It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a consistent matte appearance. This fastener meets ASME B18.3 and ASTM A574 standards, making it appropriate for high-strength structural and mechanical assembly applications. Maintenance technicians, millwrights, and industrial contractors install this type of screw where reliable clamping force and socket-drive access are required.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy industrial, mechanical, and structural installations where a 3\/4-10 UNC threaded connection is specified. Partial threading allows the unthreaded shank to act as a precision locating or shear element in close-tolerance assemblies. The black oxide finish is commonly selected for indoor mechanical environments, tooling fixtures, machine frames, and equipment mounts where light oil retention helps maintain surface protection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-10 UNC thread size for compatibility with standard coarse-thread tapped holes\u003c\/li\u003e\n  \u003cli\u003e9-1\/2 inch length under head accommodates deep-grip or stacked-material assemblies\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear resistance and precise location in critical joints\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength fastener requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish reduces light reflection and offers mild surface protection\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch hex socket drive works with standard Allen or hex-key tooling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and aftermarket replacement hex socket cap screw for applications requiring a 3\/4-10 UNC, 9-1\/2 inch partially threaded fastener conforming to ASME B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified millwright, maintenance mechanic, or industrial technician using a calibrated torque wrench and the appropriate 5\/8 inch hex key or socket driver. De-energize and lock out all equipment before fastener removal or installation per applicable OSHA lockout\/tagout procedures. Do not substitute a shorter fastener where this length is structurally specified. Apply thread lubricant or anti-seize only if specified by the equipment manufacturer, as lubrication affects torque-tension relationships.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-10 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 9-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partially Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.28 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 720003356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51742265508146,"sku":"720003356","price":84.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e021ca9ef64ab2fe4460a544a2b437f5.jpg?v=1788836317","url":"https:\/\/voomisupply.com\/products\/holo-krome-720003356-hex-socket-cap-screw-3-4-10-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
