Nyloc Nuts

(Self-Locking Nuts with Nylon Insert for Vibration-Resistant Fastening)

At Neo Fasteners, we provide high-quality Nyloc Nuts, also known as Nylon Insert Lock Nuts, specially engineered to resist loosening from vibration and movement. These nuts feature a nylon collar insert at the top that grips the bolt threads securely, making them ideal for high-vibration applications in automotive, machinery, aerospace, construction, and electrical systems.

Whether you're assembling equipment or constructing load-bearing structures, our Nyloc Nuts provide long-lasting locking performance without the need for external locking devices like washers or adhesives.

🔩 Product Overview:

Nyloc Nuts are hexagonal nuts with a non-metallic nylon insert that deforms around the bolt threads when tightened. This creates frictional resistance that prevents the nut from loosening, even under constant motion or vibration. Unlike standard nuts, they are reusable a few times without losing locking power, and they’re compatible with both coarse and fine threads.

Neo Fasteners offers Nyloc Nuts in various grades, materials, and coatings to suit light-duty, general, or heavy-duty industrial use.
