This screw features a 3\/4-16 UNF thread size with a 5-1\/2 inch length under head and a partially threaded shank. The 5\/8 inch hex drive allows torque application with standard hex keys or allen drivers. Constructed from alloy steel with a black oxide finish, it offers corrosion resistance and durability under load. Manufactured to ASME B18.3 and ASTM A574 standards, it meets the dimensional and mechanical requirements expected by professional tradespeople and engineers alike.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for mechanical assemblies, equipment fabrication, and structural fastening where a recessed drive head and high tensile alloy steel construction are required. It is commonly installed in machinery frames, jigs, fixtures, and heavy-duty assemblies across manufacturing, HVAC equipment manufacturing, and general industrial maintenance. The partially threaded shank provides positive clamping without thread engagement through the full grip length, which is important in bolted joint applications requiring precise clamp load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/4-16 UNF thread for fine-pitch, high-strength fastening\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inch length under head with partial threading for proper clamping grip\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch hex socket drive compatible with standard hex keys and drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME 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 direct-use fastener for applications requiring a 3\/4-16 UNF hex socket cap screw per ASME B18.3 and ASTM A574 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or tradesperson using an appropriately sized 5\/8 inch hex key or socket driver. De-energize and lock out all equipment before removing or installing fasteners in mechanical assemblies. Apply thread lubricant or thread-locking compound as required by the assembly specification to achieve correct clamp load. Always verify thread engagement depth and avoid cross-threading when starting the fastener by hand before applying torque.\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: 5.5 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: 5\/8 inch\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: 0.8 pounds\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: 730003280\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51787560714546,"sku":"730003280","price":21.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec8026f2e5730edecd7062f918fe3e62.jpg?v=1789216619","url":"https:\/\/voomisupply.com\/products\/holo-krome-730003280-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
