Value Collection MSC-02216141 Heavy Hex Nut 3/8-16 Unc

Product Description

The VALUE COLLECTION MSC-02216141 is a heavy hex nut threaded to 3/8-16 UNC specification with a right-hand thread direction. Manufactured from steel with a galvanized finish for corrosion resistance, this nut measures 11/16 inches across flats and 23/64 inches in height. The heavy hex profile provides a larger bearing surface and greater wall thickness compared to standard hex nuts, making it suitable for high-load structural and mechanical fastening applications. It is commonly installed by pipefitters, millwrights, structural ironworkers, electricians, and general maintenance tradespeople working with bolted connections that require added clamping strength.

This heavy hex nut is used in structural steel assemblies, piping systems, mechanical equipment mounting, and industrial maintenance applications where a standard hex nut does not provide sufficient bearing surface or torque capacity. The galvanized finish makes it appropriate for outdoor, wet, or mildly corrosive environments. This SKU is sold individually but requires a minimum order quantity of 100 units, making it suited for contractors and supply houses stocking fasteners in bulk.

Key Features

• 3/8-16 UNC right-hand thread for compatibility with standard unified coarse thread fastener systems
• Heavy hex profile with 11/16 inches across flats and 23/64 inches height for increased bearing surface
• Steel construction provides strength for structural and mechanical fastening applications
• Galvanized finish offers corrosion resistance in outdoor and mildly wet environments
• Minimum order quantity of 100 units for bulk trade and contractor use

Compatibility

Designed as an OEM-style replacement and general-use heavy hex nut for any 3/8-16 UNC threaded bolt or stud requiring a heavy hex fastener in steel construction.

Installation Notes

Heavy hex nuts are installed by hand-threading onto the mating bolt or stud before torquing with an appropriate open-end, box, or socket wrench. Always confirm thread engagement is complete before applying final torque. Follow applicable code requirements such as AISC or ASME standards for structural and pressure applications. Do not mix thread standards or use damaged threads, as cross-threading will compromise fastener integrity.
