Built from grade 12.9 alloy steel with a black oxide finish, it delivers high tensile strength and moderate corrosion resistance in a compact, low-profile head. The 90-degree flat head seats cleanly into countersunk holes, and the 10 mm hex socket drive accepts standard hex keys for controlled torque application. At M16x2 thread size with a 40 mm overall length and full threading, this screw is suited for structural and mechanical assemblies where a conventional cap screw head would protrude unacceptably. Machinists, millwrights, and industrial maintenance technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in precision mechanical assemblies, machine frames, fixtures, and industrial equipment where a flush fastener surface is required. The M16x2 thread and grade 12.9 material make it appropriate for high-load, high-stress connections in metal-to-metal joints. The black oxide finish provides a non-reflective surface and light lubricity during installation. It is fully threaded along its 40 mm body length, making it effective in through-hole and blind-hole applications where maximum thread engagement is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 12.9 alloy steel construction for high tensile and proof load ratings\u003c\/li\u003e\n  \u003cli\u003e90-degree flat head profile for flush countersunk installation\u003c\/li\u003e\n  \u003cli\u003e10 mm hex socket drive for positive torque engagement with standard hex keys\u003c\/li\u003e\n  \u003cli\u003eBlack oxide finish for low-reflectance surface and light corrosion protection\u003c\/li\u003e\n  \u003cli\u003eFully threaded body along the entire 40 mm length for maximum thread engagement\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 as a metric countersunk socket cap screw conforming to ISO 10642 and ANSI B1.13M, suitable for standard M16x2 threaded holes in metal assemblies requiring a flush or countersunk fastener seating surface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, millwrights, or maintenance technicians using a 10 mm hex key or socket driver. Ensure the mating countersink angle matches the 90-degree head geometry before installation to achieve full head seating. Verify thread class compatibility with the tapped hole prior to assembly; this screw carries a 4G thread fit class per metric standards. De-energize, lock out, and tag out any machinery before servicing fasteners in live equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M16x2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 40 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: 10 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 33.60 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 8.8000 inches decimal equivalent noted; metric head per ISO 10642\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\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\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\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  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 87212\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51743124488498,"sku":"87212","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e14fa2f3ded20955a633a001935bb0_b919daca-8abe-4064-b1e5-4c7d62bc163a.jpg?v=1788842964","url":"https:\/\/voomisupply.com\/products\/holo-krome-87212-flat-socket-cap-screw-m16x2-40mm","provider":"Voomi Supply","version":"1.0","type":"link"}
