Machined from alloy steel with a black oxide finish, this screw delivers reliable corrosion resistance and surface hardness in a compact form factor. The 82-degree flat head seats flush with the mating surface, and the Torx Plus T10 drive provides high torque transfer with reduced cam-out compared to standard hex socket drives. At 3\/8 inches overall length and fully threaded, this fastener suits tight-clearance assemblies where full thread engagement is required. Meets ASME\/ANSI B18.3 and ASTM F835 standards. Sold in multiples of 100.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in precision mechanical assemblies, electronic enclosures, fixtures, and light structural applications where a flush fastener surface is necessary. The 4-40 thread size is common in instrument-grade and light-duty assemblies across industrial, commercial, and electronics fabrication environments. The black oxide finish is appropriate for indoor or low-moisture applications. Installation is performed by machinists, fabricators, and maintenance technicians using a Torx Plus T10 driver or bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush with countersunk mating surfaces\u003c\/li\u003e\n  \u003cli\u003eTorx Plus T10 drive reduces cam-out and allows higher torque transfer\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-inch overall length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with black oxide finish for surface hardness and mild corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n  \u003cli\u003e4-40 UNC thread — common in instrument and light-duty mechanical assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard-stock flat socket cap screw for any assembly specifying a 4-40 UNC, 3\/8-inch overall length, 82-degree flat head fastener per ASME\/ANSI B18.3 or ASTM F835.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a Torx Plus T10 driver or power bit. The mating material must be countersunk to an 82-degree angle to achieve a proper flush seat. Ensure the tapped hole threads are clean and free of debris before driving the fastener. Do not exceed the rated torque for 4-40 alloy steel fasteners as specified by the assembly drawing or applicable engineering standard.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/8 inches (Overall Length)\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\u003eHead Type\u003c\/strong\u003e: 82 Degree Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Torx Plus\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorx Size\u003c\/strong\u003e: T10\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\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ASME\/ANSI B18.3; ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 354-5406-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51711555404082,"sku":"354-5406-01","price":2146.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b95d6f5725870bc43c7398cd96f30ae1.jpg?v=1788476916","url":"https:\/\/voomisupply.com\/products\/value-collection-354-5406-01-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
