The VALUE COLLECTION R56001386 is a 3/8-24 UNF hex nut machined from Grade 316 stainless steel with a bright, uncoated finish. It features a right-hand thread and measures 9/16 inches across the flats with a height of 7/32 inches. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it well suited for wet, marine, and chemically aggressive environments. This nut is installed by mechanical, plumbing, and maintenance trades wherever a standard hex fastener is required and corrosion resistance is a priority.
This hex nut is appropriate for use in residential and commercial applications where exposure to moisture, salt air, or mild chemicals is expected. Typical installations include marine hardware, pool and spa equipment, HVAC structural assemblies, plumbing brackets, and outdoor mechanical enclosures. It mates with any 3/8-24 UNF-threaded fastener and is suitable for both new construction and repair work where corrosion-resistant hardware is specified.
Designed as a standard 3/8-24 UNF hex nut for use with any male-threaded fastener conforming to the UNF 3/8-24 thread standard.
Installation requires a standard 9/16-inch open-end wrench or socket. Always ensure the mating bolt or stud is clean and free of debris before threading to avoid galling, which is a known risk with stainless fasteners. Apply an anti-seize compound to the threads when joining stainless-to-stainless hardware to reduce galling risk. Follow applicable mechanical codes and torque guidelines for the specific joint design.
