This hex nut is commonly used in residential and commercial construction, mechanical rooms, industrial equipment mounting, and structural steel assemblies where a 1-7/8-12 UN thread pattern is specified. The uncoated bright finish is appropriate for dry or protected environments. It is packaged as a single unit, suitable for low-quantity replacement or repair jobs requiring a specific thread size and grade.
Designed as an OEM-style replacement or standard hex nut for applications requiring a 1-7/8-12 UN thread pattern in Grade 2 steel fastener specifications.
Installation is performed by licensed mechanics, millwrights, pipefitters, or qualified maintenance technicians. Always de-energize and isolate connected equipment before servicing fastened assemblies. Use a properly sized wrench or socket matched to the 2.75-inch across-flats dimension to avoid rounding the hex. Follow applicable torque requirements per the governing structural or mechanical code for the installation type.
