Fasteners

Our fasteners range covers bolts and nuts to DIN standards for reliable joints in mechanical engineering, assembly, vehicle workshops and the home workshop. Choose coarse and fine threads in steel, stainless steel A2/A4 and brass, across a range of strength classes – all backed by large stock and fast delivery.

Start with the thread size and pitch (e.g. M8, M10, coarse or fine) and the DIN standard that defines the shape and dimensions. DIN 931 and DIN 933 bolts pair easily with DIN 934 nuts, while axles and vibration-prone joints use DIN 935 and DIN 937 castle nuts or DIN 985 nylon-insert lock nuts.

Pick the material to suit the conditions: class 8 or 10.9 steel for high loads, zinc-plated steel for added protection, and stainless A2 and A4 for damp or outdoor use. For special applications you will also find DIN 912 and DIN 7991 socket screws, countersunk screws and DIN 6921 flange bolts.
