The VALUE COLLECTION MP39603 is a 3/8-16 UNC right hand hex nut manufactured from steel with a zinc yellow dichromate finish. It measures 9/16 inches across the flats and 21/64 inches in height. This standard hex nut is used to fasten threaded fasteners in a wide range of mechanical, structural, and equipment assembly applications. The zinc yellow dichromate coating provides corrosion resistance over the base steel material. Installation requires a standard hex wrench or socket. This type of fastener is commonly installed by maintenance technicians, pipefitters, electricians, and general mechanical trades across residential and commercial settings.
This hex nut is suited for use in general-purpose threaded assemblies where a 3/8-16 UNC right hand thread engagement is required. Typical applications include equipment mounting, pipe hanger hardware, panel assembly, and structural connections. The UNC thread standard is the most widely used coarse thread series in inch-based fastener systems, making this nut broadly compatible across a range of standard bolts, studs, and threaded rod in 3/8-16 UNC configuration.
Designed as a standard replacement or stock hex nut for use with 3/8-16 UNC right hand threaded bolts, studs, and threaded rod in general mechanical and structural assemblies.
This hex nut is installed by hand-threading onto a compatible 3/8-16 UNC right hand threaded fastener, then torqued to the fastener manufacturer or application specification using a standard hex wrench or socket. Always ensure mating threads are clean and free of debris before installation. Do not cross-thread or overtorque. Follow applicable mechanical or structural codes for the installation environment.
