The VALUE COLLECTION 36658 is a heavy hex nut threaded to 3/4-10 UNC specifications with a right-hand thread direction and a 2B class of fit. Manufactured from steel with an uncoated finish, this nut measures 1-1/4 inches across the flats and stands 47/64 inches high. The heavy hex pattern provides greater bearing surface and wall thickness compared to a standard hex nut, making it suitable for structural fastening applications and high-load assemblies. Licensed tradespeople and maintenance professionals working with structural steel, heavy equipment, or process piping commonly use this fastener type.
This heavy hex nut is suited for use in industrial, commercial, and infrastructure fastening applications where a 3/4-10 UNC thread engagement is required. The 2B thread fit class indicates a standard internal thread tolerance appropriate for general-purpose mechanical assemblies. Typical applications include structural steel connections, heavy equipment mounting, and machinery maintenance where enhanced load-bearing capacity is needed over a standard hex nut profile.
Designed as a replacement or supplemental fastener for assemblies requiring a 3/4-10 UNC heavy hex nut with a 2B internal thread fit class.
Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with proper fastener torque practices. Always verify thread engagement and condition of the mating bolt before installation. Follow applicable industry standards such as ASME or AISC specifications for structural fastener torque requirements. Never install a heavy hex nut on a damaged or mismatched thread form.
