Value Collection B52001667 Hex Nut 1-1/2-12 Unf Grade 5

Product Description

The VALUE COLLECTION B52001667 is a Grade 5 steel hex nut threaded to a 1-1/2-12 UNF right-hand specification. Measuring 2.25 inches across the flats and 1.317 inches in height, this nut is designed for fastening applications that require a unified fine thread in the 1-1/2-inch diameter range. The bright, uncoated finish is typical for general-purpose mechanical assemblies. It is installed by millwrights, industrial mechanics, pipefitters, and other tradespeople working with large-diameter fastener systems in structural, mechanical, or equipment maintenance contexts.

This hex nut is suited for use in industrial and commercial applications where a 1-1/2-12 UNF thread form is required. Fine-thread fasteners in this size range are commonly used in high-vibration environments or wherever precise preload control is needed. Typical applications include heavy equipment assembly, machinery maintenance, and structural fastening tasks requiring Grade 5 material strength. This nut is sold individually per package, with a minimum order quantity of 10 units.
