Sized at M8x1.25 with a 12mm length under head, this screw is fully threaded and features a hex socket drive requiring a 5mm hex key. It is manufactured from grade 12.9 alloy steel, making it one of the highest-strength classifications in the metric fastener system, with a hardness rating of 38 HRC. The black oxide finish provides mild corrosion resistance and a low-profile appearance. Machinists, millwrights, and maintenance technicians commonly install this fastener in tight-clearance applications where a low-profile button head is required.\u003c\/p\u003e\n\u003cp\u003eThis button socket cap screw is suited for use in machinery frames, fixtures, jigs, and equipment housings where high clamp load and a flush or near-flush head profile are needed. The metric M8x1.25 thread pitch and 4G\/6G thread fit class make it compatible with standard metric threaded assemblies across manufacturing, automation, and industrial maintenance environments. It meets ANSI\/ASME B18.3 and ASTM F835 fastener standards, making it appropriate for applications that require documented compliance with recognized dimensional and mechanical specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction with 38 HRC hardness for maximum tensile strength\u003c\/li\u003e\n  \u003cli\u003eButton head profile provides low clearance height of 4.4mm for tight-space installations\u003c\/li\u003e\n  \u003cli\u003e14.0mm head diameter distributes clamping load over a wider bearing surface\u003c\/li\u003e\n  \u003cli\u003e5mm hex socket drive for precise torque application with standard hex keys or Allen drivers\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/ASME B18.3 and ASTM F835 standards for dimensional and mechanical compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard metric M8x1.25 threaded assemblies with 4G or 6G thread fit class.

Always ensure the mating threaded hole is clean and free of debris before installation. Power down and de-energize any equipment before accessing fastened assemblies in live machinery. Do not substitute a lower-grade fastener in applications that specify grade 12.9 hardware, as mechanical failure may result.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M8x1.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12mm\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: 5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 14.0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 4.4mm\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  \u003cli\u003e\n\u003cstrong\u003eThread Engagement\u003c\/strong\u003e: Fully Threaded\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: 86041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51741139075378,"sku":"86041","price":7754.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7c3f3c26cc1d410b721db35a8d7b90cc.jpg?v=1788829560","url":"https:\/\/voomisupply.com\/products\/holo-krome-86041-button-socket-cap-screw-m8x1-25-12mm","provider":"Voomi Supply","version":"1.0","type":"link"}
