Oct 24, 2023 · What is a lock nut versus an ordinary nut? How do the different types of lock nuts compare? Our guide takes you through the ins and outs of this critical fastener.

A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, [1] stiff nut [1] or elastic stop nut, [2] is a nut that resists loosening under vibrations and torque. Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. [ 2 ]

Locknuts are internally threaded fastener that possesses locking capabilities either by themselves or in concert with another component. By design, lock nuts are engineered to resist loosening when subjected to vibration or torque.

Jan 16, 2025 · Jam nuts are thin nuts used alongside a standard nut to lock it in place, ideal for tight spaces or additional security. They are tightened against the primary nut to secure it, preventing loosening. Jam nuts are useful in applications where space constraints prevent the use of larger lock nuts or where additional locking security is needed.

Lock nuts, also known as locking nuts or self-locking nuts, are a special type of mechanical fasteners designed to resist vibrations, shocks, and other forces that can cause traditional nuts to loosen over time.

Jan 16, 2020 · What is a lock nut and how does it work? Written by Dr. Jody Muelaner. A lock nut is a nut that resists loosening under vibration and torque. There are many types of lock nut but they can be broadly divided into those that use friction to prevent loosening and those that offer some form of positive locking device.

Dec 2, 2024 · Lock nuts are essential components in various mechanical applications that help maintain the integrity of threaded connections. Their primary function is to prevent fasteners from loosening due to vibrations, dynamic loads, or environmental factors, making them vital for safety and performance in numerous industries.

Jan 15, 2025 · A lock nut, also known as a locking nut, prevailing torque nut, or stiff nut, is a specialised type of nut designed to resist loosening under vibration or dynamic loads. Unlike standard nuts, which can gradually loosen over time, lock nuts incorporate various mechanisms to maintain a secure grip on a bolt or threaded standoff .

The locknut is also known as a self-locking nut which prevents the loosening action of the nut under high torque and vibration. During the process, some portion of the lock nuts get elastically deforms and gives locking action. Why use Locknut? Fastening of any equipment takes place with the help of a nut, bolt, and washer.

Apr 30, 2019 · What Is a Lock Nut? Also known as a stiff nut, a lock nut is a special type of nut that doesn’t loosen when exposed to vibrations. In the past, companies would simply use two nuts in applications where vibrations are problematic. After inserting one nut onto the end of the bolt, they would place a second nut on the bolt.
