Manufactured from Grade 2 steel with a cadmium finish for corrosion protection, this nut features right-hand threading and a flanged seat measuring 0.9280 inches in flange diameter. The hex body measures 15\/16 inches (0.9375 inches) across the flats and 1.0590 inches across the points, with a height of 0.7590 inches. It meets MIL-S-7742 military specifications, making it appropriate for defense, industrial, and demanding mechanical assembly applications. Installed by maintenance technicians, millwrights, and general contractors in metal fabrication and structural fastening work.\u003c\/p\u003e\u003cp\u003eThis hex lock nut is suited for use in residential, commercial, and military-grade mechanical assemblies requiring a reliable threaded connection at the 5\/8-11 thread size. The expanding flex top design provides consistent locking force without the need for additional locking hardware such as separate lock washers. It is commonly used in structural, equipment mounting, and general mechanical assembly scenarios where vibration or dynamic loading could otherwise allow fastener loosening over time.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExpanding flex top locking style provides vibration-resistant hold without separate lock washers\u003c\/li\u003e\n\u003cli\u003eGrade 2 steel construction with cadmium finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eMeets MIL-S-7742 military specification for demanding applications\u003c\/li\u003e\n\u003cli\u003eRight-hand, 2B thread fit class ensures standard compatibility with 5\/8-11 threaded fasteners\u003c\/li\u003e\n\u003cli\u003eFlanged seat aids load distribution across mating surfaces\u003c\/li\u003e\n\u003cli\u003eSold in packages of 25 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 5\/8-11 UNC right-hand threaded bolts and studs in inch-measurement fastening systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a standard hex wrench or socket sized to 15\/16 inches across the flats.
