🔩 Nyloc Nut (Nylon Insert Lock Nut) – Secure Self-Locking Nut | Neo Fasteners
Nyloc Nuts, also called Nylon Insert Lock Nuts, are hexagonal nuts featuring a nylon collar insert that increases friction on the bolt thread, preventing the nut from loosening due to vibration, torque, or motion. They are widely used in automotive, aerospace, machinery, electronics, and structural assemblies where a secure, vibration-resistant fastening is critical.
At Neo Fasteners, we offer a wide range of Nyloc Nuts in metric and inch sizes, manufactured from high-quality materials including Stainless Steel, High Tensile Steel, Brass, and Mild Steel, with multiple finishes and certifications.
✅ Key Features
- Self-locking action due to embedded nylon ring
- Resists loosening under vibration and dynamic loads
- Reusable a limited number of times without loss of grip
- Suitable for high-speed and safety-critical assemblies
- Operates in temperatures typically up to 120°C (special versions available for high-temp)
