Built from 18-8 stainless steel with no additional coating, this fastener measures 1-1\/2-6 UNC thread size with a 7-inch length under the head and features partial threading along the shank. The partially threaded design provides a smooth shank section that resists shear forces and allows for clamping without thread engagement through the full grip length. It is installed using a standard hex head wrench or socket driver and suits applications requiring both strength and resistance to rust, oxidation, and mild chemical exposure.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is suited for industrial, mechanical, and structural assembly work in environments where stainless steel is specified for corrosion resistance. Common applications include equipment mounting, flange bolting, pump and bracket assemblies, and outdoor or marine-adjacent installations. The UNC (Unified National Coarse) thread form makes it compatible with standard coarse-threaded nuts, inserts, and tapped holes machined to inch-series specifications. It is appropriate for both new construction fastening and maintenance or repair work across manufacturing, HVAC equipment mounting, and general mechanical trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion and oxidation resistance without a surface coating\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank improves shear strength and allows precise clamping in bolted joints\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread form is compatible with standard inch-series coarse-threaded hardware\u003c\/li\u003e\n  \u003cli\u003e7-inch length under head accommodates thick stock, stacked assemblies, or deep through-bolt applications\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates coating thickness variability and is suitable for direct contact with stainless or compatible hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series hex head cap screw for use with 1-1\/2-6 UNC coarse-threaded nuts, washers, and tapped holes conforming to Unified National Coarse thread standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fastener should be installed by a qualified mechanic or tradesperson using a properly sized hex socket or wrench to avoid rounding the head. Always inspect mating threads for damage or contamination before installation. Stainless steel fasteners are susceptible to galling during installation; applying an appropriate anti-seize compound to the threads before torquing is standard practice. Follow applicable industry codes and equipment manufacturer specifications for torque requirements on the specific assembly.\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 (Unified National Coarse)\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\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 \/ Coating\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: 2.5 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: R57001304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700386496818,"sku":"R57001304","price":81.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8a5b140e257d28bd4829bbe3bd086404.jpg?v=1788389710","url":"https:\/\/voomisupply.com\/products\/value-collection-r57001304-hex-head-cap-screw-18-8-ss","provider":"Voomi Supply","version":"1.0","type":"link"}
