Manufactured from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers high tensile strength and corrosion resistance in demanding mechanical and structural applications. The 3\/8-16 UNC thread size and right-hand thread direction make it compatible with standard fractional fastener systems. At 29\/64 inches high and 9\/16 inches across the flats, it fits standard 9\/16-inch hex tooling. The nylon insert provides a prevailing-torque locking mechanism that does not require secondary locking hardware. Machinists, maintenance mechanics, and assembly technicians commonly install these nuts in equipment, machinery, and structural assemblies.\u003c\/p\u003e\u003cp\u003eThis nut is suited for industrial, automotive, agricultural, and general mechanical assembly applications where vibration resistance is required. The Grade 8 steel construction makes it appropriate for high-load bolted joints in fabrication and OEM assembly environments. It is sold individually but carries a minimum order quantity of 100 pieces, making it practical for production runs, maintenance stock, and MRO inventory replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNylon insert locking mechanism resists loosening from vibration without secondary hardware\u003c\/li\u003e\n\u003cli\u003eGrade 8 steel construction for high-strength bolted joint applications\u003c\/li\u003e\n\u003cli\u003eZinc yellow dichromate finish provides corrosion resistance\u003c\/li\u003e\n\u003cli\u003e3\/8-16 UNC right-hand thread for compatibility with standard fractional fastener systems\u003c\/li\u003e\n\u003cli\u003e9\/16-inch width across flats fits common hex tooling\u003c\/li\u003e\n\u003cli\u003eMinimum order quantity of 100 pieces supports production and MRO stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/8-16 UNC threaded bolts and studs in standard inch-measurement fastener applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall using a standard 9\/16-inch hex wrench or socket.
