      Handy for use where you need a larger socket but a ½” ratchet doesn’t fit
      Handy to adapt ⅜” drive tools to drive ½” drive sockets and extensions. Seems well made. It is made in China which is a bit of a disappointment. It does have a lifetime warranty. The adapter stays on a ratchet with a quick release ball retainer well. Half inch sockets stay on the half inch end well too. Removal from a ratchet and removing from a socket isn’t unnecessarily difficult either.

      Quality Socket Adapter
      The Milwaukee 3/8 inch drive 3/8 inch F X 1/2 inch M Adapter is a quality tool with a great chrome finish and fits just tight enough to not slip off the socket or wrench. The flat sides fit a 7/16 inch open end wrench which could come in handy at times. When working on machinery or cars there is always that one nut or bolt that is so hard to get too. The more options you have for different sizes if sockets or wrenches the better. This 3/8 drive adapter is just another tool that gives you more options. This quality Milwaukee tool has a lifetime guarantee.

      You can use a ratchet or a wrench
      Anyone who has worked on a modern can has felt the frustration of limited access to fasteners. With this socket adapter you get another option to remove hard to reach bolts, nuts, and screws. It works equally well with a standard ratchet or a wrench. You can slip the adapter on the appropriate socket into a tight spot and loosen a fitting with a wrench in a spot that would end up getting a ratchet stuck. Having more options earned this a place in my truck tool box.

      It won't roll away and you can use a wrench to turn it.
      Like many I have a variety of tool from years of working on my projects and employment. I wasn't sure I needed a new socket adapter but I liked the flat sides. One of the first things I did was use a wrench to turn a socket in a place I couldn't fit a ratchet. It worked like a charm and I didn't get stuck causing me to try and run the bolt back in to get my ratchet head free. As a plus it won't roll away if you set it down on the ground next to you while working. It works fine as an adapter but having the option to put a wrench on it makes it more useful than my other options.

      trusted brand
      Milwaukee 1/4" drive 1/4"F x 3/8"M adapter has just been added to my collection of wonderful Milwaukee tools and accessories. I have found that having the right tool for the job is everything. Milwaukee is a trusted brand that has been around for years and is priced right. I rarely have to replace an item (misplaced, lost, or let someone borrow), usually only add to what I already have. I got to use the adapter to help assemble an outdoor chair over the weekend, so you don't have to be a mechanic to use it.

      Nice socket adapter
      This is a nice socket adapter. The build quality is excellent. The chrome finish is nice all around. The adapter is meant for 1/4" socket wrenches and 3/8" sockets. It fits 1/4" socket wrenches and 3/8" sockets perfectly. For the most part, I wouldn't use this with larger sockets and stick to using it with smaller 10 mm to 14 mm sockets where I don't need a lot of torque to remove or install nuts and screws. My expectations have been exceeded.

      Nice socket adapter
      This is a nice socket adapter. For use with a 3/8" socket wrench and 1/2" sockets, it fits 3/8" socket wrenches and 1/2" sockets perfectly. The build quality is excellent. There is a spring-loaded ball bearing to lock onto sockets. The chrome finish is nice. To be used when you have a 3/8" socket wrench and want to use 1/2" sockets. My expectations have been exceeded.

      For when you need to size down 1/2 F to 3/8 M
      There are always times when you need an adapter for your driver set. I have several other Milwaukee tools and they last. This is just an adapter, so I do not expect anything less. I have already had the opportunity to use the adapter while working on my vehicle. It is well made and I trust Milwaukee. It has a lifetime guarantee so nothing to worry there.

      Quick and easy to adapt!
      Sometimes it is easier and cheaper to just get yourself an adapter than to buy a whole new tool, and that is exactly where this little guy comes in. For the most part, many of my tools are 3/8” but occasionally I need to use something bigger. In my case I needed an adapter to fit my socket onto my 1/2” breaker bar and this adapter did the trick with zero issues. The inner locking tabs hold well and haven’t had any issues with the adapter coming off unexpectedly. One of my favorite features is that the adapter has four flat sides, preventing it from rolling away anytime you set it down. It also features clear markings etched onto the adapter which makes it significantly easier and quicker to identify in the toolbox.
