Introduction

DIN 985 Nylon Insert Lock Nuts, commonly known as Nyloc nuts, are essential fasteners for assemblies subject to vibration, dynamic loads, or frequent temperature changes. The core feature is a non-metallic (typically nylon or polymer) insert at the top of the nut. When the nut is tightened onto a bolt, the insert deforms over the bolt threads, creating a prevailing torque that resists loosening. This mechanical resistance ensures a secure joint even when the bolt tension may temporarily decrease.

Applications

  • Automotive Chassis: Used in areas prone to high vibration, such as engine mounting and suspension.

  • Agricultural Machinery: Securing moving parts on tractors and implements exposed to rugged terrain.

  • Vibrating Screens and Conveyors: Essential for maintaining tension in dynamic industrial equipment.

  • Aerospace (Non-critical): Used in assemblies requiring a mechanical lock against rotation.

Advantages

  • Excellent Vibration Resistance: The nylon insert provides reliable locking even when the main thread load is lost.

  • Sealing Function: The nylon material can offer a slight seal against moisture and oil ingress along the threads.

  • Reusable: Can be reused several times (though locking performance degrades slightly with each cycle).

  • Non-Damaging: Does not damage the mating thread of the bolt upon installation.

Payment & Shipping

We offer customized Kanban systems and volume discounts for continuous supply contracts, accepting TT 30 Days. Due to the nylon component, Nyloc nuts are packaged in moisture-resistant containers and stored in climate-controlled areas prior to shipment to preserve the integrity of the polymer insert.

FAQ

  • Q: Are Nyloc nuts suitable for high-temperature applications?
  • A: No. The nylon insert has a relatively low melting point. They should not be used in applications where the temperature exceeds the specified limit (typically 121∘C). For high-temperature locking, all-metal prevailing torque nuts or castle nuts are better alternatives.
  • Q: How many times can a Nyloc nut be reused?
  • A: While they can be reused, it is generally recommended to limit reuse to 3-5 times, especially in critical applications. After each installation/removal cycle, the nylon deforms further, and the locking torque will gradually decrease.
