What is PN Fasteners?

PN Fasteners are bolts, screws, nuts and washers manufactured to Polska Norma (PN) specifications, published by the Polish Committee for Standardization (PKN) and closely harmonised with EN and ISO metric practice. PN specifications define precise tolerances for thread pitch, head geometry, drive type and material property class, making PN fasteners a trusted reference for Polish and Central European engineering projects. Sterling Fasteners manufactures the complete PN catalogue — hex bolts, hex nuts, washers and structural fasteners — under a single quality management system, giving buyers one supplier for an entire PN 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 PN size or a mixed container of several PN standards, our export team consolidates documentation, packing lists and mill certificates into one shipment.
