The nylon creates friction against the bolt threads when the nut is tightened. This friction helps to prevent the nut from loosening over time, making it ideal for applications where vibrations are present, such as in automotive, aerospace, and machinery settings.Bespoke fasteners can be manufactured to order in non-standard sizes and specialist material grades – minimum order quantities apply.
