CTA Tools 2049 Square Head Drain Plug Sockets, 2 Piece Set

The 10mm square socket helped me drain and refill the transmission, transfer case, and differentials in my 1993 Suzuki Sidekick. Much better fitment and engagement than a 3/8" ratchet, and I can get proper torque on the drain/fill plugs. I picked up the 8mm as well in the event that I need it for future projects. Fast shipping, great price, and solid build quality. These are hard to find locally, so grab them here before your next project!

Really helpful when I need to change the gear oil in my transfer case. While you can get away with a 3/8 drive those aren’t perfectly squared and can strip the drain plug. Highly recommend these!

I wanted to completely drain and flush the coolant on my Jeep 4.0 block. I needed the 8 mm to remove the block plug. functioned perfectly and made for quick and easy removal of the old plug. With both sockets in one package, it made it a great value for the money!

Needed one of the provided drain plugs in order to drain the transfer-case fluid out of my Nissan Versa manual transmission. Nissan decided to use a female square head drain plug probably to keep people from messing with the transmission. A 3/8" ratchet or a 1/2" ratchet will not work with these drain plugs. These drain plug sockets were cheap and did their job. Feel solid. Hopefully will never have to test their toughness in the future.

I don't like that the sockets don't have any kind of marking identifying the size, but that being said, once I got under the car it made the job easy. I spent two days looking for this tool at my local auto parts stores. It was an easy tool to find for some reason. Great price and quick delivery with Prime. Thank you, Amazon.

This fit a 2007 5.7 Tundra very snug. Good value for two sockets.

Needed to drain my transmission oil in a 05 susuki forenza 4dr S and this adapter came in handy. Great quality and overall use. Happy with buying it.

So I got these and a t-handle to build a makeshift one-size-fits-all lathe chuck wrench. That would have worked great if I didn't need 11mm instead of 10mm, but whatever. 10mm will be useful in the future. I really just needed the 8mm because 9x20 lathe wrenches are child-sized and seemingly impossible to upgrade otherwise. In other news, these things actually seem to be made of some decent hard metal. The keyholes on a lathe chuck are made of some tough stuff. Rounded off my previous attempt to make one of these right quick. In this case, the 10mm held up to being used in an 11mm hole without any scuffs, although I gave up on that idea quite quickly. The 8mm decidedly made my purchase worth it. Plenty of torquing on the little fellow with no problem. If I had to complain about anything, I'd say they don't fit very tight on the wrench. I'd prefer if these were fashioned for an impact wrench as those sit super tight, but that might be asking too much.

Buen producto cumple con su función

Worked perfectly, removed the stuck rear differential drain plug on my grand vitara.

Good value for the price

Son de buen material. Los use para una Renault Duster y el tapón del carter demasiado apretado, lo aflojó sin problema.

It worked to get the fill plug on my transfer case out.
