It conforms to ASME B18.6.3 and SAE J82 standards, making it a reliable choice for general mechanical assembly applications. The fillister head profile offers a smaller outer diameter and taller head height compared to a pan head, which suits installations where lateral clearance is limited or a deep slot engagement is needed. This fastener ships without an integrated washer. Licensed trade mechanics, millwrights, pipefitters, and maintenance technicians commonly source this screw for equipment reassembly and structural fastening tasks.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for use in light to medium-duty mechanical assemblies, equipment enclosures, and general industrial maintenance applications where a 5\/16-18 UNC thread is specified. The 3-inch length under head provides adequate grip range for multi-layer material stacks or thicker structural members. The zinc finish provides a base level of corrosion resistance appropriate for indoor and sheltered environments. Sold individually per package; minimum order quantity is 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread with 3-inch length under head for solid engagement in thicker assemblies\u003c\/li\u003e\n  \u003cli\u003eFillister head profile provides reduced outer diameter and deep slotted recess for secure drive engagement\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers and manual bit drivers\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for base corrosion resistance in dry or sheltered environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eNo integrated washer style — clean seating on flat surfaces without a flange footprint\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5\/16-18 UNC fillister head machine screw per ASME B18.6.3, suitable as a replacement or stock fastener in any application calling for this thread size, head type, and drive style.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a flat-blade screwdriver or slotted bit sized for a 5\/16-inch fillister head. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid cross-threading or drive slot damage. Follow applicable torque guidelines from the equipment manufacturer or relevant ASME standards for Grade J82 steel fasteners. Do not use impact drivers without appropriate torque control, as slotted drive recesses are susceptible to cam-out under high torque.\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 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Fillister\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\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: J82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc\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: 0.0618 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: 5\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: 3148MSL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51700402651442,"sku":"3148MSL","price":898.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c95954702f9de8ffa343e15282a5f026.jpg?v=1788389895","url":"https:\/\/voomisupply.com\/products\/value-collection-3148msl-machine-screw-5-16-18-x-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
