Featuring a 1\/4-28 UNF thread size and fully threaded along its 3\/8-inch length under the head, this screw is driven with a 3\/16-inch hex key. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance. Manufactured to ASME\/ANSI B18.3 and ASTM A574 standards, this fastener is suited for precision assemblies where thread engagement and dimensional accuracy matter.\u003c\/p\u003e\u003cp\u003eThis screw is commonly used in mechanical, HVAC, electrical, and industrial applications where internal hex drive fasteners are specified. The 1\/4-28 UNF fine thread provides greater thread engagement per inch compared to coarse thread, making it well suited for thin materials, high-vibration environments, or assemblies requiring precise torque control. Installers and maintenance technicians working on equipment panels, brackets, and component mounting will find this fastener appropriate for a range of general and light-industrial uses.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-28 UNF fine thread for precise thread engagement and vibration resistance\u003c\/li\u003e\n\u003cli\u003eFully threaded along 3\/8-inch length under head for maximum grip\u003c\/li\u003e\n\u003cli\u003e3\/16-inch hex drive for use with standard Allen or hex key tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduced light glare\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for use in any application specifying a 1\/4-28 UNF fully threaded socket head cap screw.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16-inch hex key or Allen driver.
