Sirius Set Screws A4 316 Stainless Steel

Sirius Set Screws in A4 316 stainless steel are premium fully threaded fasteners built for demanding marine, engineering and industrial environments where corrosion resistance is critical. Manufactured from A4 316 grade stainless steel, they deliver outstanding protection against rust, saltwater and aggressive chemicals — making them the go-to choice for coastal, offshore and outdoor installations.
