CHECK NUT

A check nut is used to ensure that a nut, once installed, will stay in place. Check nuts, also called lock nuts, are usually thin and used in instances where there is a high probability of the first nut shaking or vibrating loose. These nuts are designed and used to prevent the first nut from becoming loose and potentially causing damage or injury when using a device. Lock nuts, or check nuts, were designed to replace lock washers, which did not work as well at preventing loosening over time from movement and vibration.Contact us for quality check nuts
