Product Details

The Dorman 814-043 is a Grade 2 hex lock nut with nylon insert, featuring a 7/16-20 fine thread (SAE) specification. Also commonly referred to as a nylon insert lock nut or nylock nut, the integrated nylon collar creates friction against the mating bolt threads, resisting loosening caused by vibration and torque — no additional locking hardware required.

Key Features:

  • Thread Size: 7/16-20 (SAE fine thread)
  • Grade: Grade 2 steel construction
  • Locking Mechanism: Nylon insert (nylock) for vibration-resistant retention
  • Material: Steel with corrosion-resistant finish
  • Thread Type: Fine thread (20 TPI)
  • FQA Compliant Fastener
  • Manufactured to specific thread tolerance standards for reliable fit
  • Salt spray corrosion tested for long-term durability
  • Multipurpose design suitable for automotive, marine, RV, powersports, and general hardware applications

Backed by Dorman's team of professional engineers and quality control specialists, the 814-043 is a dependable hardware solution for repair technicians and DIY enthusiasts alike. Sold individually unless otherwise noted.
