly into sheet metal. Tapping Screws require a pilot hole and tap their own threads during install.
They cannot be used with machine thread tapped holes or machine thread nuts.
Flat head tapping screws have a 90 degree angled head profile in order to sit flush with countersunk holes. The length of flat head countersunk screws is always measured from the top of the head (overall length).
Stainless tapping screws are commonly used in damp or wet environments for corrosion resistance, popular across a wide range of industries: furniture, automotive, industrial machinery, architectural finish work, agriculture, food processing, clean energy, etc.
For any application involving marine (salt water), use A4 / 316 Stainless Steel material, available as a special order.
