It features a 1-1\/4-12 UNF thread size, a 7-inch length under head, and a 7\/8-inch hex drive. Constructed from alloy steel with a black oxide coating, this cap screw delivers corrosion resistance and consistent clamping force under demanding conditions. It meets ASME\/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where fastener grade and dimensional accuracy are required. Maintenance technicians, millwrights, and industrial mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for heavy-duty mechanical assemblies, machine frames, equipment mounting, and structural fastening where a fine-thread UNF pattern provides precise torque control and resistance to loosening from vibration. The black oxide finish offers mild corrosion protection in indoor and low-exposure environments. Its partial threading allows for load distribution across the unthreaded shank in applications with close-tolerance bores or shear loading requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-12 UNF fine thread for precise engagement and vibration resistance\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head accommodates deep fastening applications\u003c\/li\u003e\n  \u003cli\u003e7\/8-inch hex socket drive for high torque input with standard allen or hex keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 high-strength requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating provides mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003ePartial threading enables shank-load distribution in close-tolerance assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style and general-purpose replacement hex socket cap screw for industrial and mechanical assemblies requiring a 1-1\/4-12 UNF partially threaded fastener conforming to ASME\/ANSI B18.3 and ASTM A574 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or millwright familiar with high-strength fastener procedures. Always verify thread engagement depth and bore condition before installation. Use a calibrated torque wrench sized for a 7\/8-inch hex drive and follow the applicable ASME or equipment manufacturer torque specifications for the fastener grade and joint material. De-energize and lock out any equipment before accessing fastener locations on live machinery.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/4-12 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 7 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: 7\/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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 581927BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51716469948722,"sku":"581927BR","price":80.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9123e3bfb718ef2db3eb0b99805c163f.jpg?v=1788526583","url":"https:\/\/voomisupply.com\/products\/value-collection-581927br-hex-socket-cap-screw-1-1-4-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
