Built to Grade 5 steel specification, it delivers reliable tensile strength for bolted assemblies where medium-strength carbon steel is specified. The zinc-plated finish provides a base level of corrosion resistance suitable for interior and light-duty service environments. At 3.5 inches under the head with a 1-8 UNC thread, this fastener is well suited to structural bolted connections, equipment framing, and machinery assembly work across mechanical and light fabrication trades.\u003c\/p\u003e\u003cp\u003eThis hex head cap screw is appropriate for residential and commercial mechanical applications where UNC inch-series fasteners are required. The partial threading leaves a smooth shank section that helps resist shear loading in clearance-hole applications. Tradespeople working in HVAC equipment mounting, plumbing rough-in framing, and general mechanical installations will find this fastener compatible with standard hex driver tooling and torque specifications for Grade 5 hardware. Packaged in quantities of 20, it suits bench-stock replenishment and job-site use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 5 steel construction for medium-strength fastening requirements\u003c\/li\u003e\n\u003cli\u003eZinc-plated finish offers basic corrosion protection in dry or low-moisture environments\u003c\/li\u003e\n\u003cli\u003ePartial threading provides a smooth shank for shear-resistant bolted joints\u003c\/li\u003e\n\u003cli\u003e1-8 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n\u003cli\u003e3.5-inch length under head suits deep-grip bolted assemblies and thick-material connections\u003c\/li\u003e\n\u003cli\u003ePackaged in quantities of 20 for bench-stock and service-truck replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard inch-series UNC threaded assemblies requiring a Grade 5 hex head cap screw with a 1-8 thread and 3.5-inch grip length.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified mechanical or trade personnel using an appropriately sized hex wrench or socket driver. Apply Grade 5 torque values per applicable ASME or equipment manufacturer specifications; do not substitute these fasteners in applications requiring Grade 8 or metric-grade hardware. Inspect the mating nut or tapped hole for thread condition before installation. Follow applicable codes and lockout\/tagout procedures when fastening components on energized or pressurized equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3.5 inches\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\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: -30170-31\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717536186674,"sku":"-30170-31\/2","price":133.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f01adbae8474ee5d9ef715a04212bef5.jpg?v=1788542086","url":"https:\/\/voomisupply.com\/products\/value-collection-30170-31-2-hex-head-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
