EUCLID E4961A Part Description

Manufacturer

EUCLID

Features & Benefits

  • Maintains thread tension without backing off under repeated motion
  • Often used in suspension mounts, axle hubs, and load-bearing assemblies
  • Supports long service intervals with minimal re-tightening required
  • Helps prevent mechanical failures related to joint separation
  • Compatible with standard thread systems in heavy-duty vehicles

Euclid Lock Nut

Fasteners play a critical role in structural integrity, especially in high-vibration areas. The Euclid Lock Nut secures threaded components in place by maintaining consistent tension even as the vehicle moves. Often used on suspension and wheel-end assemblies, the Euclid E4961A helps reduce the risk of unwanted loosening due to road conditions or system fatigue.
