Sized at 1\/4-28 UNF with a 3\/4-inch length under head, this fastener is fully threaded and driven by a 3\/16-inch hex key. Constructed from alloy steel and finished with a zinc-plated coating for corrosion resistance, it meets ASME B18.8 and ASTM A574 standards. It is a standard choice for mechanical assemblies, brackets, and equipment panels where a low-profile socket head and fine-thread pitch are specified.\u003c\/p\u003e\n\u003cp\u003eThis screw is used across a wide range of trade and industrial applications, including HVAC equipment assemblies, electrical enclosures, plumbing fixture mounting, and general mechanical fabrication. The 1\/4-28 UNF fine thread provides tighter thread engagement per inch compared to coarse-thread equivalents, making it well suited for thin-material fastening and applications where vibration resistance or precise torque control is important. It is typically installed by HVAC technicians, electricians, pipefitters, and general maintenance professionals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine-thread profile for tight engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/4-inch length under head for maximum thread contact\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard hex keys or Allen-head drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides baseline corrosion protection in indoor environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.8 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4-28 UNF hex socket cap screw suitable for threaded holes or nuts conforming to ASME B18.8 and ASTM A574 specifications in mechanical, HVAC, electrical, and plumbing assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/16-inch hex key or socket driver; ensure the mating threaded hole is clean and free of debris before driving.
