Product Details

Dorman's 784-758D hex lock nuts feature a nylon insert ring that provides secure, vibration-resistant fastening for automotive, industrial, and general maintenance applications. These Grade 2 steel lock nuts are designed to prevent loosening under stress and vibration, making them ideal for critical fastening applications.

Key Features:

  • Thread size: 3/8-16 standard coarse thread
  • Height: 29/64 inches
  • Grade 2 steel construction for reliable strength
  • Nylon insert ring creates friction to resist loosening from vibration
  • Reusable design allows for multiple installations
  • Hex design for standard wrench or socket installation

The nylon locking element deforms around the mating threads to create a prevailing torque that maintains clamping force even in high-vibration environments. These lock nuts meet SAE J995 specifications and are suitable for automotive chassis, suspension, exhaust, and general fastening needs where thread locking is required.

Easy and you had what I needed.

Nice web sit, easy to use and had what I wanted. I'll be back. Part arrived promptly. It was of good quality and exactly what I ordered. I took it to my mechanic and he installed it. It worked and the vehicle passed inspection.

Thanks
