DIN 931 is the product standard for these hexagon bolts. BS EN ISO 898-1 provides the mechanical-properties reference for metric steel bolts, screws and studs with specified property classes. Please contact us before ordering to confirm compliance certification availability.
Self colour steel has no zinc-plated protective finish. Consider suitable corrosion protection where the fasteners will be exposed to moisture. Check that the threaded and unthreaded lengths suit your assembly, and select compatible nuts and washers.
