Sized at 1\/4-28 UNF with a 3\/8-inch length under head, this fastener is fully threaded and driven with a 3\/16-inch hex key. The alloy steel construction is finished with a black oxide coating, which provides mild corrosion resistance and reduces light reflection. This screw meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional accuracy and tensile performance are required.\u003c\/p\u003e\n\u003cp\u003eThis socket cap screw is commonly used in close-clearance installations where a standard hex bolt head would not fit. Typical applications include machine frames, fixtures, tooling plates, equipment panels, and mechanical assemblies across industrial, HVAC, electrical, and plumbing trade environments. The fine 1\/4-28 UNF thread pitch provides stronger thread engagement in thinner materials compared to coarse-thread equivalents, and the socket drive allows installation with a standard hex wrench or Allen key in confined spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-28 UNF fine thread for high thread engagement in thin or tapped metal sections\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch length under head, fully threaded along entire shank\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch hex socket drive for use with standard Allen wrenches or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 tensile requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 socket cap screw suitable for any tapped or clearance hole application requiring a 1\/4-28 UNF fine-thread fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 3\/16-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before driving. Apply thread locker or anti-seize compounds as required by the application.
