What is DIN Fasteners?

DIN Fasteners are bolts, screws, nuts and washers manufactured to the dimensional and mechanical standards set by DIN (Deutsches Institut für Normung), the German national standards body. These specifications define exact tolerances for thread pitch, head geometry, drive type and material property class, making DIN fasteners a globally recognised benchmark for engineering interchangeability. Sterling Fasteners manufactures the complete DIN catalogue — socket head cap screws, hex bolts, hex nuts, washers and specialty fasteners — under a single quality management system, giving buyers one supplier for an entire bill of materials. Our production facility runs cold-forging and CNC threading lines dedicated to metric fasteners, supported by an in-house metallurgical lab for batch testing. Whether you need a single DIN 912 size or a mixed container of ten different standards, our export team consolidates documentation, packing lists and mill certificates into one shipment.
