It features a 1\/4-20 UNC thread size and a 3\/16 inch hex drive, requiring a hex key or Allen driver for installation. The screw measures 2-3\/4 inches in length under the head. Constructed from alloy steel with a black oxide finish coating, it delivers reliable tensile strength with moderate corrosion resistance. This fastener meets ASME\/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies where dimensional consistency and load capacity matter.\u003c\/p\u003e\u003cp\u003eThis socket cap screw is used in a wide range of applications including machinery assembly, equipment mounting, jigs, fixtures, and general mechanical fastening tasks encountered in industrial maintenance and trade work. The partially threaded shank allows for clamping force between mating surfaces without thread engagement through the full grip length. Electricians, pipefitters, millwrights, and general maintenance professionals commonly use this fastener type when securing panel components, brackets, and structural assemblies where a flush or low-profile socket drive head is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4-20 UNC thread size for broad compatibility with standard tapped holes\u003c\/li\u003e\n\u003cli\u003e2-3\/4 inch length under head with partial threading for effective clamping\u003c\/li\u003e\n\u003cli\u003e3\/16 inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced surface reflectivity\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 replacement or stocking fastener for any application requiring a 1\/4-20 UNC partially threaded hex socket cap screw per ASME\/ANSI B18.3 dimensional specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3\/16 inch hex key or Allen-style driver.
