The screw measures 3\/4 inches in length, measured under the head. It is manufactured from alloy steel and finished with a zinc plating for basic corrosion resistance in dry indoor environments. These fasteners are used across light assembly, panel mounting, and component attachment tasks common in electrical, HVAC, and general mechanical work. They ship without a washer and conform to inch-standard (UNC) threading.\u003c\/p\u003e\n\u003cp\u003eThese screws are suited for light-duty fastening applications where a 4-40 thread is specified. Typical uses include securing terminal blocks, control board mounting brackets, small electrical enclosure components, and instrument panels. The slotted round head provides a low-profile bearing surface and is compatible with standard flathead screwdrivers. The zinc plating is appropriate for indoor or protected installations where moderate handling resistance is required. The 100-count box format supports bench stock replenishment and service truck inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/4 inch length under head for consistent grip in typical panel and bracket applications\u003c\/li\u003e\n  \u003cli\u003eRound head profile with slotted drive for use with standard flathead screwdrivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction provides strength suitable for light mechanical fastening\u003c\/li\u003e\n  \u003cli\u003eZinc plating offers basic corrosion resistance in dry indoor environments\u003c\/li\u003e\n  \u003cli\u003eSupplied without washer — no washer removal or substitution required at install\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series machine screw for any application requiring a 4-40 UNC thread, round head, and slotted drive in alloy steel with zinc finish.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a standard flathead screwdriver sized to the slotted head. Power down or de-energize any equipment before fastening components inside electrical enclosures or control panels, in accordance with applicable NFPA 70 (NEC) lockout\/tagout procedures. Do not overtighten — alloy steel screws at this thread size have limited torque tolerance in softer tapped materials such as aluminum or plastic. Verify thread engagement depth matches the tapped hole to prevent stripping.\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 UNC\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: Slotted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWasher Style\u003c\/strong\u003e: Without Washer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound (per box)\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: MSRI0-400750-100BX\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51709918019890,"sku":"MSRI0-400750-100BX","price":455.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf62607c31df816ffda44bbcdf177734.jpg?v=1788462271","url":"https:\/\/voomisupply.com\/products\/value-collection-msri0-400750-100bx-machine-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
