Manufactured from alloy steel with a black oxide finish, this cap screw meets the dimensional and mechanical requirements of ASME\/ANSI B18.3 and ASTM A574. The 1-1\/4-12 UNF thread profile provides fine-pitch engagement suited to applications where vibration resistance and precise clamping load are critical. With a 3.5-inch length under head and a 7\/8-inch hex socket drive, this fastener is sized for heavy-duty assemblies requiring reliable torque transfer. Machinists, millwrights, and industrial maintenance technicians are the typical installers of this fastener class.\u003c\/p\u003e\u003cp\u003eThis cap screw is appropriate for use in mechanical assemblies, industrial equipment, and structural fixturing where alloy steel strength and a fine UNF thread are specified. The black oxide coating provides mild corrosion resistance and reduces light reflection on installed components. It is suited to both original equipment assembly and field maintenance work in manufacturing, heavy equipment, and industrial plant environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/4-12 UNF fine-pitch thread for precise clamping and vibration resistance\u003c\/li\u003e\n\u003cli\u003eFully threaded along the shank for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating for mild corrosion resistance and surface protection\u003c\/li\u003e\n\u003cli\u003e7\/8-inch hex socket drive for high-torque installation with standard tooling\u003c\/li\u003e\n\u003cli\u003eComplies with ASME\/ANSI B18.3 dimensional standards\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 any application specifying a 1-1\/4-12 UNF fully threaded alloy steel fastener conforming to ASTM A574.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists or maintenance technicians familiar with high-strength fastener procedures. Use a calibrated torque wrench with a 7\/8-inch hex socket driver and follow the torque specifications required by the equipment manufacturer or applicable engineering standard. Ensure mating threaded holes are clean and free of debris before installation. Do not use impact drivers without verifying that torque output is controlled and within the fastener grade requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 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: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\u003c\/strong\u003e: Fully Threaded\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: 0.01 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: 581915BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693273252146,"sku":"581915BR","price":58.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/18fc6219d468300f1154053c18b27c34.jpg?v=1788310004","url":"https:\/\/voomisupply.com\/products\/value-collection-581915br-hex-socket-cap-screw-1-1-4-12-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
