Sized at 1-1\/2-6 UNC thread with a 4-inch length under head, this fastener is manufactured from Grade 5 steel in an uncoated finish. It meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards, making it suitable for applications that require a verified tensile and proof load rating. The large diameter and coarse thread pitch provide high clamping force with good resistance to loosening under vibration and load cycling.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is used in general industrial assembly, heavy equipment maintenance, structural steel connections, and fabrication work where inch-series UNC fasteners are specified. The partial thread configuration leaves a smooth shank section under the head, which is preferred when precise shear loading through the bolt body is required or when the fastener passes through clearance holes before engaging a tapped bore or nut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread form, inch-series coarse pitch for high clamping force\u003c\/li\u003e\n  \u003cli\u003e4-inch length under head, partially threaded for shank-bearing applications\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction meeting SAE J429 mechanical property requirements\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use as-is or with field-applied corrosion protection\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an inch-series UNC replacement or service fastener for heavy equipment, structural assemblies, and industrial machinery that specify a 1-1\/2-6 Grade 5 hex head cap screw per ASME B18.2.1 or SAE J429.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, millwright, or structural ironworker familiar with large-diameter fastener torque procedures. Always verify thread engagement depth and hole clearance before assembly. Apply appropriate thread lubricant or anti-seize compound if specified by the equipment manufacturer. Follow applicable industry standards and engineering specifications for torque values, as no torque data is supplied with this fastener.\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\/2-6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 4 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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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\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: 97257\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696654745906,"sku":"97257","price":56.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/488ce64999e03332e472148f19a7e556.jpg?v=1788344849","url":"https:\/\/voomisupply.com\/products\/value-collection-97257-hex-head-cap-screw-grade-5-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
