It features a 3\/8 inch length under head, full threading along the entire shank, and a 3\/32 inch hex drive. Manufactured from alloy steel with a black oxide finish, this fastener provides corrosion resistance and a low-reflectance appearance suited to assemblies where surface protection and consistent torque performance matter. It meets ASME\/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for demanding mechanical and structural applications. Machinists, maintenance technicians, and precision assembly workers commonly use this fastener type.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in light mechanical assemblies, instrument panels, electronics enclosures, and small machine components where a compact, high-strength fastener is required. The 4-40 UNC thread is a fine-pitch unified coarse thread standard widely used in American manufacturing for small fastener applications. The black oxide coating makes it suitable for applications where a non-reflective finish is preferred or where mild corrosion protection is needed in controlled indoor environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-40 UNC thread form, fully threaded along entire shank length\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch length under head for consistent grip in standard 4-40 tapped holes\u003c\/li\u003e\n  \u003cli\u003e3\/32 inch hex socket drive for use with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction meets ASTM A574 mechanical requirements\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish provides mild corrosion resistance and low-reflectance surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ASME\/ANSI B18.3 and IFI 124 dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock fastener for any application requiring a 4-40 UNC fully threaded hex socket cap screw with a 3\/8 inch length under head.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 3\/32 inch hex key or Allen driver; ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the rated torque for 4-40 alloy steel fasteners as specified in applicable ASME or IFI fastener torque tables. Always inspect threads for damage prior to installation. Power down any electrical or mechanical system before fastener service where energized components are present.\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: 3\/8 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\u003eFull or Partial Threading\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 Coating\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3, ASTM A574, IFI 124\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 015035PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698194055474,"sku":"015035PR","price":8118.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05964fd5a6c0203726ed30880beb98f9.jpg?v=1788359125","url":"https:\/\/voomisupply.com\/products\/value-collection-015035pr-hex-socket-cap-screw-4-40-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
