Nyloc Nuts are a must have fastener in many projects. Engineering, automotive and much more. Nyloc nuts are also referred to as a nylon-insert lock nut, polymer-insert lock nut or elastic stop nut. The nylon collar found in the nut is designed to resist turning. The plastic insert is placed at the end of the nut, with the inner diameter slightly smaller than the diameter of the screw. This design ensures a tight and secure fit. Thus countering applications where vibration is an issue and reducing the risk of a fastener working loose. Clarik have high quality standards.
