A4 nylon insert nut
Stainless steel nylon insert nut, which is known as A2 grade, is actually produced from 316 grade steel. Nylon insert nut actually uses a polymer washer made of polypropylene or plastic in the upper part. This washer is installed on the upper edge of the steel felt bowl nut and is cut by the sharp threads of the screw when connecting the screw. The cutting of the washer by the screw causes the nut of the nylon insert nut to be connected on the surface of the attached screw with a higher tension. Therefore, the steel nylon insert nut is used in cases where the vibration in the system is high and the connection of simple screws can be opened.
