Hex lock nuts use a nylon insert at the top of the nut creating tension between the nut and the threads of the mating component. As the nut is threaded onto a shaft or rod, it will spin freely until the threads from the host part engage the nylon insert.
How do you screw a nylon lock nut?
Slide the socket onto the nylon lock nut and turn the handle of the ratchet clockwise to turn the nylon lock nut onto the fastener. You will feel some resistance from the nylon lock nut as you turn it onto the fastener. This is created by the nylon insert and is completely normal.
What are nylon insert nuts used for?
Nylon lock nuts are used across a wide variety of industries, including in appliances, computers, furniture, medical equipment, vehicles, sheet metal, and aircraft. Heavier nylon insert lock nuts are used in buildings, on bridges, and in railroad equipment.
How do you loosen a nylon lock nut?
Slide sockets over the lock nut until the proper size is found. Turn the nut clockwise, until it begins to loosen from the bolt or screw it is attached to. Fit the socket wrench over the lock nut and turn it counterclockwise to remove it.
Can you reuse a nylon lock nut?
Are Lock Nuts Able to be Reused? They are able to be reused, but only if the prevailing torque meets certain specifications. Lock Nuts with a Nylon Insert are perhaps the most reliable lock nut, as it is only limited by the temperature of the application it has been used in.
What is the difference between a nut and a lock nut?
Traditional nuts simply consist of a basic threaded hole, so constant exposure to vibrations can knock them loose from the bolt on which they are placed. Lock nuts protect against loosening, however, by featuring a design that increases the nut’s resistance to vibrations.
Are nylon nuts one time use?
For example, Carroll Smith (Carroll Smith’s Nuts, Bolts, Fasteners, and Plumbing Handbook) notes that the nylon insert is not damaged by installation and therefore they can be reused many times, and a Federal Aviation Administration Advisory Circular allows nuts to be reused if the prevailing torque is within.
Are lock nuts better than lock washers?
Here is the basic breakdown of when you will want to use a locknut over a lock washer: When you need something that can handle the pressure that comes with torquing down a bolt or screw, choose a lock washer. For those home projects that neither need nor can handle the torque required to tighten it, use a locknut.
Which way does a nylon nut go on?
The top of the nut is where the nylon insert is located. The hex bolt threads from the bottom of the nut through the nylon insert which holds the bolt in place. 1 of 1 found this helpful.
Do you need a washer with a lock nut?
Lock washers are used to keep the nut and bolt in place by preventing them from turning, slipping or coming loose. Place the lock washer between the nut or fastener head, and the corresponding work surface. Ensure that the lock washer’s teeth are completely engaged with the surfaces it’s between. This is imperative.
How does a lock nut work?
Locking nuts work to secure bolted joints by adding friction to the thread of the bolt. Different varieties of locking nut exist, those that utilize metal to create friction, such as the all metal nut, and those that incorporate a polymer in the design, such as the nylon insert nut.
Which way around does a nut go?
The metal thread goes on first. If you’re talking about a nut with a built in fluid seal, due to its design, a Seal Nut will need to go on with the rubber element on the inside.
What are the disadvantages of using lock nuts?
The disadvantage of all types of locknuts is they may try to trick me into thinking they (the locknuts) are sufficient, and proper torque is not THE pre-requisite for a successful dynamically loaded structural joint.
When should you use a lock nut?
Bearing lock nuts, sometimes called shaft locknuts or bearing retaining nuts, are utilized to secure bearings onto a shaft and is designed to prevent the loosening of components due to vibration and rotation.
Are hex nuts and lock nuts the same?
Nylon insert lock nuts are very similar to basic finished hex nuts, but feature a nylon insert lock to help secure the nut into place. When a nylon insert lock nut is installed onto a bolt or screw, the nylon insert wraps around the threads, protecting the connection from loosening due to vibration.
Can you use Loctite with lock nuts?
Here’s what you do. Make sure nuts and bolts are clean and free from oil or dirt. Apply a few drops of Loctite threadlocker on the bolt, where the nut engagement area will be. No need to apply the threadlocker all the way around the bolt.
What is a Stover nut?
Stayloc nuts, or often referred to as Stover nuts, are self-locking. They are prevailing torque, type of hexagon lock nuts. Stover nuts are easy to install as they’re simply screwed on to a thread. Not only that, but they are also available with Flange for secure fastening and are very cost effective.
