Product details

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.

Frequently asked by buyers
How does the serrated flange improve the locking performance of these nylon insert lock nuts?

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.

What temperature range can the nylon insert withstand without losing its locking properties?

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.

Are these lock nuts reusable after initial installation?

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.

What standards do these lock nuts comply with to ensure industrial reliability?

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.

Can these lock nuts be used in automotive applications exposed to oil and chemicals?

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.
