It features a 1-1\/4-7 UNC thread size and measures 5-1\/2 inches under the head. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener provides corrosion resistance suitable for general industrial and construction applications. It conforms to ASME B18.2.1 and SAE J429 standards, making it appropriate for use in code-sensitive installations. Machinists, millwrights, pipefitters, and general maintenance tradespeople are the typical installers of this hardware.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for a wide range of inch-system fastening applications where a large-diameter, partially threaded bolt is required. The partial threading allows the unthreaded shank to serve as a precision-fit bearing surface in bolted joints, which is common in equipment mounting, structural steel connections, and heavy machinery assembly. The zinc coating adds a layer of protection against light moisture and oxidation in indoor or semi-sheltered environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-7 UNC thread for high-load, coarse-thread engagement\u003c\/li\u003e\n  \u003cli\u003e5-1\/2 inches under head — partial threading leaves an unthreaded shank for precision-fit joints\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets SAE J429 and ASME B18.2.1 standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for general-use environments\u003c\/li\u003e\n  \u003cli\u003eInch measurement system — compatible with standard UNC tooling and hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or general-use fastener for applications requiring a 1-1\/4-7 UNC partially threaded hex head cap screw conforming to ASME B18.2.1 and SAE J429 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified tradesperson using properly sized hex wrenches or impact sockets rated for the fastener diameter. Always ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before replacing fasteners in live mechanical assemblies. Do not exceed the rated load capacity for Grade 2 fasteners in high-tension structural applications where Grade 5 or Grade 8 hardware may be specified.\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\/4-7 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5-1\/2 inches\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Grade 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASME B18.2.1, SAE J429\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12588CH2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51697828004146,"sku":"12588CH2","price":43.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f9ee40753e54e60ffec02728163aa55.jpg?v=1788354693","url":"https:\/\/voomisupply.com\/products\/value-collection-12588ch2-hex-head-cap-screw-1-1-4-7","provider":"Voomi Supply","version":"1.0","type":"link"}
