Descrizione del prodotto

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 ChallengeHX 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.
"We specified HX grounding locknuts for a 12-building hospital campus project after experiencing vibration-related connection failures with our previous supplier. Three years post-installation, zero bonding failures across 8,400+ connections. The documentation package satisfied the owner's commissioning agent on the first review." — Senior Electrical Engineer, Commercial Construction Firm

Key Engineering Features
  • Serrated Tooth Grounding Geometry — Cuts through paint, powder coat, and surface oxidation. Establishes direct metal-to-metal contact for NEC 250 compliant bonding.
  • Anti-Vibration Mechanical Lock — Tooth profile interlocks with enclosure surface to resist loosening from machinery vibration, seismic events, and thermal cycling.
  • Heavy-Gauge Carbon Steel Body — Resists deformation under full rated torque. Maintains uniform clamping force across entire bearing surface.
  • Reversible Installation Design — Either face contacts the enclosure. Works in tight spaces where wrench access is limited from one direction.
  • UL E345464 Listed with Full Documentation — Complete submittal package included: listing verification, salt spray reports, material certificates, certificate of origin.
Application Environments
  • Industrial Manufacturing Plants — Heavy machinery vibration zones where conventional locknuts loosen over time
  • Commercial High-Rise Buildings — Electrical rooms and distribution panels requiring documented grounding for life safety systems
  • Wastewater Treatment Facilities — Damp and corrosive atmospheres demanding superior plating protection
  • Transportation Infrastructure — Subway stations, airport terminals with enhanced public safety grounding requirements
  • Seismic Zone Construction — Building codes requiring electrical components to maintain connection integrity during and after seismic events
  • Data Center Power Distribution — UPS systems where fault-current paths must operate reliably under all conditions
Packaging & OEM

Quantity-counted heat-sealed polybags in partitioned export cartons. Palletized with stretch wrap and corner protectors. OEM private-label carton printing, branded polybags, QR-coded labels. Custom kitting: pre-packaged by floor, zone, or electrical room per contractor installation schedule. 12-month manufacturing defect warranty with free replacement for any quality non-conformance.
