It features a 90-degree flat head driven by an 8 mm hex socket and is fully threaded along its 30 mm overall length. The screw is manufactured from 12.9 grade alloy steel, placing it among the highest strength class available for metric fasteners. A black oxide finish provides mild corrosion resistance and reduces surface reflectivity. Thread size is M12x1.75 with a 4G thread fit class, conforming to ANSI B1.13M and ISO 10642 standards. Licensed trades and industrial maintenance technicians reach for this fastener when load-bearing flush mounting is required.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for mechanical assemblies, machine frames, tooling fixtures, and structural joints where a protruding head is not acceptable. The fully threaded shank allows engagement throughout the entire fastener length, making it effective in thinner material applications and blind-hole configurations. Its high-strength 12.9 rating makes it appropriate for high-stress joints in manufacturing equipment, heavy machinery, and precision assemblies where standard-grade fasteners would be insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree flat head profile for countersunk, flush-mount installations\u003c\/li\u003e\n  \u003cli\u003e12.9 alloy steel material grade for high-strength fastening applications\u003c\/li\u003e\n  \u003cli\u003eFully threaded along entire 30 mm length for maximum thread engagement\u003c\/li\u003e\n  \u003cli\u003e8 mm hex socket drive for reliable torque transmission\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for mild corrosion resistance and low-reflectivity surface\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI B1.13M and ISO 10642 fastener standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in metric threaded applications requiring an M12x1.75 countersunk socket cap screw conforming to ISO 10642 and ANSI B1.13M standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified mechanic or maintenance technician using a calibrated 8 mm hex key or socket driver. Ensure the receiving hole is properly countersunk to a 90-degree angle to achieve full head seating. De-energize and lock out any equipment before fastener removal or installation on live machinery. Do not substitute a lower-grade fastener in joints engineered for 12.9 class hardware.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M12x1.75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 30 mm overall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\u003c\/strong\u003e: 90-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: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 26.88 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7.44 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: 4G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Metric\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\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ANSI B1.13M, ISO 10642\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Metric\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: 87188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51739596816690,"sku":"87188","price":1199.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a41c1458faab566c72372eba8ce5f095.jpg?v=1788816740","url":"https:\/\/voomisupply.com\/products\/holo-krome-87188-flat-socket-cap-screw-m12x1-75-12-9","provider":"Voomi Supply","version":"1.0","type":"link"}
