Sized at 4-40 UNC with a 1\/4 inch length under head and a 3\/32 inch hex drive, this screw is fully threaded and manufactured from alloy steel with a black oxide finish. The black oxide coating provides a degree of corrosion resistance while reducing light reflection, which is useful in instrumentation, electronics enclosures, and close-tolerance mechanical assemblies. This package contains 50 screws. Machinists, maintenance technicians, and electromechanical assembly workers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThese socket cap screws are suited for applications where a low-profile, high-strength fastener is needed in tight clearance conditions. The 4-40 UNC thread designation is common in light-duty machine assemblies, electronic chassis, jigs, fixtures, and precision instruments. The 3\/32 inch hex drive requires a matching hex key or Allen driver for installation. Fully threaded along the shank length, these screws provide maximum thread engagement for their size, making them appropriate for shallow through-hole and tapped-hole applications in metal and rigid plastic components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread size for use in standard inch-series tapped holes\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch length under head — fully threaded for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive for use with standard Allen keys\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for higher strength than standard steel fasteners\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 50-piece package — practical quantity for small-batch production or repair stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series socket cap screw compatible with any application requiring a 4-40 UNC tapped hole and a 1\/4 inch length under head fastener per ANSI B18.3 specification.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 3\/32 inch hex key or T-handle Allen driver. Ensure the mating tapped hole conforms to 4-40 UNC thread form before driving the screw to avoid cross-threading. Torque to the assembly specification established for the application and base material — do not exceed the rated capacity of the alloy steel fastener or the strength of the mating material. Depressurize, de-energize, or otherwise make safe any assembly before removing or replacing fasteners in service.\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\u003eLength Under Head\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\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: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standards\u003c\/strong\u003e: ANSI B18.3, ANSI B18.8.2, ANSI B2.2, MS16555\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 50 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: MP72018\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698527502642,"sku":"MP72018","price":18.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_7f3abe2b-adc6-4301-9961-60aa3a8d7493.jpg?v=1788364242","url":"https:\/\/voomisupply.com\/products\/value-collection-mp72018-hex-socket-cap-screw-4-40-unc-50pk","provider":"Voomi Supply","version":"1.0","type":"link"}
