It carries a 5\/8-11 UNC thread size with a 3.5-inch length under head, manufactured from Grade 5 steel and finished with a zinc plating for corrosion resistance. This screw meets ASME B18.2.1 dimensional standards, making it a reliable choice for applications where dimensional accuracy and load performance are required. It is installed by maintenance technicians, millwrights, pipefitters, and general tradespeople working in industrial, commercial, or light structural environments.\u003c\/p\u003e\n\u003cp\u003eThis cap screw suits a wide range of bolted joint applications where a partially threaded shank is needed to allow for controlled clamping without full thread engagement through the joint. Typical uses include equipment mounting, frame assembly, pipe support bracketing, and machinery repair. The zinc coating provides a basic level of protection against oxidation in indoor and moderate-exposure environments. It is sold individually and must be ordered in multiples of 10 to meet the minimum order quantity requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form for broad compatibility with standard inch-series nuts and tapped holes\u003c\/li\u003e\n  \u003cli\u003e3.5-inch length under head with partial threading for controlled shank clamping\u003c\/li\u003e\n  \u003cli\u003eGrade 5 steel construction for medium-strength fastening applications\u003c\/li\u003e\n  \u003cli\u003eZinc-plated finish provides basic corrosion resistance in dry to mildly humid environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.2.1 dimensional standard for hex head cap screws\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 compatible with 5\/8-11 UNC tapped holes and standard hex nuts meeting ASME B18.2.2 or equivalent specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard hex wrench or socket set sized for a 5\/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated load capacity of a Grade 5 fastener; consult applicable structural or equipment specifications before use in load-bearing or safety-critical joints. Always use an appropriate thread lubricant or anti-seize compound when assembling into tapped steel or cast iron to prevent galling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\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\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\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\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: D30145-31\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51692697354546,"sku":"D30145-31\/2","price":42.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d706f7cc4ab6ec5c289e152ebc2145cf.jpg?v=1788301352","url":"https:\/\/voomisupply.com\/products\/value-collection-d30145-31-2-hex-cap-screw-5-8-11-x-3-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
