Nylon Lock Nut (UNC) is a coarse thread self-locking nut designed to provide secure fastening and improved resistance against loosening caused by vibration, movement, or dynamic load. It features a nylon insert inside the nut that grips the matching bolt or threaded stud, creating additional friction to help keep the nut in position after tightening.

UNC stands for Unified National Coarse Thread, which is commonly used in American standard fastening systems. Compared to UNF fine thread, UNC coarse thread has a larger pitch and fewer threads per inch, making it suitable for general fastening, easier installation, repair work, and maintenance applications.

Nylon Lock Nut (UNC) is commonly used in machinery, automotive, construction, agricultural equipment, metal fabrication, maintenance, repair, and general engineering applications where secure locking and coarse thread compatibility are required. It must be used with matching UNC bolts, studs, or threaded rods of the same diameter and thread pitch.

Why Choose Our Nylon Lock Nut (UNC)

Choosing the correct lock nut thread type, material, and finishing is important for thread compatibility, vibration resistance, corrosion protection, and long-term fastening performance. Nylon Lock Nut (UNC) is suitable for users who need a coarse thread locking nut for American standard UNC bolts, studs, and threaded rods.

Steel Nylon Lock Nut (UNC) with Zinc Plated finishing is a practical and cost-effective choice for machinery, automotive, agricultural equipment, fabrication, repair, and maintenance applications. Stainless Steel 304 (A2) is suitable for applications requiring better corrosion resistance, while Stainless Steel 316 (A4) is recommended for outdoor, coastal, marine, chemical-related, or corrosion-prone environments.

The nylon insert helps improve locking performance by adding resistance against loosening, making it suitable for assemblies exposed to vibration, movement, or repeated operation.
