Featuring a 7\/8-9 UNC thread and a 3\/4-inch hex drive, this cap screw is partially threaded with a 3.5-inch length under the head. The alloy steel construction is finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection in service environments. It conforms to ASME B18.3 and ASTM A574 standards, making it a recognized choice for engineers and maintenance technicians specifying high-tensile socket head fasteners.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for use in machine tool assemblies, heavy equipment, jigs and fixtures, die sets, and structural connections where a flush or recessed fastener head is required. The hex socket drive allows installation in confined spaces where a wrench or open-end tool cannot reach. Maintenance professionals, millwrights, and industrial mechanics typically install this fastener during equipment builds, retrofits, or field repairs requiring ASME B18.3-compliant hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-9 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head with partial threading for strong clamping grip\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive for use with standard Allen or hex-key tooling\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meeting ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-glare appearance\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.3 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and replacement hex socket cap screw for applications requiring 7\/8-9 UNC inch-series threading and ASME B18.3 or ASTM A574 compliance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by millwrights, machinists, or maintenance technicians using a 3\/4-inch hex key or Allen-drive socket tool. Verify that the mating tapped hole is clean, properly sized to 7\/8-9 UNC specification, and free of debris before threading. Apply thread lubricant or anti-seize compound as required by the assembly specification. Do not exceed the torque rating specified by the equipment manufacturer or applicable fastener standard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-9 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 inches\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: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Partial\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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 72350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51741028614450,"sku":"72350","price":27.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/966a8ed8e7ad0f977254c8e4b9b1f426.jpg?v=1788828967","url":"https:\/\/voomisupply.com\/products\/holo-krome-72350-hex-socket-cap-screw-7-8-9-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
