Sized at 3\/4-16 UNF with a 4-inch length under head, this fastener is driven with a 5\/8-inch hex key. Constructed from alloy steel with a black oxide coating, it provides solid corrosion resistance and surface hardness suited to demanding conditions. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for load-bearing assemblies where material grade and dimensional accuracy matter.\u003c\/p\u003e\u003cp\u003eThis screw is used wherever a recessed hex drive cap screw is required in precision mechanical assemblies, machine frames, jigs, fixtures, or general industrial equipment. The 3\/4-16 UNF thread pitch is a fine-thread specification, offering improved torque retention and resistance to vibration loosening compared to coarse-thread alternatives. It is commonly installed by millwrights, maintenance mechanics, and industrial technicians working on equipment requiring controlled fastener engagement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eThread size: 3\/4-16 UNF fine thread for high torque retention\u003c\/li\u003e\n\u003cli\u003e4-inch length under head for deep engagement in thick workpieces\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank for precise shoulder fit in clearance holes\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduced glare\u003c\/li\u003e\n\u003cli\u003eConforms to ASME\/ANSI B18.3 dimensional standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard ASME\/ANSI B18.3 hex socket cap screw suitable for 3\/4-16 UNF tapped holes in industrial machinery, fixtures, and structural assemblies requiring alloy steel fasteners.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 5\/8-inch hex key or socket driver rated for the fastener grade. Always verify that the receiving thread is clean, properly tapped to 3\/4-16 UNF specification, and free of debris before installation. Apply appropriate thread lubricant or fastener compound per the equipment manufacturer's torque specification. Power down and de-energize any equipment before performing fastener work on live machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4 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\/ANSI B18.3 and ASTM A574\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -48549-9\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720437530930,"sku":"-48549-9","price":43.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f64f325654846e13c49d9771033210b.jpg?v=1788563936","url":"https:\/\/voomisupply.com\/products\/value-collection-48549-9-hex-socket-cap-screw-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
