It is partially threaded, conforming to ASME B18.2.1 dimensional standards. The zinc yellow dichromate finish provides a layer of corrosion resistance while serving as a visual indicator of Grade 8 strength classification. This fastener is suited for high-strength bolted assemblies and is commonly installed by millwrights, pipefitters, ironworkers, and mechanical contractors working on structural, mechanical, or equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in industrial and commercial applications requiring a high-strength fastener in 1\/2-13 UNC thread. The partial thread shank provides additional shear strength and is preferred in applications where a full thread run is not required or where precise clamping length matters. Typical install scenarios include machinery bases, structural steel connections, equipment frames, and heavy-duty brackets. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 steel construction for high tensile and proof load strength requirements\u003c\/li\u003e\n  \u003cli\u003ePartially threaded shank adds shear resistance in structural and mechanical assemblies\u003c\/li\u003e\n  \u003cli\u003eZinc yellow dichromate finish provides corrosion resistance and identifies Grade 8 classification\u003c\/li\u003e\n  \u003cli\u003e1\/2-13 UNC thread conforms to ASME B18.2.1 dimensional standards\u003c\/li\u003e\n  \u003cli\u003e5-inch length under head suits deeper grip applications where longer clamping length is needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any bolted assembly requiring a 1\/2-13 UNC Grade 8 hex head cap screw with a 5-inch length under head per ASME B18.2.1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed mechanic, millwright, or pipefitter using a standard hex socket or open-end wrench. Ensure mating threaded holes or nuts are rated for Grade 8 loading to avoid mismatched strength assemblies. Follow applicable torque specifications from the equipment manufacturer or relevant ASME or AISC guidelines. Never mix Grade 8 fasteners with lower-grade hardware in the same joint without verifying design requirements.\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\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull or Partial Threading\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 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Zinc Yellow Dichromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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\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: D39118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700890730802,"sku":"D39118","price":25.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e80dd73f25524230cc7abfab53c90a79.jpg?v=1788395389","url":"https:\/\/voomisupply.com\/products\/value-collection-d39118-hex-head-cap-screw-1-2-13-x-5-in-grade-8","provider":"Voomi Supply","version":"1.0","type":"link"}
