Manufactured from alloy steel with a black oxide finish, this screw offers good hardness and corrosion resistance in low-moisture environments. The Torx Plus T10 drive reduces cam-out during installation and allows higher torque transfer compared to standard hex socket drives. The 82-degree flat head seats flush with the mating surface. Fully threaded along its 1\/4 inch overall length, the 4-40 UNC thread pattern suits fine-pitch metric and inch-standard assemblies common in electronics, instrumentation, and light mechanical work.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for applications requiring a low-profile fastener in tight assemblies, including electronic enclosures, instrument panels, fixtures, and precision mechanical components. The 4-40 thread size is widely used in small-scale fabrication and OEM assembly environments. Sold individually, with a minimum order quantity of 100 pieces, this part is appropriate for production runs, maintenance kits, or restocking trade fastener inventories.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head provides a flush countersunk seating profile\u003c\/li\u003e\n  \u003cli\u003eTorx Plus T10 drive reduces cam-out and supports higher installation torque\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction for strength in precision fastening applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eFully threaded 4-40 UNC over 1\/4 inch overall length\u003c\/li\u003e\n  \u003cli\u003eMeets ASME\/ANSI B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard inch-series flat socket cap screw compatible with any 4-40 UNC tapped hole or nut requiring an 82-degree countersunk flat head seating geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a Torx Plus T10 driver or bit; do not substitute a standard Torx T10 bit where a Torx Plus drive is specified, as this can damage the drive recess. Verify the mating countersink is machined to an 82-degree included angle before installing. De-energize and discharge any assembly before installing fasteners in electrical or electronic enclosures per applicable NEC guidelines. Do not over-torque alloy steel screws in soft substrate materials such as aluminum or plastic.\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\u003eLength\u003c\/strong\u003e: 1\/4 inches (overall)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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 Standard\u003c\/strong\u003e: ASME\/ANSI B18.3; ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.001 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: 354-5404-01\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714857959730,"sku":"354-5404-01","price":2065.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a803cc54e8d83d993cb452a2f8a36001.jpg?v=1788507085","url":"https:\/\/voomisupply.com\/products\/value-collection-354-5404-01-flat-socket-cap-screw-4-40","provider":"Voomi Supply","version":"1.0","type":"link"}
