Constructed from steel with a black phosphate finish, it resists corrosion and stands up to repeated impact driver use. The non-sparking construction makes it suitable for environments where ignition risk is a concern. Standard length geometry keeps the socket compact for use in confined spaces. This socket is installed by licensed electricians, millwrights, heavy equipment technicians, and industrial maintenance professionals who require reliable torque transfer at high-impact cycles.\u003c\/p\u003e\n\u003cp\u003eThis socket fits 1-inch square drive impact wrenches and is sized for 41mm hex fasteners commonly found on heavy machinery, structural bolting, and industrial equipment assemblies. The 6-point contact pattern distributes torque evenly across fastener flats, reducing the risk of rounding under load. The black phosphate finish provides a low-glare surface and mild corrosion resistance for shop and field use. Standard length suits most open-access fastening tasks without requiring an extension.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch square drive compatible with full-size impact wrenches\u003c\/li\u003e\n  \u003cli\u003e41mm socket size for large hex fasteners on heavy equipment\u003c\/li\u003e\n  \u003cli\u003e6-point hex drive reduces fastener rounding under high torque\u003c\/li\u003e\n  \u003cli\u003eNon-sparking construction rated for use in ignition-sensitive environments\u003c\/li\u003e\n  \u003cli\u003eBlack phosphate finish for corrosion resistance and low glare\u003c\/li\u003e\n  \u003cli\u003eStandard length profile for direct-access fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style impact socket for use with 1-inch drive impact wrenches requiring a 41mm 6-point hex socket.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis socket is installed and used by qualified trades and maintenance technicians operating 1-inch drive impact wrenches. Always ensure the drive tool is powered down or the air supply is disconnected before changing sockets. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Do not use impact sockets with hand-drive ratchets, as impact-rated sockets are not designed for that loading profile.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket Size\u003c\/strong\u003e: 41mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Points\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Style\u003c\/strong\u003e: Hex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Phosphate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNon-Sparking\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsulated\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.78 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111704\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: MILWAUKEE TOOL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-66-6604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51689412985138,"sku":"49-66-6604","price":56.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6806a0ca8d95138e9a81b1812794ebc3.jpg?v=1788259068","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-49-66-6604-impact-socket-1in-drive-41mm","provider":"Voomi Supply","version":"1.0","type":"link"}
