Machined from alloy steel and finished with a black oxide coating, this fastener delivers solid corrosion resistance and a consistent surface hardness suited to demanding environments. The screw measures 4.5 inches in length under the head with a 7\/8-14 UNF thread size, providing fine-thread engagement for applications where vibration resistance and precise clamping load are required. Drive type is hex socket, accepting a 3\/4-inch drive tool for installation and removal.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for use in machinery assembly, heavy equipment maintenance, and general industrial fabrication where alloy steel fasteners meeting ASME\/ANSI B18.3 and ASTM A574 standards are specified. The 7\/8-14 UNF thread form is a fine-pitch unified thread, commonly selected in metal-to-metal joints where thread stripping resistance and controlled preload are priorities. Machinists, millwrights, maintenance technicians, and mechanical contractors are the typical installers of this fastener type.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/8-14 UNF fine thread for precise torque control and vibration resistance\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank allows for shoulder bearing load in clearance-hole applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive for use with standard hex keys or socket drive tooling\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 dimensional standards for socket cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for any application calling for a 7\/8-14 UNF partially threaded alloy steel fastener with a 3\/4-inch hex drive.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or technician using a calibrated hex socket or hex key sized at 3\/4 inch. Ensure mating threads are clean and free of debris before engagement to prevent cross-threading. Apply thread lubricant or thread-locking compound as specified by the equipment manufacturer. De-energize and lock out all affected machinery before replacing or installing fasteners in powered assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4.5 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: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 581792BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697690509618,"sku":"581792BR","price":19.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2816fc3ea1a0de3ebbded6c00312548_9c5a894f-ab97-4efc-a619-1b12fb377720.jpg?v=1788354119","url":"https:\/\/voomisupply.com\/products\/value-collection-581792br-hex-socket-cap-screw-7-8-14-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
