Manufactured from Grade 5 steel with a zinc trivalent chromate finish, it provides corrosion resistance in standard industrial and mechanical applications. The nut features a 1-8 inch thread size, right-hand thread direction, and measures 1-3\/64 inches in height with a 1-7\/16 inch width across flats. The nylon insert creates interference with mating threads, maintaining clamp load without the need for additional locking hardware. This fastener is installed by mechanics, millwrights, electricians, and HVAC technicians in equipment assembly and structural fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis hex lock nut is suited for general-purpose fastening applications in residential, commercial, and light industrial settings. It is commonly used in equipment mounting, mechanical assemblies, and structural connections where thread-locking performance is required without adhesives or split washers. The 1-8 thread size makes it compatible with standard coarse-thread fastener assemblies. Installers working on HVAC equipment frames, electrical enclosures, plumbing supports, and mechanical equipment supports will find this nut appropriate for typical field and shop applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNylon insert locking style resists loosening from vibration without secondary hardware\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction provides adequate tensile strength for general mechanical use\u003c\/li\u003e\n  \u003cli\u003eZinc trivalent chromate finish offers corrosion resistance and meets current RoHS-compatible finishing standards\u003c\/li\u003e\n  \u003cli\u003e1-8 coarse thread size fits standard inch-series fastener assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction for standard installation with conventional tools\u003c\/li\u003e\n  \u003cli\u003eHex profile accepts standard wrenches and sockets for field installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series nylon insert hex lock nut for use with 1-8 coarse-thread bolts and studs in general mechanical and structural fastening assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a standard hex wrench or socket sized for a 1-7\/16 inch width across flats. Nylon insert lock nuts are single-use by industry convention — the nylon insert loses locking effectiveness after removal and should not be reused in critical applications.
