It features a 3\/4-16 UNF thread size with full threading along its 2-3\/4 inch length under head, providing maximum thread engagement for demanding load applications. The screw is manufactured from alloy steel and finished with black oxide coating, which offers mild corrosion resistance and reduces surface reflectivity. The 5\/8 inch hex drive socket interface allows installation with standard hex keys or socket drivers. This fastener conforms to ASME B18.3 and ASTM A574 standards, confirming dimensional and mechanical property compliance for critical fastening use.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for machinery assembly, equipment mounting, structural fastening, and maintenance work across industrial, HVAC, plumbing, and mechanical contracting applications. It is appropriate for use in ferrous and non-ferrous assemblies where a high-strength, fine-thread fastener with a low-profile socket head is required. The fine UNF thread pitch provides improved torque control and better resistance to loosening under vibration compared to coarse-thread equivalents, making it a common choice in precision-fit assemblies and close-tolerance applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF fine thread for improved vibration resistance and torque control\u003c\/li\u003e\n  \u003cli\u003eFully threaded 2-3\/4 inch length under head for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch hex socket drive for use with standard hex keys or socket drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion protection 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 replacement or standard-service fastener for applications requiring a 3\/4-16 UNF hex socket cap screw conforming to ASME B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical contractors, millwrights, or qualified trade technicians using a calibrated torque wrench and the appropriate 5\/8 inch hex key or socket. Always de-energize and lock out equipment before replacing or installing structural fasteners per applicable safety procedures. Ensure mating threads are clean and free of debris before installation. Do not mix thread standards  -  confirm the mating component is also UNF before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 2-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully 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\u003eWeight\u003c\/strong\u003e: 0.46 pounds\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\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: 730003140\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51780728652082,"sku":"730003140","price":16.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/748c1b872e39ccd58795baac28c40909.jpg?v=1789176231","url":"https:\/\/voomisupply.com\/products\/holo-krome-730003140-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
