SPECIFICATIONS
Heat treated Hex nut with a nylon-filled collar at its back end. The grade-5 nut shall be marked with a dot and dash on the chamfered surface of the nut, 120° apart. When the cap-screw or bolt reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the cap-screw or bolt when it is subjected to vibration. The nylon insert comes in various colors. Designed to be used in structural applications with Grade-5 cap-screws or bolts which have a minimum tensile strength of 120,000 psi.. Nylon insert nuts are not designed to be used at temperatures over 250° F.
