Manufactured from alloy steel with a black oxide finish, this fastener delivers reliable clamping force and moderate corrosion resistance in dry or lightly oiled environments. The 9\/16-18 UNF thread form provides a fine-pitch engagement suited to precision load applications. Drive is a 7\/16-inch hex socket, compatible with standard Allen keys and socket drivers. Weighing 0.01 pounds, the screw is sized for controlled torque applications where thread engagement and material strength are primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in machinery frames, tooling fixtures, automotive components, and fabricated steel assemblies where a recessed drive head is required to maintain a flush or low-profile surface. The fine UNF thread series makes it appropriate for applications requiring precise adjustment or where vibration resistance is needed. Licensed tradespeople, millwrights, and mechanical contractors commonly specify this fastener type when working to ASME and ASTM standards on production or maintenance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9\/16-18 UNF fully threaded profile for fine-pitch, high-strength engagement\u003c\/li\u003e\n  \u003cli\u003e1-3\/4 inch length under head provides substantial grip length for thick material stacks\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e7\/16-inch hex socket drive accepts standard Allen wrenches and hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standards for interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-fit fastener for any application specifying a 9\/16-18 UNF hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a 7\/16-inch hex key or socket bit driver.
