Zinc plating provides corrosion resistance in standard indoor and light outdoor service conditions. The fastener is partially threaded, which helps maintain clamping force across unthreaded shank sections — a common requirement in structural and mechanical bolted joints. Supplied in a 10-piece pack, this screw meets ASME B18.2.1 dimensional standards, making it suitable for use in applications where dimensional conformance is specified. Installers in HVAC, plumbing, and general mechanical work will recognize this as a standard heavy-hex grade fastener used throughout equipment mounting, structural brackets, and access panel assemblies.\u003c\/p\u003e\n\u003cp\u003eThis cap screw is appropriate for a wide range of commercial and industrial fastening applications where a coarse-thread, medium-strength steel fastener is specified. Typical uses include equipment bases, structural steel connections, mechanical supports, conduit and duct hangers, fan assemblies, and general maintenance work. The 1\/2-13 UNC thread is one of the most common coarse-thread sizes in North American trade work, making this fastener easy to pair with standard hex nuts, flat washers, and lock washers available across the trade supply channel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 5 steel construction provides medium-strength tensile performance suitable for general mechanical and structural bolted joints\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish offers corrosion resistance for standard service environments\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank maintains clamping force and prevents thread engagement through thin members\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC (Unified National Coarse) thread is a widely stocked standard size compatible with common hex nuts and hardware\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standards for hex head cap screws\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-piece pack for job-lot convenience\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 1\/2-13 UNC hex nuts, flat washers, and lock washers.

Always de-energize equipment and relieve system pressure before replacing or tightening fasteners on live mechanical assemblies. Torque to the value specified in the equipment manufacturer's documentation or the applicable structural specification — do not substitute general torque estimates. Reuse of fasteners removed from high-cycle or high-load joints is not recommended without inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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 (Unified National Coarse)\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\u003eDimensional Standard\u003c\/strong\u003e: ASME B18.2.1\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: 10 pieces\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: MP30112\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689462497586,"sku":"MP30112","price":21.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebd5445e7247681b95fec3cc81f3011d.jpg?v=1788259846","url":"https:\/\/voomisupply.com\/products\/value-collection-mp30112-hex-head-cap-screw-1-2-13-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
