It features a right-hand thread and measures 0.75 inches across the flats with a height of 0.4375 inches. This standard fastener is used to secure threaded assemblies in light- to medium-duty applications across mechanical, plumbing, HVAC, and general construction work. Installation requires a standard 3\/4-inch wrench or socket. The zinc coating provides basic corrosion resistance for indoor and moderately exposed environments.\u003c\/p\u003e\n\u003cp\u003eThis hex nut is suited for use in residential and light commercial settings where Grade 2 steel fasteners meet the load and torque requirements of the assembly. It is commonly used by plumbers, HVAC technicians, electricians, and general contractors during equipment installation, mounting, and structural fastening tasks. The 1\/2-20 UNF thread pattern is a fine-thread designation, making it appropriate for applications requiring finer thread engagement than standard UNC fasteners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF right-hand thread for fine-thread fastening applications\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction for light- to medium-duty use\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish for basic corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e0.75 inches across the flats — fits standard 3\/4-inch wrenches and sockets\u003c\/li\u003e\n  \u003cli\u003e0.4375 inches in height — compact profile for tight clearance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any 1\/2-20 UNF threaded bolt or stud requiring a standard Grade 2 hex nut.

Ensure mating bolt or stud thread standard matches UNF before assembly. Do not use in applications requiring Grade 5 or Grade 8 fasteners, as Grade 2 is not rated for high-tensile or safety-critical connections.
