Manufactured from alloy steel with a black oxide finish, this screw offers improved corrosion resistance and reduced light reflection compared to bare steel. The 3\/32-inch internal hex drive accepts a standard hex key or Allen wrench. The screw is fully threaded along its 3\/4-inch length under head, maximizing thread engagement across the full grip range. This fastener is suitable for use by machinists, maintenance technicians, and assembly professionals working with metal fabrication, instrumentation, or mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis cap screw is suited for applications requiring a low-profile, recessed fastener in 4-40 UNC tapped holes. Typical uses include panel mounting, jig and fixture assembly, instrument enclosures, and light mechanical assemblies where space constraints prevent the use of a standard external-drive fastener. The black oxide coating provides a clean appearance appropriate for finished assemblies or equipment with cosmetic requirements. Sold in a package of 50 pieces, this quantity suits shop stock or recurring maintenance needs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNC thread size for compatibility with standard inch-series tapped holes\u003c\/li\u003e\n\u003cli\u003eFully threaded body with 3\/4-inch length under head for maximum thread engagement\u003c\/li\u003e\n\u003cli\u003e3\/32-inch hex drive accepts standard hex key tools\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction provides strength appropriate for mechanical fastening applications\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish improves corrosion resistance and reduces reflectivity compared to bare steel\u003c\/li\u003e\n\u003cli\u003eMeets ANSI B18.3, ANSI B18.8.2, ANSI B2.2, and MS16555 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in any application requiring a 4-40 UNC socket cap screw with a 3\/4-inch length under head and a 3\/32-inch hex drive, conforming to ANSI B18.3 and MS16555 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed with a 3\/32-inch hex key or Allen wrench; use of the correct drive size prevents stripping of the socket recess. Ensure the mating tapped hole is clean and properly formed to 4-40 UNC specification before installation. De-energize any equipment and follow applicable safety lockout procedures before fastening or removing hardware in electrical or mechanical assemblies. Do not over-torque; alloy steel cap screws at this thread size are susceptible to thread stripping if force is applied beyond the fastener rating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.75 inches\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 inches\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\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: MP72026\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696652681522,"sku":"MP72026","price":19.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49e63fc5bd21f6beda16b7e0bf93c231.jpg?v=1788344829","url":"https:\/\/voomisupply.com\/products\/value-collection-mp72026-hex-socket-cap-screw-4-40-unc-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
