ScrewSourceCarbon Steel
Carbon steel screws supplied in two surface finishes: bright nickel plating for a clean decorative look, and black oxide for a low-glare, economical technical finish. The base steel is the same in both lines — the finish changes appearance and mild-corrosion behaviour, so stainless steel stays the choice for damp and outdoor use. Current lines cover self-tapping, machine, hex socket and screw-and-washer assemblies. Any specific size or grade depends on the item and is confirmed with your quotation.
