  • Nylon insert locking provides positive, vibration-resistant locking action that reduces loosening under load.
  • Grade C medium carbon steel offers dependable strength and durability for demanding applications.
  • Phosphate coating with oil enhances corrosion resistance and lubricity for easier installation and longer service life.
  • Thread size 7/8-9 UNC is compatible with standard bolts and nuts using 7/8 inch diameter with 9 threads per inch.
