What is BS Fasteners?

BS Fasteners are bolts, screws, nuts and washers manufactured to specifications published by the British Standards Institution (BSI), the United Kingdom’s national standards body. BS specifications define precise tolerances for thread form, head geometry, drive type and material property class, making BS fasteners a trusted benchmark across UK and Commonwealth engineering projects. Sterling Fasteners manufactures the complete BS catalogue — hex bolts, hex nuts, washers and black bolts — under a single quality management system, giving buyers one supplier for an entire BS bill of materials. Our cold-forging and CNC threading lines are dedicated to metric and BS-specification fasteners, supported by an in-house metallurgical lab for batch testing. Whether you need a single BS 3692 size or a mixed container of several BS standards, our export team consolidates documentation, packing lists and mill certificates into one shipment.
