It features an M12x1.75 thread size, 20mm length under head, and is fully threaded with a right-hand thread direction. The 8mm hex socket drive allows for installation with a standard hex key or socket driver. Built from Grade 12.9 alloy steel with a black oxide finish, this fastener delivers high tensile strength combined with moderate corrosion resistance. Licensed trade professionals and industrial maintenance technicians specify Grade 12.9 fasteners where standard hardware-grade bolts are insufficient.\u003c\/p\u003e\u003cp\u003eThe 86063 is suited for mechanical assemblies, machine frames, tooling fixtures, and equipment where a flush or low-profile fastener head is required. The button head design distributes clamping load over a wider bearing surface than a standard socket head cap screw, making it appropriate for use in sheet metal, plastic housings, and thin-flange applications. The black oxide finish provides a clean appearance and light surface protection in dry or mildly humid environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile and proof load ratings\u003c\/li\u003e\n\u003cli\u003eButton head profile minimizes protrusion and distributes clamping load over a larger area\u003c\/li\u003e\n\u003cli\u003e8mm hex socket drive compatible with standard hex keys and socket drivers\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish provides mild corrosion resistance and reduces light reflection\u003c\/li\u003e\n\u003cli\u003eFully threaded along the 20mm shank length for maximum thread engagement in shallow bosses\u003c\/li\u003e\n\u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and general-use replacement or spec fastener for metric M12x1.75 button socket cap screw applications conforming to ANSI\/ASME B18.3 and ASTM F835 standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified mechanic or industrial maintenance technician using a calibrated torque wrench and the appropriate 8mm hex key or bit socket. Always verify mating thread class compatibility before assembly, as this fastener carries a 4G and 6G thread fit class designation. De-energize and lock out any equipment before fastener replacement on machinery. Do not exceed the rated torque for Grade 12.9 M12 fasteners as published by the applicable engineering standard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 20mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: Button\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: 8mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 21.0mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 6.6mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 12.9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 38 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Fit Class\u003c\/strong\u003e: 4G \/ 6G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI\/ASME B18.3 \/ ASTM F835\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: 86063\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743307268402,"sku":"86063","price":1799.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/539a77c2c5646f81966c5116e206d009_2e8da182-08bb-4407-890f-e0f3c08c2d7a.jpg?v=1788845405","url":"https:\/\/voomisupply.com\/products\/holo-krome-86063-button-socket-cap-screw-m12x1-75-20mm","provider":"Voomi Supply","version":"1.0","type":"link"}
