Designed for precision fastening in light-duty mechanical assemblies, enclosures, and electrical panels, this screw features an internal tooth washer style for added locking capability under the head. The 5\/16 inch length is measured under the head per standard convention. Sold in minimum order quantities of 100 units, this fastener suits production environments, MRO stockrooms, and bench-level assembly work where corrosion resistance and consistent thread engagement are required.\u003c\/p\u003e\n\u003cp\u003eThe W98452PS fits applications where a 4-40 unified coarse thread is specified, including instrument housings, control panel assembly, light electronic enclosures, and small appliance fabrication. The pan head profile provides a broad bearing surface suited to through-hole and tapped-hole installations in sheet metal and plastic substrates. Stainless steel construction makes this screw appropriate for environments with moderate moisture exposure where carbon steel fasteners would corrode. This fastener is installed by mechanical assemblers, electricians, and electronics technicians as part of standard fastening practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 unified thread with 5\/16 inch length under head for precise fit in tapped assemblies\u003c\/li\u003e\n  \u003cli\u003e18-8 stainless steel construction provides corrosion resistance in wet or outdoor-adjacent environments\u003c\/li\u003e\n  \u003cli\u003ePan head profile delivers wide clamping surface and low-profile clearance above the workpiece\u003c\/li\u003e\n  \u003cli\u003ePhillips drive compatible with standard Number 1 Phillips screwdrivers and power drivers\u003c\/li\u003e\n  \u003cli\u003eInternal tooth washer style adds vibration resistance without a separate lock washer\u003c\/li\u003e\n  \u003cli\u003eManufactured to ASME B18.13 ensuring consistent dimensional and mechanical tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fastener for any assembly specifying a 4-40 x 5\/16 inch pan head Phillips machine screw per ASME B18.13 in inch measurement.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a Number 1 Phillips screwdriver or a properly sized power driver bit to avoid cam-out and head damage. Ensure mating threads are clean and free of debris before driving. When installing into tapped holes in thin materials, verify thread engagement depth meets the requirements of the applicable assembly standard. Stainless steel fasteners are susceptible to galling during installation — apply an appropriate anti-seize compound when torque consistency is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Pan Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Phillips\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Internal Tooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 18-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME B18.13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.052 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: W98452PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51717592613170,"sku":"W98452PS","price":3856.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60d6aa286e09d60a790d0c7da4d9cc92.jpg?v=1788543024","url":"https:\/\/voomisupply.com\/products\/value-collection-w98452ps-4-40-x-5-16-pan-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
