Metric Nylon Insert Hex Lock Nuts - DIN 985 Black Oxide Steel Class 8

Metric Nylon Insert Lock Nuts Class 8 Steel with Black Oxide Coating Our Metric Nylon Insert Lock Nuts are made from durable Class 8 steel with a protective black oxide coating for enhanced corrosion resistance. The built-in nylon ring, also known as a nyloc collar, creates a compressive force when tightened onto the threads of a fastener, providing superior resistance to loosening and vibration. These lock nuts are ideal for applications where security and vibration resistance are crucial, such as automotive, industrial, and heavy machinery. Key Features Durable Class 8 Steel: Provides excellent strength and reliability. Black Oxide Coating: Adds an extra layer of corrosion protection, especially in indoor environments. Nylon Insert: Resists loosening and vibration, ensuring a secure hold even in high-vibration applications. Reusable: Can be reused if the nylon insert is not compromised and locking torque is within specification. Thread Size: Coarse (standard) threading for ver
