The VALUE COLLECTION R63084241 is a 3/8-16 UNC hex nut machined from Grade 316 stainless steel with a bright, uncoated finish. Grade 316 stainless offers strong resistance to corrosion and chloride environments, making it a reliable choice for marine, chemical, food-service, and outdoor applications. The nut measures 9/16 inches across the flats and 21/64 inches in height, conforming to standard UNC thread geometry with a right-hand thread direction. Plumbers, pipefitters, electricians, and general mechanical contractors routinely specify 316 stainless fasteners wherever moisture exposure or harsh chemicals are a concern.
This hex nut is suited for use in residential and commercial installations where corrosion resistance is a primary requirement. Typical applications include pipe flange assemblies, equipment mounting in wet or chemical environments, pool and spa mechanical systems, HVAC condensate and drainage hardware, and marine-grade structural connections. The standard 3/8-16 UNC thread pattern ensures broad compatibility with correspondingly threaded bolts, studs, and threaded rod across a wide range of trade and industrial applications.
Designed for use with 3/8-16 UNC threaded bolts, studs, and threaded rod in applications requiring Grade 316 stainless steel fasteners.
Installation should be performed by a qualified tradesperson following applicable mechanical and structural codes. Always verify thread engagement is sufficient before applying torque, and use a properly sized wrench or socket to avoid rounding flats. When installing in dissimilar metal assemblies, consider galvanic isolation measures appropriate to the application. Inspect mating threads for damage or contamination before assembly.
