1/3Lock Nut / Nyloc Nut
Engineered to prevent dynamic loosening caused by severe shock and vibration, our Yellow Zinc-Plated Nylon Insert Lock Nuts feature an integrated blue nylon collar at the top. As a bolt threads through the nut, the unthreaded nylon ring deforms elastically over the threads, creating a high-friction prevailing torque lock. Combined with a corrosion-resistant yellow zinc dichromate finish, this self-locking fastener provides reliable, long-lasting joint security without damaging bolt threads.

Product description
Yellow Zinc-Plated Hexagon Nylon Insert Lock Nut (Anti-Vibration Nyloc Nut)
- Self-Locking Nylon Collar: Features an integrated blue nylon insert at the crown that grips bolt threads securely, preventing accidental backing-out and loosening under intense dynamic vibration or thermal cycling.
- Non-Damaging Prevailing Torque: The resilient nylon material conforms to the mating bolt threads to generate consistent prevailing torque without galling, stripping, or wearing out the metal threads.
- Yellow Zinc Dichromate Finish: Electroplated with a bright yellow zinc coating, offering exceptional protection against oxidation, rust, moisture, and chemical exposure in harsh industrial environments.
- Standard Hexagon Geometry: Precision-machined 6-sided hex profile ensures uniform dimensioning and easy installation using standard sockets, wrenches, or automated assembly tools.
- Durable Carbon Steel Body: Forged from high-grade carbon or alloy steel to ensure superior tensile strength, structural rigidity, and dependable load distribution.
- Versatile Applications: Widely used in automotive assemblies, agricultural equipment, machinery joints, lawn and garden power tools, conveyor systems, and industrial structures subjected to continuous vibration.
