It meets ASME B18.6.3 and SAE J82 standards, making it a reliable choice for general-purpose fastening applications in light industrial, mechanical, and assembly work. The round head profile provides a low-clearance, finished appearance above the mating surface. The Phillips drive allows for quick installation with standard hand tools or power drivers. Length is measured under the head. This screw is sold individually but must be ordered in multiples of 10.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in general mechanical assembly, equipment fabrication, and light structural fastening where a 5\/16-18 unified coarse thread is specified. It is appropriate for use in applications that do not require a washer face or washer under the head. Electricians, millwrights, plumbers, and general maintenance technicians commonly use this fastener size in panel mounting, bracket attachment, and equipment assembly tasks. Always verify thread engagement depth and mating material before selecting fastener length.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 unified coarse thread for broad compatibility with standard tapped holes and nuts\u003c\/li\u003e\n  \u003cli\u003e4 inch length measured under the head for accurate installation planning\u003c\/li\u003e\n  \u003cli\u003eRound head profile with Phillips drive for use with standard bits and power drivers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for corrosion resistance in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eMeets ASME B18.6.3 and SAE J82 standards for dimensional and mechanical consistency\u003c\/li\u003e\n  \u003cli\u003eNo washer face — designed for applications where a flat bearing surface is sufficient\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 5\/16-18 unified coarse thread machine screw with a round head Phillips drive in the inch measurement system.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Phillips screwdriver or Phillips-tip power driver of the appropriate size to avoid cam-out and head damage. Ensure the mating hole is properly tapped to 5\/16-18 UNC before driving. Do not overtighten — follow the torque requirements of the assembly design. For outdoor or high-moisture environments, evaluate whether the zinc finish provides sufficient corrosion protection for the application.\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\u003eLength\u003c\/strong\u003e: 4 inches (measured under head)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.6.3, SAE J82\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  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161504\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: 588753PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51694321991986,"sku":"588753PR","price":1733.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5c749d24d33fe38fd6103edb4513d0c3.jpg?v=1788323090","url":"https:\/\/voomisupply.com\/products\/value-collection-588753pr-5-16-18x4-round-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
