Manufactured from Grade 2 uncoated steel, it meets ANSI\/ASME B18.2.1 dimensional standards. The square head profile allows wrench engagement on all four sides, making it well suited for applications where clearance limits the use of a hex head fastener. This bolt is a standard trade-supply fastener used in structural assemblies, equipment mounting, and mechanical fabrication. Installers in HVAC, plumbing, electrical, and general mechanical service will find this size a common requirement for panel and bracket attachment work.\u003c\/p\u003e\n\u003cp\u003eThe 747061PR is appropriate for general-purpose fastening applications in light to medium structural assemblies. Its uncoated steel finish is typical for indoor or protected installations where corrosion exposure is minimal. The 5\/16-18 UNC coarse thread engages quickly and resists cross-threading during installation, which is useful in field conditions. Sold individually per package, with a minimum order quantity of 50 pieces, this bolt is suited for stocking in service vans, shop inventory, or job-site supply kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC coarse thread for fast engagement and broad tool compatibility\u003c\/li\u003e\n  \u003cli\u003e3-1\/2 inch length under head provides generous grip range for thick material stacks\u003c\/li\u003e\n  \u003cli\u003eSquare head design allows four-sided wrench contact in tight or offset clearance situations\u003c\/li\u003e\n  \u003cli\u003eGrade 2 steel construction meets ANSI\/ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for dry or protected indoor installation environments\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 50 pieces supports bulk stocking and inventory replenishment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC square head bolt for general mechanical and structural fastening applications where ANSI\/ASME B18.2.1 compliant hardware is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with an open-end, box-end, or adjustable wrench sized for the square head. Apply fastener torque in accordance with the engineer of record or equipment manufacturer specification for Grade 2 steel hardware. Do not use impact drivers directly on square head bolts without a proper adapter, as this risks rounding the head. Always inspect threads for damage before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3-1\/2 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 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\/ASME B18.2.1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\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: 747061PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722815930674,"sku":"747061PR","price":5822.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6022abbdb93e502610ea53dbeb51104d_f9f9b674-a52b-40f2-a153-7654229eba70.jpg?v=1788596319","url":"https:\/\/voomisupply.com\/products\/value-collection-747061pr-square-head-bolt-5-16-18-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
