It features an 82-degree flat head driven by a 5\/16-inch hex socket and is fully threaded along its 2-inch overall length. The 1\/2-20 UNF thread form and Thread Fit Class 3A provide a precise, close-tolerance fit suited to demanding mechanical assemblies. Manufactured from alloy steel with a black oxide finish, the fastener meets ASME B18.3 and ASTM F835 standards. Hardness is rated at 39-44 HRC. Machinists, millwrights, and maintenance technicians install this screw where a standard hex head would protrude above a mating surface.\u003c\/p\u003e\u003cp\u003eThis screw is appropriate for use in precision mechanical assemblies, tooling fixtures, machine frames, and industrial equipment where a low-profile countersunk fastener is required. The 1\/2-20 fine thread pitch offers good resistance to vibration loosening compared to coarse-thread equivalents. The black oxide finish provides mild corrosion resistance and reduces light reflection in service environments where that is a concern. It is suitable for both production assembly and field repair applications across general metalworking and industrial maintenance trades.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e82-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for standard Allen wrench or hex bit\u003c\/li\u003e\n\u003cli\u003eFully threaded 2-inch overall length with 1\/2-20 UNF fine thread\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction, hardness 39-44 HRC\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and low reflectivity\u003c\/li\u003e\n\u003cli\u003eMeets ASME B18.3 and ASTM F835 fastener standards, Thread Fit Class 3A\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-supply flat socket cap screw for any assembly specifying a 1\/2-20 UNF x 2-inch fully threaded, 82-degree flat head hex socket fastener per ASME B18.3.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist, millwright, or mechanical technician familiar with countersunk fastener applications. Ensure the mating countersink is machined to an 82-degree included angle to match the head geometry before driving the screw. Use a properly sized 5\/16-inch hex key or socket bit to avoid rounding the drive recess. De-energize and lock out any equipment before servicing fasteners on moving or powered assemblies.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2 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\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.251 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 Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 3A\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\u003eFastener Standard\u003c\/strong\u003e: ASME B18.3, ASTM F835\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 61060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51741057220914,"sku":"61060","price":1475.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_1b0b9605-7e2f-4138-80ee-1611461b2a34.jpg?v=1788829127","url":"https:\/\/voomisupply.com\/products\/holo-krome-61060-flat-socket-cap-screw-1-2-20-x-2-in-alloy-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
