Description

Engineered for reliability in demanding assemblies, the Hex Lock Nuts NU Nylon Inserts 18/8 Stainless 1/2-13 delivers secure, vibration-resistant fastening with corrosion resistance you can count on. These hex lock nuts combine a durable 18/8 stainless steel body with a high-strength nylon insert that creates a positive locking action, helping prevent loosening under shock and dynamic loads.

Key Features

  • Nylon insert lock provides positive locking that resists loosening under vibration and temperature fluctuations.

  • 18/8 stainless steel (304-grade) delivers excellent corrosion resistance and a clean, bright finish.
  • Hex lock nut design offers easy wrench access and a secure grip during installation.
  • Thread size 1/2-13 UNC — standard coarse thread for common fastener compatibility.
