Since 1996, HX has supplied the electrical construction industry with precision fastening components trusted in over 40 countries. Our Steel EMT Locknuts with grounding teeth represent the culmination of 27 years of metallurgical and manufacturing expertise — combining anti-vibration locking geometry with positive grounding continuity in a single, UL E345464 listed component.
Why Project Procurement Teams Choose HX Locknuts| Procurement Challenge | HX Partnership Advantage |
|---|---|
| Smooth-face locknuts loosen under sustained vibration from heavy machinery, HVAC equipment, and seismic activity. Loose connections cause arcing, overheating, and fire risk. | Patented serrated grounding teeth cut through paint and oxidation to establish direct metal-to-metal contact. Anti-vibration geometry mechanically locks against the enclosure surface. Maintains bonding integrity throughout the installation lifecycle. |
| Contractors spend additional labor installing separate bonding jumpers to meet NEC Article 250 grounding requirements — adding US$3-5 per connection in materials and time. | Built-in grounding teeth eliminate the need for separate bonding jumpers. One locknut provides both mechanical fastening and NEC-compliant equipment grounding. Save US$3-5 per connection across thousands of connections. |
| Thin-gauge stamped locknuts from commodity suppliers deform under tightening torque, compromising clamping force and creating potential pullout failures. | Heavy-gauge carbon steel stampings resist deformation at full rated torque. Consistent clamping force across the entire bearing surface. Zero pullout failures in 27 years of field performance. |
| Project submittal packages require UL listing documentation, salt spray test reports, and material certificates — commodity suppliers rarely provide complete technical documentation. | Complete documentation package with every shipment: UL E345464 listing verification, ASTM B117 salt spray test reports, material mill certificates, certificate of origin. Ready for your next project submittal. |
