Manufactured from Grade 5 steel with a zinc-plated finish, this fastener meets ASME B18.2.1 and SAE J429 standards for dimensional accuracy and tensile strength. The 1-8 thread size follows Unified National Coarse (UNC) specifications, and the 3-inch length is measured under the head. The zinc plating provides a baseline level of corrosion resistance suitable for indoor and sheltered environments. Sold in a package quantity of 20 per order.\u003c\/p\u003e\n\u003cp\u003eThis hex head cap screw is suited for use in structural assemblies, equipment mounting, and mechanical connections where a Grade 5 fastener is specified. Partial threading allows the unthreaded shank to act as a shoulder or locating surface, making it appropriate for joint connections where shear load distribution matters. Typical applications include HVAC equipment mounting frames, plumbing support brackets, electrical panel mounting, and general mechanical equipment assembly in both residential and light commercial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction meets SAE J429 and ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides corrosion resistance for sheltered or indoor use\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank suits applications requiring a shoulder or shear surface\u003c\/li\u003e\n  \u003cli\u003e1-8 UNC thread size for compatibility with standard coarse-thread nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3-inch length measured under the head per ASME B18.2.1 convention\u003c\/li\u003e\n  \u003cli\u003ePackage quantity of 20 supports job-lot use without excess inventory\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 1-8 UNC tapped holes or matching nuts in mechanical and structural assemblies conforming to ASME B18.2.1 and SAE J429 requirements.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a mechanic, pipefitter, electrician, or HVAC technician depending on the application. Always match the nut or tapped hole thread class to the fastener before assembly. Ensure mating surfaces are clean and free of debris before driving. Do not substitute a lower-grade fastener where Grade 5 is specified by equipment manufacturer torque and load tables.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 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: 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: Zinc-Plated\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\u003ePackage Quantity\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: -30170-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710942019890,"sku":"-30170-3","price":117.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66209f10054e6dd491471a7f41eb32a8.jpg?v=1788472646","url":"https:\/\/voomisupply.com\/products\/value-collection-30170-3-hex-cap-screw-1-8x3-grade-5","provider":"Voomi Supply","version":"1.0","type":"link"}
