Manufactured from alloy steel with a black oxide finish, this screw features an 82-degree flat head and a 5\/64-inch hex socket drive. It is fully threaded along its 1\/4-inch overall length and carries a 5-40 UNC thread form with a Class 3A thread fit. Hardness is rated at 39-44 HRC, making it suitable for demanding mechanical assemblies where a countersunk seating profile is required. Machinists, tool and die technicians, and precision assembly professionals are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in precision mechanical assemblies, machine tool fixtures, jigs, and equipment enclosures where the fastener head must sit flush with or below the mating surface. The 82-degree flat head geometry conforms to ASME B18.3 and ASTM F835 standards, making it a drop-in fit for standard countersunk hole patterns in inch-series applications. Its compact 5-40 thread size suits miniature and light-duty assemblies found in instrumentation, electronics enclosures, and small mechanical devices.\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 per ASME B18.3\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 provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n  \u003cli\u003e5\/64-inch hex socket drive for precision torque application in tight spaces\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/4-inch overall length maximizes thread engagement\u003c\/li\u003e\n  \u003cli\u003eClass 3A thread fit per UNC standard ensures close-tolerance mating\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 inch-series countersunk fastener applications conforming to ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires a 5\/64-inch hex key or socket driver. The mating workpiece must have an 82-degree countersunk hole sized to accept the 0.281-inch head diameter to achieve a proper flush seat. Power down and de-energize any equipment before fastener installation or removal when working on electrical or mechanical assemblies. Avoid over-torquing, as alloy steel screws at this thread size are subject to shear if torque limits are exceeded.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.25 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\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: 60012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51737554878770,"sku":"60012","price":4184.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e8d897ab5743d77d0d1fc44e13a3579b.jpg?v=1788790311","url":"https:\/\/voomisupply.com\/products\/holo-krome-60012-flat-socket-cap-screw-5-40-x-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
