It conforms to ASME B18.13, the standard governing slotted and recessed pan head screws. The pan head profile provides a wide bearing surface and low-profile appearance, while the Phillips recess allows for positive driver engagement. The 18-8 stainless steel construction delivers corrosion resistance suitable for both indoor and outdoor applications. Length is measured under the head at 5\/8 inch. This fastener is sold as a minimum order quantity of 100 pieces per package, making it appropriate for production, assembly, and maintenance stockrooms.\u003c\/p\u003e\u003cp\u003eThis screw is used in light-duty mechanical assemblies, electrical enclosures, HVAC control panels, and general sheet metal or plastic component fastening where a small-diameter, corrosion-resistant fastener is required. The 4-40 thread size is common in electronic and instrumentation assemblies. Technicians and assemblers working on control boards, junction boxes, and equipment panels will recognize this as a standard fastener for securing covers, brackets, and small components. It is appropriate for both original equipment assembly and field service repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e18-8 stainless steel construction for corrosion resistance in wet or humid environments\u003c\/li\u003e\n\u003cli\u003ePan head profile with wide bearing surface and low-profile seating\u003c\/li\u003e\n\u003cli\u003ePhillips drive for positive engagement with standard and power drivers\u003c\/li\u003e\n\u003cli\u003eConforms to ASME B18.13 fastener standard\u003c\/li\u003e\n\u003cli\u003eExternal tooth washer style for added holding capability\u003c\/li\u003e\n\u003cli\u003eLength under head: 5\/8 inch, measured per ASME B18.13 convention\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4-40 machine screw compatible with any tapped 4-40 threaded hole or nut conforming to Unified National Coarse thread specifications in the inch measurement system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a Phillips screwdriver or bit driver sized for a number 4 screw head. Verify the mating thread is tapped to 4-40 UNC before installation to avoid cross-threading. Power down any electrical equipment before fastening or removing screws in control panels or enclosures. Do not overtighten stainless steel fasteners in stainless or aluminum tapped holes, as galling can occur — apply consistent, controlled torque using hand tools when possible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/8 inch\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\u003eWasher Style\u003c\/strong\u003e: External 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\u003eMeasurement System\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: W98256PS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691994841394,"sku":"W98256PS","price":4588.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d294a9c63a40b339a7bce5615b17854b.jpg?v=1788291858","url":"https:\/\/voomisupply.com\/products\/value-collection-w98256ps-4-40-x-5-8-pan-head-phillips-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
