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.
These screws have an oversized "truss" head style with an undercut bottom, low height rounded dome top and recessed phillips drive.
The flat bearing surface underneath the head covers a larger diameter than a typical pan head screw. This increased surface area reduces the chances of crushing or marring the material the screw is tightened against.
A truss-style head is the preferred design in applications where minimal clearance exists above the head. Suitable for license plates.
Stainless tapping screws are commonly used in damp or wet environments for corrosion resistance, popular across a wide range of industries: furniture, automotive (license plates), 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.
