The VALUE COLLECTION HNFI8056-050BX is a Grade 8 steel hex nut with a 9/16-18 UNF thread size and a bright uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding mechanical and structural fastening applications. The right-hand thread pattern follows standard UNF specifications, and the nut measures 7/8 inches across the flats with a height of 31/64 inches. This package contains a minimum order quantity of 50 pieces. These nuts are suited for professional tradespeople, contractors, and maintenance technicians working in HVAC, plumbing, electrical, or general mechanical assembly environments.
This hex nut is intended for use in high-strength bolted connections where Grade 8 fastener ratings are required. Typical applications include equipment mounting, structural assemblies, mechanical system repairs, and industrial maintenance. The UNF 9/16-18 thread specification is common across a broad range of OEM mechanical and HVAC equipment hardware. Sold in a box of 50, this nut is appropriate for shop stock, service truck inventory, or job-site use where Grade 8 hardware must be on hand.
Designed for use with 9/16-18 UNF-threaded bolts and studs requiring a Grade 8 hex nut. Suitable as a replacement or stock fastener in any application calling for a UNF 9/16-18 Grade 8 hex nut.
Installation should be performed by a qualified mechanic or tradesperson familiar with proper fastener torque procedures for Grade 8 hardware. Always ensure the mating bolt or stud matches the 9/16-18 UNF thread specification and is also rated Grade 8 or higher when full joint strength is required. Inspect threads on both the nut and bolt for damage or contamination before assembly. Follow applicable equipment manufacturer torque specifications and relevant mechanical codes when tightening fasteners in structural or pressure-bearing assemblies.
