Manufactured from Grade 10.9 alloy steel, this fully threaded fastener delivers high tensile strength and reliable clamping force in tight-clearance installations. The blue phosphate finish provides a measure of corrosion resistance and surface protection. The low-profile button head and 2.5mm hex socket drive make this screw well-suited for applications where standard cap screw heads would interfere with mating components or adjacent hardware.\u003c\/p\u003e\n\u003cp\u003eThis screw is used in general mechanical, industrial, and equipment assembly work where metric fasteners are specified. The button head profile keeps the fastener low to the surface, making it a common choice in panel mounting, enclosure assembly, and machinery fabrication. It conforms to ISO 7380 fastener standards and uses a metric thread standard, making it compatible with metric-threaded hardware throughout. Minimum order quantity is 10 pieces per order. Typically installed by maintenance technicians, mechanical assemblers, and trade professionals working with metric-spec equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM4x0.70 fully threaded metric thread for consistent engagement\u003c\/li\u003e\n  \u003cli\u003eGrade 10.9 alloy steel construction for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eLow-profile button head for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003e2.5mm hex socket drive for precise torque application\u003c\/li\u003e\n  \u003cli\u003eBlue phosphate finish for surface protection and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 7380 fastener standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ISO 7380-compliant metric button socket cap screw suitable for use in standard M4x0.70 threaded assemblies across mechanical and industrial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a 2.5mm hex socket driver or hex key. Ensure the mating threaded hole is clean and free of debris before installation. Do not overtighten, as high-strength alloy screws can strip smaller metric threads if torque is not controlled. Power down or de-energize any equipment before servicing fasteners on live assemblies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M4x0.70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 25mm\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: 2.50mm\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: ISO 7380\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: 10.9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Blue Phosphate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Engagement\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: METRIC BLUE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UST187481\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"METRIC BLUE","offers":[{"title":"Default Title","offer_id":67918803108146,"sku":"UST187481","price":1331.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b0a39b96b8740bfeca16561f203f806_5c5e9b4e-f9c3-48b6-8163-ff8cd3fdc31c.jpg?v=1791273203","url":"https:\/\/voomisupply.com\/products\/metric-blue-ust187481-m4x0-70-button-cap-screw-25mm","provider":"Voomi Supply","version":"1.0","type":"link"}
