Made from heat-treated Custom Alloy 76 steel, the bit is engineered to maintain controlled hardness through repeated high-torque cycles, extending service life in demanding applications. The integrated SHOCK ZONE geometry absorbs peak torque at the shank to reduce breakage under impact load. A precision-grade magnet secures fastener heads during positioning and drive, keeping screws seated through the full application cycle.\u003c\/p\u003e\u003cp\u003eThis nut driver is suited for residential and commercial construction, mechanical assembly, and electrical work where 5\/16 inch hex fasteners are standard. It is designed to seat and drive sheet metal screws, hex head fasteners, and similar hardware in wood, metal, and composite materials. The color-coded band on the shank allows quick size identification when working from a pouch or open tray alongside other driver sizes. Compatible with any 1\/4 inch hex quick-change chuck on standard impact drivers and drill drivers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeat-treated Custom Alloy 76 steel controls hardness for extended bit life under impact load\u003c\/li\u003e\n\u003cli\u003eSHOCK ZONE geometry at the shank absorbs peak torque and reduces breakage\u003c\/li\u003e\n\u003cli\u003eImpact Duty magnet resists loosening over repeated heavy-duty cycles\u003c\/li\u003e\n\u003cli\u003eChamfered tip edge maximizes screw-head engagement and reduces cam-out\u003c\/li\u003e\n\u003cli\u003eImproved hex geometry provides tighter fit and reduced stripping\u003c\/li\u003e\n\u003cli\u003eColor-coded band for fast size identification in multi-bit setups\u003c\/li\u003e\n\u003cli\u003eCompatible with both impact drivers and drill drivers via 1\/4 inch hex chuck\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with impact drivers and drill drivers equipped with a standard 1\/4 inch hex quick-change chuck.

Ensure the driver is powered off or the battery is disconnected before inserting or removing the bit from the chuck. Do not use with a rotary hammer in impact mode. Inspect the magnet and tip geometry before each use and replace the bit if the tip shows visible rounding or the hex shank is damaged.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Size\u003c\/strong\u003e: 5\/16 inches hex\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Width\u003c\/strong\u003e: 0.49 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: 0045242213894\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 49-66-4703\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51343737618738,"sku":"49-66-4703","price":36.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310513443.jpg?v=1782024155","url":"https:\/\/voomisupply.com\/products\/milwaukee-49-66-4703-shockwave-magnetic-nut-driver-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
