Value Collection MSC-67481168 Hex Nut 1-8 Unc Grade 2

Product Description

The VALUE COLLECTION MSC-67481168 is a 1-8 UNC hex nut manufactured from Grade 2 steel with a bright, uncoated finish. This standard hex nut features right-hand threading and measures 1-5/8 inches across flats with a height of 63/64 inches. It carries a 2B thread fit class and conforms to ASME B1.1 and ASME B18.2.2 fastener standards. Hardness ranges from Rockwell B68 to C32, providing the moderate strength typical of Grade 2 fasteners. Licensed tradespeople and general contractors use these nuts in structural assemblies, mechanical installations, and maintenance applications where high-strength alloy fasteners are not required.

This hex nut is suited for general-purpose fastening in residential and light commercial construction, mechanical equipment assembly, and maintenance work. The 1-8 UNC thread size is one of the most common coarse-thread specifications in North American trade work, making this nut a routine stock item for plumbing, HVAC support structures, electrical conduit supports, and similar service applications. The uncoated finish is appropriate for indoor or protected environments where corrosion resistance is not a primary requirement.

Key Features

• 1-8 UNC coarse-thread specification for broad compatibility with standard Grade 2 bolts and threaded rod
• Grade 2 steel construction with Rockwell B68-C32 hardness for general-purpose strength
• 1-5/8 inch across flats for use with standard 1-1/2 inch wrench or socket
• 2B thread fit class per ASME B1.1 ensures consistent thread engagement
• Bright uncoated finish suitable for dry or protected indoor installations
• Conforms to ASME B18.2.2 fastener dimensional standard

Compatibility

Designed as a general-purpose replacement or stock hex nut for use with 1-inch nominal diameter, 8 threads-per-inch UNC-threaded fasteners conforming to ASME B1.1 and ASME B18.2.2 standards.

Installation Notes

Installation is typically performed by general tradespeople, maintenance technicians, or mechanical contractors using a standard wrench or socket sized for 1-5/8 inches across flats. Ensure mating bolt or threaded rod thread specification matches 1-8 UNC before installation. Do not use impact tools at torque levels that exceed the Grade 2 material rating. Inspect threads for damage or contamination before assembly to ensure proper thread engagement.
