It features an 82-degree flat head driven by a 5\/64-inch hex socket and is fully threaded along its 3\/8-inch overall length. The 5-40 UNC thread with a Class 3A fit provides close tolerances and reliable engagement in precision assemblies. Manufactured from alloy steel with a black oxide finish, the fastener delivers hardness in the 39-44 HRC range for high-strength clamping. This screw is installed by machinists, maintenance technicians, and mechanical assemblers working on light mechanical and instrument-grade assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for low-profile fastening tasks where a standard socket cap head would protrude above the mating surface. The 5-40 thread size and 3\/8-inch length make it appropriate for thin panels, small enclosures, precision instruments, and light-duty mechanical assemblies where head clearance is limited. The black oxide finish provides mild corrosion resistance and reduces light reflection in service environments where appearance and surface contrast matter. Sold individually with a minimum order quantity of 100 pieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head seats flush in standard countersunk holes\u003c\/li\u003e\n  \u003cli\u003e5\/64-inch hex socket drive for precise torque application in tight spaces\u003c\/li\u003e\n  \u003cli\u003eFully threaded 3\/8-inch overall length for maximum thread engagement in thin materials\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 39-44 HRC hardness for high-strength fastening\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectance appearance\u003c\/li\u003e\n  \u003cli\u003eClass 3A thread fit meets ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use fastener for applications requiring a 5-40 UNC fully threaded flat socket cap screw with an 82-degree countersink angle, conforming to ASME B18.3 and ASTM F835 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed with a calibrated 5\/64-inch hex key or hex bit driver. Ensure the mating part features an 82-degree countersunk hole sized for the 0.281-inch head diameter before installation. Do not use an undersized or worn hex key, as this can strip the socket drive. Follow applicable torque guidelines from the fastener standard for the 5-40 thread class and material combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/8 inches (overall)\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: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.281 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.090 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\u003eThread Fit Class\u003c\/strong\u003e: 3A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\u003eHardness\u003c\/strong\u003e: 39-44 HRC\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 B18.3, ASTM F835\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 60014\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51754503733554,"sku":"60014","price":4951.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd58269ddea2b207c790f87115ebc8bf.jpg?v=1788946104","url":"https:\/\/voomisupply.com\/products\/holo-krome-60014-flat-socket-cap-screw-5-40-x-3-8-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
