Sized M5x0.80 with a 16mm length under the head, it is fully threaded and manufactured from Grade 12.9 alloy steel  -  the highest standard strength grade for metric fasteners. The black oxide finish provides mild corrosion resistance and a clean appearance. The hex socket drive measures 3.00mm and accepts a standard hex key. This fastener is installed by mechanical technicians, millwrights, and field service technicians across industrial and commercial assembly applications.\u003c\/p\u003e\u003cp\u003eThis screw is suited for applications where a flush or low-profile head profile is needed and bolt spacing is tight. Common use cases include machinery guards, brackets, enclosures, and precision mechanical assemblies. The M5x0.80 thread size and metric standard make it appropriate for equipment manufactured to metric specifications. Thread fit classes 4G and 6G allow compatibility with a range of tapped metric holes. Compliance with ANSI\/ASME B18.3 and ASTM F835 makes it appropriate for use in engineered assemblies requiring documented fastener standards.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 12.9 alloy steel construction for high tensile and shear strength\u003c\/li\u003e\n\u003cli\u003eBlack oxide finish for mild corrosion resistance and reduced light reflection\u003c\/li\u003e\n\u003cli\u003eButton head profile provides a low-profile seating surface\u003c\/li\u003e\n\u003cli\u003e3.00mm hex socket drive accepts standard metric hex keys\u003c\/li\u003e\n\u003cli\u003eFully threaded along the 16mm length under head\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 for use in metric-tapped holes sized M5x0.80 with thread fit classes 4G or 6G, per ANSI\/ASME B18.3 and ASTM F835 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a 3.00mm hex key or hex socket bit driver. Ensure the receiving tapped hole is clean and free of debris before threading. Torque to the value specified by the engineering documentation for the assembly  -  do not rely on generic torque figures for Grade 12.9 fasteners without confirming application requirements. Hardness is rated at 38 HRC; avoid use with softer mating materials that may be damaged under full clamp load.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5x0.80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 16.00mm\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: 3.00mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 9.50mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 2.75mm\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\u003eThread Engagement\u003c\/strong\u003e: Fully Threaded\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 86019\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51740036596018,"sku":"86019","price":4395.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1172579a6e9f74d03f5f092e910be8d4.jpg?v=1788821689","url":"https:\/\/voomisupply.com\/products\/holo-krome-86019-m5x0-80-button-cap-screw-grade-12-9","provider":"Voomi Supply","version":"1.0","type":"link"}
