Exafast is now the sole distributor of Genuine Nyloc nylon insert lock nuts.

Genuine Nyloc nuts are professionally presented and conveniently packed in retail carton quantities. Exafast’s stocked range of Genuine Nyloc nuts is extensive and includes:

  • Metric in Class 5 and Class 8
  • UNC and UNF in Grade 2, Grade 5 and Grade 8
  • BSW in mild steel
  • Finished in either zinc dichromate plating or hot-dip galvanising; for superior corrosion resistance

By offering true high tensile nuts, in addition to the commonly available mild steel, Exafast offers the ability to correctly match nut grades to bolt grades. This is critical in applications, where bolt pretension cannot be compromised. Mild steel can still be selected for use with lower specification bolts or where price is the primary consideration.

Genuine Nyloc nuts are manufactured to the stringent of standards, with every batch extensively tested by the manufacturer and again by Exafast at its own state-of-the-art fastener testing laboratory. Every aspect of the nuts is carefully examined; from basic physical dimensions to mechanical properties.

In addition to the stringent strength specifications, all Genuine Nyloc nuts meet the prevailing torque requirements of ISO 2320 (metric) or IFI-100/107 (UNC/UNF). Prevailing torque is a critical measure of the locking ability and reusability of a lock nut, yet is often overlooked by manufacturers of inferior products.
