Sized at 1-1\/2-6 UNC with a 5-inch length under head, this fastener is manufactured from 18-8 stainless steel and left uncoated, delivering solid corrosion resistance without any additional surface treatment. The coarse UNC thread form and partial threading make it well-suited for applications where a smooth shank section is needed between the bearing surface and the threaded engagement zone. At 2 pounds, it is a substantial fastener appropriate for high-load connections.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in a wide range of trade and industrial settings including HVAC equipment mounting, pump and compressor assemblies, pipe flange connections, and general structural fastening where corrosion resistance is a priority. The 18-8 stainless steel grade performs reliably in wet, outdoor, and mildly corrosive environments. Plumbers, pipefitters, HVAC technicians, and general mechanical contractors commonly use fasteners of this type when working with stainless or galvanized assemblies where galvanic compatibility and corrosion resistance matter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC coarse thread for high clamping force in heavy-duty assemblies\u003c\/li\u003e\n  \u003cli\u003ePartial threading allows a smooth shank section for shear-load applications\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments\u003c\/li\u003e\n  \u003cli\u003eUncoated finish maintains material integrity without plating variables\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head accommodates thick flanges, brackets, or stacked material\u003c\/li\u003e\n  \u003cli\u003eInch measurement system with standard hex head for use with common wrench sizes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard UNC hex head cap screw for use in inch-system fastener applications requiring a 1-1\/2-6 thread size and 5-inch grip length in stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic, pipefitter, or HVAC technician using the appropriate hex wrench or socket sized for a 1-1\/2-inch hex head fastener. Always verify thread engagement depth and mating thread condition before installation. Do not mix stainless steel fasteners with incompatible metals in environments prone to galvanic corrosion without appropriate isolation. Follow applicable mechanical or structural codes for torque and fastener spacing requirements.\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\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\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 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: R57001300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51703134093618,"sku":"R57001300","price":129.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5b160687f8bc94ac9bee51623977bf1e.jpg?v=1788414974","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001300-hex-head-cap-screw-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
