It features an 82-degree flat head with a 5\/32-inch hex socket drive and a 1\/4-20 UNC fully threaded shank measuring 5\/8 inches in overall length. Manufactured from alloy steel with a black oxide finish, it meets ASME B18.3 and ASTM F835 standards and carries a hardness rating of 39 to 44 HRC. Machinists, millwrights, and maintenance technicians working in industrial and commercial settings regularly specify this fastener where a low-profile head is required.\u003c\/p\u003e\n\u003cp\u003eThis flat socket cap screw is suited for metal fabrication, machine building, tooling plates, and equipment maintenance where a countersunk profile keeps the fastener surface flush with or below the mating material. The 1\/4-20 thread size and fully threaded shank make it compatible with a wide range of standard tapped holes in steel, aluminum, and similar structural materials. The black oxide finish provides moderate corrosion resistance and reduces light reflection, which is useful in precision or optical setups. Thread Fit Class 3A ensures close tolerances and reliable thread engagement in production applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e82-degree flat head profile for flush or countersunk installations\u003c\/li\u003e\n  \u003cli\u003e5\/32-inch hex socket drive for use with standard Allen keys or hex bit drivers\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction with 39 to 44 HRC hardness for high-strength applications\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for moderate corrosion resistance and low-glare surface\u003c\/li\u003e\n  \u003cli\u003eFully threaded 1\/4-20 UNC shank with Thread Fit Class 3A tolerances\u003c\/li\u003e\n  \u003cli\u003eMeets 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 a standard-inch replacement flat socket cap screw for 1\/4-20 UNC tapped holes requiring an 82-degree countersunk head per ASME B18.3 and ASTM F835.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists, millwrights, or maintenance technicians using a 5\/32-inch hex key or Allen driver. Ensure the mating countersink is machined to 82 degrees for proper head seating before installation. De-energize, depressurize, or otherwise isolate the equipment before fastener replacement or removal. Do not exceed the torque capacity of the fastener by using extensions or cheater bars on the hex driver.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5\/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\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.531 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.161 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\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 to 44 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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\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: 60060\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51727816884530,"sku":"60060","price":4992.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd6ff433a0b13caf4540aa1ecd94ace7.jpg?v=1788682926","url":"https:\/\/voomisupply.com\/products\/holo-krome-60060-flat-socket-cap-screw-1-4-20-x-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
