With a 1-12 UNF thread and a 3\/4-inch hex drive, this cap screw delivers the torque capacity and thread engagement needed for demanding applications. The 3.5-inch length under head suits installations requiring deeper grip in structural or machine components. Made from alloy steel with a black oxide finish, it provides reliable corrosion resistance in moderate environments. Licensed trades and maintenance professionals specify this fastener type for machinery, fixtures, and equipment where a clean, recessed drive is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in industrial machinery, fabricated steel structures, jigs, fixtures, and mechanical assemblies where a partially threaded, high-strength cap screw is the correct specification. The 1-12 UNF thread pitch indicates a fine-thread application, typically used where vibration resistance or precise thread engagement in thin or hardened material is a priority. Installation is performed by maintenance technicians, millwrights, or mechanical contractors working to ASME and ASTM fastener standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-12 UNF fine thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hex socket drive accommodates standard hex keys and socket drivers\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head for deeper fastening reach in structural applications\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank provides shear strength and alignment in bolted joints\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASME\/ANSI B18.3 and ASTM A574 standards\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish offers moderate corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct specification fastener for industrial machinery and mechanical assemblies requiring a 1-12 UNF hex socket cap screw per ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by millwrights, mechanical technicians, or industrial maintenance professionals. Ensure mating threads are clean and free of debris before installation. Use a calibrated torque wrench with the correct 3\/4-inch hex bit to achieve the specified clamp load for this thread size and material grade. Do not mix UNF and UNC fasteners in the same tapped hole, as thread form incompatibility will cause damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-12 UNF\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: Partially Threaded\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\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: 581681PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51718145671474,"sku":"581681PR","price":21.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/95de8fc23e102f34edd363311303e721.jpg?v=1788550314","url":"https:\/\/voomisupply.com\/products\/value-collection-581681pr-hex-socket-cap-screw-1-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
