It features a 1-12 UNF thread with a 5-inch length under the head and a 3\/4-inch hex drive socket. Constructed from alloy steel with a black oxide coating, this screw provides solid mechanical strength and moderate corrosion resistance in controlled environments. Partially threaded along the shank, it is well-suited for applications that require a defined grip length and precise clamping force. Machinists, millwrights, and maintenance technicians are the typical installers.\u003c\/p\u003e\u003cp\u003eThis cap screw is used in both light industrial and heavy-duty mechanical assemblies where a recessed hex drive is preferred over external hex fasteners. The 1-12 UNF thread pitch is a coarse-to-fine unified thread suited for applications requiring higher thread engagement strength. The partial thread shank provides a smooth bearing surface that helps align and stabilize joined components. Common applications include machine frames, fixtures, tooling plates, and equipment enclosures where controlled torque and reliable joint integrity are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-12 UNF thread size for high thread-engagement strength\u003c\/li\u003e\n\u003cli\u003e5-inch length under head for deep-reach fastening applications\u003c\/li\u003e\n\u003cli\u003e3\/4-inch hex socket drive compatible with standard hex keys and drivers\u003c\/li\u003e\n\u003cli\u003ePartially threaded shank provides a smooth grip length for component alignment\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 mild corrosion resistance and reduced surface glare\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 1-12 UNF hex socket cap screw conforming to ASME\/ANSI B18.3 and ASTM A574 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 3\/4-inch hex key or socket driver. Always ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from your engineering drawings or fastener standards documentation, as no torque value is specified for this part. Power down and de-energize any associated equipment before accessing fastener locations on live machinery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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\u003eUNSPSC Code\u003c\/strong\u003e: 31161501\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 581691BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701798306098,"sku":"581691BR","price":25.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a0d23376975109f4389ece7554f61f64.jpg?v=1788405143","url":"https:\/\/voomisupply.com\/products\/value-collection-581691br-hex-socket-cap-screw-1-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
