SS 316 Screws - Machine, Wood & Self-Tapping

SS 316 Screws are versatile threaded fasteners used across nearly every industry where a secure, non-permanent joint is required. The key advantage of the grade 316 alloy is the inclusion of molybdenum, which dramatically improves its resistance to pitting and crevice corrosion, especially when exposed to salt water or chloride-containing chemicals. This makes it the superior marine grade choice. Our comprehensive range includes Machine Screws (for pre-tapped holes), Wood Screws (for timber applications), and self-tapping screws. Zeron Fasteners specializes in manufacturing and supplying high-quality SS 316 Screws that deliver superior torque and thread reliability, ensuring long-term integrity in boat building, chemical equipment, exterior architectural work, and other highly corrosive environments.
