The driver is machined from heat-treated Custom Alloy 76 steel, which controls hardness across the shank and tip for extended service life under repeated impact loading. A dedicated Shock Zone in the shank absorbs peak torque to reduce tip breakage. The hex geometry is tightly toleranced for a snug fit on fastener heads, and a chamfered edge at the tip maximizes screw-head engagement and reduces cam-out. Overall length is 2-9\/16 inches.\u003c\/p\u003e\n\u003cp\u003eThis nut driver is suited for residential and commercial construction, mechanical, and electrical trade work wherever 1\/2-inch fasteners are driven at volume. It is designed specifically for use with impact drivers and drill drivers, making it a standard addition to an electrician, HVAC technician, or general contractor tool kit. The color-coded band on the shank allows fast size identification when multiple nut drivers are staged on a belt or in a pouch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeat-treated Custom Alloy 76 steel construction for controlled hardness and extended bit life\u003c\/li\u003e\n  \u003cli\u003eShock Zone geometry absorbs peak impact torque and reduces tip breakage\u003c\/li\u003e\n  \u003cli\u003eDurable magnet holds fasteners securely during single-handed positioning and set-up\u003c\/li\u003e\n  \u003cli\u003eChamfered tip edge maximizes screw-head engagement and reduces stripping\u003c\/li\u003e\n  \u003cli\u003eImproved hex geometry provides tight fit on 1\/2-inch fastener heads\u003c\/li\u003e\n  \u003cli\u003eColor-coded band for fast visual size identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard impact drivers and drill drivers accepting 1\/4-inch hex shank accessories.

Seat the 1\/4-inch hex shank fully into the tool chuck before driving to ensure secure engagement. This driver is rated for impact driver use; avoid applying lateral force or using it as a pry point, as this can damage the shank. Follow applicable jobsite safety codes when operating rotary tools overhead or in confined spaces.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-9\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 1\/4-inch hex, impact-ready\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Heat-treated Custom Alloy 76 steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 045242266623\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 49-66-4537\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51383999562034,"sku":"49-66-4537","price":35.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312671106.png?v=1782614656","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-66-4537-magnetic-nut-driver-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
