This fastener is fully threaded along its entire shank length and driven with a hex (Allen) key. It is designed for precision fastening applications where corrosion resistance and dimensional consistency are critical. The Grade A4 stainless steel construction meets ISO 3506-1 and ISO 4762 standards, making it suitable for demanding environments including wet, marine, and chemical-exposure conditions. Machinists, millwrights, and field technicians install this screw type across a wide range of mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis screw is suited for light-duty to medium-duty fastening in equipment panels, instrumentation housings, machinery guards, and fabricated assemblies where metric fasteners are specified. The M3 thread size is commonly found in compact mechanical and electrical enclosures, HVAC control panels, and precision equipment. The uncoated stainless finish eliminates the risk of coating delamination in high-humidity or corrosive service environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade A4 austenitic stainless steel construction for superior corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFully threaded shank provides maximum thread engagement along the full 12 mm under-head length\u003c\/li\u003e\n  \u003cli\u003eHex socket drive allows torque application in tight clearance areas with a standard Allen key\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating layer to crack, peel, or add dimensional variation\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 3506-1 and ISO 4762 fastener standards\u003c\/li\u003e\n  \u003cli\u003eM3 x 0.50 metric thread form for use wherever metric specifications are required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard ISO 4762 metric hex socket cap screw, suitable for any M3 x 0.50 threaded application requiring a fully threaded, stainless steel fastener.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstall using a correctly sized hex key or Allen driver to avoid rounding the socket drive. Ensure mating threads are clean and free of debris before installation. When installing stainless fasteners into stainless threaded holes, apply an appropriate anti-seize compound to reduce the risk of galling. Power down or de-energize any equipment before accessing internal fasteners on electrical or HVAC enclosures.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M3 x 0.50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreading\u003c\/strong\u003e: Fully Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Type\u003c\/strong\u003e: Hex Socket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel, Austenitic Grade A4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFastener Standard\u003c\/strong\u003e: ISO 3506-1, ISO 4762\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HOLO-KROME\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 77016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HOLO-KROME","offers":[{"title":"Default Title","offer_id":51729637015858,"sku":"77016","price":1488.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3b703018f916ffb6bc2d7317e554fe89_03ff1658-c7ac-451e-8638-3d7d7e0cdc0e.jpg?v=1788707034","url":"https:\/\/voomisupply.com\/products\/holo-krome-77016-m3x0-50-hex-socket-cap-screw-stainless","provider":"Voomi Supply","version":"1.0","type":"link"}
