Value Collection MSC-85839785 Hex Nut 5/8-11 A194 Grade 2H

Product Description

The VALUE COLLECTION MSC-85839785 is a heavy hex nut manufactured to ASTM A194 Grade 2H specifications, designed for high-strength bolted assemblies in structural, industrial, and mechanical applications. It features a 5/8-11 UNC thread size with right-hand thread direction and a hot-dip galvanized finish for corrosion resistance. The nut measures 1-1/16 inches across the flats and 39/64 inches in height. At 0.12 pounds per unit, it is suited for use with corresponding 5/8-inch diameter fasteners in flanged connections, pipe supports, and general structural bolting where A194 Grade 2H compliance is required.

This hex nut is commonly used in commercial and industrial construction, structural steel erection, pressure vessel assembly, and pipe flange bolting. It is appropriate for applications requiring a heavy-duty steel nut with documented material grade traceability. The galvanized finish provides baseline protection against oxidation in outdoor and moderately corrosive environments. Plumbers, pipefitters, ironworkers, and mechanical contractors typically specify A194 Grade 2H nuts when pairing with A193 grade stud bolts on flanged piping and equipment connections.

Key Features

• A194 Grade 2H steel construction for verified high-strength performance in structural and pressure applications
• 5/8-11 UNC right-hand thread for standard compatibility with 5/8-inch bolts and threaded rod
• Galvanized finish provides corrosion resistance for outdoor and industrial environments
• 1-1/16 inches across flats — accepts standard 1-1/16-inch hex wrenches and sockets
• 39/64-inch height consistent with heavy hex nut profile for increased bearing area

Compatibility

Designed as an OEM-style replacement or new-installation hex nut for use with 5/8-11 UNC threaded fasteners in structural, piping, and mechanical bolting assemblies requiring A194 Grade 2H compliance.

Installation Notes

Installation is typically performed by ironworkers, pipefitters, or mechanical contractors using a 1-1/16-inch wrench or impact socket. Torque values should be determined by the project engineer or applicable code reference such as AISC or ASME B16.5 for flanged connections. Ensure mating bolt threads are clean and free of debris before assembly. Do not use with mismatched thread standards or grades without engineering review.
