Non-metallic insert is a layer of non-metallic material (generally nylon 66) inlaid around the inner thread of the nut, which acts as a lock when being tightened. It is generally used in non-removable applications. Locking principle: the inner thread of the nut is covered by a layer of non-metallic material, when screwed into the outer thread, the non-metallic material is destroyed and the gap between the threads is filled, which increases the resistance when rotating back and plays the role of anti-loosening and locking. A nylon insert on these metric nuts prevents vibration from loosening them, and a domed head protects the threads at the end of the bolt from damage and debris. These nuts are reusable, but the nylon insert’s holding power decreases with each use. Also known as acorn nuts, they create a finished appearance and can reduce snagging on wires and insulation. Nuts meet DIN 986, an international standard for domed cap nut dimensions. These nuts are made of strong and wear-resistant Class 6 steel. Zinc plating extends the life of the nut by protecting the inner steel from rust.
