It features a round head profile with a slotted drive, a thread size of 5-40, and a length under head of 0.5 inches. The fastener is manufactured from steel with a zinc finish applied for basic corrosion resistance. It conforms to ASME B18.6.3 and SAE J82 standards. These screws are sold in lots and are a standard item for technicians, assemblers, and maintenance professionals working on light-duty mechanical, electrical panel, or instrument enclosure assemblies.\u003c\/p\u003e\n\u003cp\u003eThis machine screw is suited for use in residential and commercial maintenance, light fabrication, and service applications where a compact, round-head slotted fastener is required. The 5-40 thread size is commonly found in small instrument panels, electrical enclosures, control boxes, and electronic equipment housings. A standard flat-blade screwdriver or slotted bit is all that is needed for installation. The screw has no washer and is measured length under head per ASME B18.6.3.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 5-40 unified fine thread for precise engagement in tapped holes\u003c\/li\u003e\n  \u003cli\u003eRound head profile provides a low-profile, finished appearance on panel surfaces\u003c\/li\u003e\n  \u003cli\u003eSlotted drive compatible with standard flat-blade screwdrivers and bits\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc finish for basic corrosion protection in dry environments\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME B18.6.3 and SAE J82 fastener standards\u003c\/li\u003e\n  \u003cli\u003eNo washer style simplifies installation in tight or flush-mount applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 5-40 round head slotted machine screw per ASME B18.6.3 and SAE J82, suitable for use in any application requiring a 5-40 tapped hole with a 0.5-inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by hand or with a flat-blade screwdriver or slotted power bit. Always verify the receiving hole is tapped to the correct 5-40 thread specification before driving the fastener to avoid cross-threading. Do not overtorque, as small-diameter machine screws are susceptible to thread stripping in soft substrates. Power down or de-energize any panel or enclosure before installing fasteners in live electrical assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Round Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.5 inches\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 Coating\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\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: 0508MSR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721844785458,"sku":"0508MSR","price":774.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/153d202d2e5772fea9cb3d9ce1331667.jpg?v=1788581834","url":"https:\/\/voomisupply.com\/products\/value-collection-0508msr-5-40-x-0-5-in-round-head-slotted-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
