DIN 933 is the product standard for these hexagon set screws. 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. Select compatible nuts and washers to suit the strength and requirements of the assembly.
