Overview
Stainless steel and mild steel hexagonal bars (hex bars) are used to manufacture fasteners, machine keys, fittings and components that need a six-sided grip. Cold-drawn hex bars offer excellent dimensional accuracy and surface finish — making them ideal for further machining.
We supply hex bars in a full range of sizes and grades. Standard AF (across-flats) sizes from 8 mm to 75 mm are usually ex-stock. Larger sizes and special grades can be indented.
Common grades
