It features an M3x0.5 thread and a 6 mm length under head, driven by a 2 mm hex socket. The button head profile provides a low-profile, rounded appearance suited for assemblies where clearance is tight or aesthetics matter. At a material grade of 12.9 and a hardness rating of 38-43 HRC, this fastener delivers high tensile strength for demanding mechanical and structural applications. It conforms to ANSI\/ASME B18.3.4M and ISO 7380 standards, ensuring dimensional consistency across precision assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is commonly used in machine assembly, fixture building, tooling, robotics, and light structural applications where a recessed hex drive and low-profile head are required. The black oxide coating provides mild corrosion resistance and reduces light reflection, making it a practical choice for both industrial equipment and precision instrument housings. It is fully threaded and suitable for use in metric-threaded holes or with a matching metric nut. This item is sold individually but carries a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM3x0.5 metric thread with right-hand thread direction and 4G\/6G fit class for reliable engagement\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction at material grade 12.9 for high tensile and proof load strength\u003c\/li\u003e\n  \u003cli\u003e38-43 HRC hardness rating supports use in high-stress fastening applications\u003c\/li\u003e\n  \u003cli\u003e2 mm hex socket drive with low-profile button head for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003eBlack oxide coating reduces surface corrosion and minimizes reflectivity\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI\/ASME B18.3.4M and ISO 7380 standards for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard metric replacement or new-installation fastener for M3x0.5 threaded assemblies conforming to ISO 7380 and ANSI\/ASME B18.3.4M specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed using a 2 mm hex key or hex socket driver. Verify that the mating threaded hole or nut is M3x0.5 metric before installation to ensure proper thread engagement. Always check that the fastener grade is appropriate for the joint load before torquing. Black oxide fasteners should not be used as a substitute for fully corrosion-resistant hardware in wet or outdoor environments without additional protective treatment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3x0.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 6 mm\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 mm\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: 38-43 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 B18.3.4M \/ ISO 7380\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 535004PR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51693921763634,"sku":"535004PR","price":1396.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d4e30d1b0aa9d7330d11e10487614be6.jpg?v=1788319075","url":"https:\/\/voomisupply.com\/products\/value-collection-535004pr-m3x0-5-button-socket-cap-screw","provider":"Voomi Supply","version":"1.0","type":"link"}
