The Nylon Lock Nut (also known as a Nyloc nut or Nylon Insert Lock Nut) is a specialized fastener designed to prevent loosening under intense vibration and torque. Unlike standard Hex Nuts, these components feature a captive non-metallic insert that creates a friction-based locking mechanism by tightly gripping the bolt threads. At Tianqi Fasteners, we manufacture these essential hardware components to rigorous international standards, including DIN 982, DIN 985, and ANSI/ASME B18.16.6, ensuring a secure and maintenance-free connection for critical assemblies.
Our extensive selection of Stainless Steel Nylon Lock Nuts is crafted from high-grade 304, 316, and 316L materials to provide superior durability in corrosive environments. Whether you require the specialized load distribution of a Flange Nylon Lock Nut for automotive use or a “thick” DIN 982 variant for heavy industrial machinery, our products offer the reliable mechanical integrity needed for demanding marine, construction, and manufacturing applications.
The non-metallic nylon insert provides consistent friction that prevents the nut from backing off, even when subjected to constant dynamic loads.
Available in 304 and 316 stainless steel grades, our nuts are engineered to resist rust and chemical exposure in humid or marine settings.
Our Flange Nylon Lock Nut variants feature a built-in flange that acts as a washer, spreading clamping force evenly to protect the mating surface.
We offer “thick” nylon locking nuts that provide increased thread engagement and higher load-bearing capacity for heavy-duty structural projects.
All Nylon Insert Lock Nuts strictly adhere to DIN and ANSI/ASME specifications, ensuring dimensional accuracy and international compatibility.
High-quality construction ensures resistance to wear and deformation, providing a long-lasting fastening solution for industrial and commercial use.
