Checknuts, or locknuts, are used to prevent nuts from coming loose due to movement and vibration. They have a nylon insert that grips the threads when installed correctly. To install, slide the nut onto the bolt or stud shaft and rotate clockwise until resistance is felt, then use a wrench to tighten.
A check nut is used to ensure that a nut, once installed, will stay in place. Checknuts, also called locknuts, are usually thin and used in cases where there is a high likelihood that the first nut will rattle or vibrate loose. These nuts are designed and used to prevent the first nut from coming loose and causing damage or injury while using a device. Locknuts, or jam nuts, were designed to replace lock washers, which didn’t work as well at preventing loosening over time from movement and vibration.
The modern locknut is typically made to look like the regular castle nut. There is, however, a nylon insert on the inside of the locknut. The nylon insert is the key component of the nut.
When installed correctly, the nylon insert on the check nut grips the threads. This allows the nut to take a firmer hold on the bolt or stud it is being applied to. This feature ensures that the nut remains securely in place and will not loosen due to movement and vibration.
The control nuts will only work as they should when installed correctly. To properly install a check nut, you must have the stud or bolt to which the nut is applied and the correct size wrench or two. Next, the user must pick up the dice.
To install, the user slides the check nut onto the bolt or stud shaft and rotates it clockwise until the nylon insert inside the nut catches the first thread. It will be clear when it has done this because the user will feel some resistance and will no longer be able to turn it by hand.
Once the user feels this resistance, they should grab the correct size wrench and turn the nut all the way down the stud or bolt shaft with the wrench. This will ensure a snug fit. It needs to be rotated until the lock nut is right against the other nut. If needed, the second key can be used to hold the other end of the stud or bolt shaft. A tight fit against the shaft and against the first nut will ensure that the locknut performs its key function of keeping the other nut from loosening over time from movement and vibration.
