Dorman Hex Lock Nut with Nylon Insert Class Height

Dorman hex lock nuts with nylon insert, also called nylon lock nuts, nyloc nuts or prevailing torque lock nuts, are metric Class 8 fasteners. They are made for body hardware and general-purpose use. The nylon ring in each nut grips the bolt threads. This helps the nut resist loosening from vibration, so it stays secure in the places where a standard hex nut might work loose.

Key Features:

• Nylon insert design: The nylon ring creates locking friction on the bolt threads and helps keep the fastener in place under vibration.
• Class 8 strength: Metric Class 8 construction suits many automotive and general hardware applications.
• Hex style: The standard hex head works with common wrenches and sockets.
• Durable materials: Manufactured with durable materials and corrosion tested for strength and longevity.
• Replacement hardware: Restores hardware that has been lost or has failed from fatigue.
• Multipurpose use: Works in many automotive, home and shop applications.
