The VALUE COLLECTION MP39615 is a 1/2-20 UNF right-hand hex nut manufactured from steel with a zinc yellow dichromate finish. It measures 0.75 inches across the flats and stands 0.4375 inches high. The zinc yellow dichromate coating provides corrosion resistance in general-purpose fastening applications. This nut is a standard hardware component used by plumbers, pipefitters, electricians, HVAC technicians, and mechanical contractors wherever a 1/2-20 UNF threaded connection is required. It is sold individually but carries a minimum order quantity of 25 pieces.
This hex nut is suited for residential and light commercial applications requiring a fine-thread 1/2-20 UNF fastener. It is commonly used in mechanical assemblies, equipment mounting, and structural fastening tasks where right-hand thread engagement and a corrosion-resistant finish are specified. The standard hex profile accepts common wrench and socket drive tools found in any trade toolbox.
Designed as a general-purpose replacement or supplemental hex nut for any application requiring a 1/2-20 UNF right-hand threaded fastener with a standard hex profile.
Installation of hex nuts is performed by licensed tradespeople or qualified mechanics depending on the application. Always de-energize or shut off the relevant system before working on fastened assemblies. Use an appropriately sized wrench or socket to avoid rounding the flats. Follow applicable codes and equipment manufacturer torque guidelines where specified by the equipment documentation.
