Our All-Metal Nylon Insert Serrated Flange Lock Nuts offer superior fastening reliability for industrial applications requiring enhanced vibration resistance and torque retention. These lock nuts incorporate a nylon insert that provides prevailing torque by generating friction and resistance against the mating threads, preventing loosening under vibrations and dynamic forces. The serrated flange design further improves the locking mechanism by biting into the surface to prevent rotation and distribute load evenly across the bolt or stud, reducing damage to the joint area. Ideal for machinery, automotive, heavy equipment, and structural assemblies, these lock nuts maintain clamp load and joint integrity in challenging environments. The combination of an all-metal body with a nylon locking insert ensures durability, corrosion resistance, and secure fastening performance, minimizing maintenance and increasing safety. The nuts are easy to install with a defined torque threshold providing clear indication of achieving lock engagement, enhancing quality control in assembly lines. Available in various sizes and thread pitches, these lock nuts comply with industrial standards suitable for high-vibration and high-stress applications, establishing them as a premium choice for engineering professionals seeking reliable self-locking fasteners.

The serrated flange bites into the mating surface providing additional resistance to rotation and distributes clamping force evenly, enhancing the overall locking performance and preventing loosening even under severe vibrations.
The nylon insert typically withstands temperatures from -40°C up to 120°C, maintaining its elasticity and friction properties within this range for effective locking.
These nylon insert lock nuts can be reused a limited number of times; however, the locking effectiveness may decrease as the nylon insert wears down after repeated installations.
Our lock nuts are manufactured in compliance with relevant industrial standards such as ISO and DIN specifications for prevailing torque lock nuts to ensure consistent quality and reliability.
Yes, the all-metal body with nylon insert and corrosion-resistant coatings make these lock nuts suitable for automotive environments including exposure to oils and mild chemicals, ensuring long-term secure fastening.

These lock nuts are designed to differentiate between a free-spinning nut and a locknut based on the torque required for installation before clamp loading. The torque needed, such as on a nylon-insert nut, surpasses the resistance caused by the nylon dragging across the mating thread. Typically, this torque is not excessively high compared to the final installation torque.
Our lock nuts, also known as lock nuts, locking nuts, self-locking nuts, prevailing torque nuts, stiff nuts, or elastic stop nuts, serve as essential components that resist loosening in the presence of torque and vibrations. Featuring a unique design, these nuts ensure secure fastening by flexing elastically to produce a locking action. Additionally, some variants spin freely, eliminating the need for additional torque until fully seated.
