About 5/16"-18 Nylon Insert Hex Lock
Bridge Fasteners has been a leading supplier of Fasteners, nuts, bolts, stainless hardware and contractor products for over 30 years. Quality you can trust! A nylon nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut. It is a nut with a nylon collar insert that resists turning. The plastic insert is placed at the end of the nut, and its inner diameter (ID) is slightly smaller than the major diameter of the screw. The insert deforms elastically over the threads of the screw, but threads are not cut into the nylon. The nylon insert locks the nut by friction against the screw under the applied radial compressive force. Nylon nuts retain their locking ability up to 250 °F (121 °C).
