Milwaukee 49-66-4703 – Frequently Asked Questions

1) What hex sizes do the Milwaukee SHOCKWAVE magnetic nut drivers come in?
Three hex sizes across six part numbers: 1/4 inch (49-66-4712), 5/16 inch (49-66-4703, 49-66-4713, 49-66-4733) and 3/8 inch (49-66-4705, 49-66-4735). 5/16 and 3/8 are the two common sizes for self-drilling hex-head sheet metal and strut screws; 1/4 inch covers smaller hex-head fasteners.
2) What is the difference between the 1 inch insert nut drivers and the 1-7/8 inch ones?
Length and how they mount. The 1 inch insert versions (1/4 inch 49-66-4712, 5/16 inch 49-66-4713) are designed to drop into a bit holder or magnetic extension, not into the chuck on their own. The 1-7/8 inch drivers (49-66-4703 in 5/16, 49-66-4705 in 3/8) go straight into an impact driver. If you are already running a quick-change bit holder, order the inserts; if not, take the 1-7/8 inch.
3) Which length do I need to reach hex screws down inside strut or a deep channel?
Go with the 2-9/16 inch drivers: 49-66-4733 in 5/16 inch or 49-66-4735 in 3/8 inch. That extra length past the 1-7/8 inch version is what clears a raised flange or gets the socket down over a screw sitting recessed in strut or a deep pan. For flat-surface work the 1-7/8 inch drivers keep the tool shorter and steadier.
4) Can I use these nut drivers in an impact driver, or only a drill?
Both. The SHOCKWAVE Impact Duty nut drivers are built for impact drivers and drill drivers, and the CUSTOM ALLOY76 steel is what lets them take heavy-duty impact work rather than shearing off. They are not hand-tool-only sockets.
5) Will the magnet hold a self-drilling screw well enough to start it one-handed overhead?
That is the point of the magnetic version. The magnet holds the screw in the socket during set-up so you can start a hex-head screw overhead or in a ladder position without a second hand, and Milwaukee's Impact Duty magnet is built so it does not work loose from repeated hammering the way a pressed-in magnet can.
6) Why do my nut drivers keep rounding out screw heads, and will these be different?
Rounding usually comes from a loose socket fit letting the driver ride up off the hex. These SHOCKWAVE drivers use an improved hex geometry for a tighter fit and reduced stripping, plus a chamfered edge that pulls the screw head fully into the socket instead of engaging on the corners only.
