This aerotight self-locking nut from RS PRO is designed to keep bolts securely held in position. Even when high levels of vibration occur, the cantilevered threading on the nut's inner ring holds fast to the bolt and stops it from loosening.
The nut has a self-locking design, keeping it firmly in place even when it's not tightened. This feature significantly reduces the risk of human error when using the nut and it also saves you time when you apply it.
You can remove the nut and reuse it again later, without the quality of its grip deteriorating. You will find this product suitable for use in high temperatures as it's made with type-316 A4 grade stainless steel, which makes it suitable to use in industrial environments.
