CARBYNE 8-Piece XZN Triple Square Stubby Low Profile Bit Socket Set, 4mm to 16mm, 12 Point Spline, S2 Steel, Dual Drive Internal Square and External Hex for Tight Confined Spaces

All of these Carbyne Super Short bits are worth their weight in gold. High quality tools and they feature 1/4 or 3/8 drive and able to use a combination wrench on them as well. The best tool for limited access bolts.

I changed the rear brakes on my wife's 2013 VW Jetta Sportwagen today. The caliper brackets are held on with two big bolts with XZN cap heads - 12mm, I think. These have to be torqued to 90 NM, then tightened an additional 90°. I used these for that - I used a ⅜" torque wrench, then I used a ½" flex head socket wrench with a socket driving the XZN bit. Took all my strength to get the +90°, but the bit held up great. Afterwards, I was able to pull the bit free with minimal effort. I've also used these on the screws that hold the axles to the transaxle output flanges. These bolts are kind of small, and it's easy to strip the heads. But I haven't had that problem with these bits. My only complaint is that they are quite pricey. But if you like to "buy once, cry once," these are for you.

These tools were recommended in a turbo swap video on YouTube. Purchasing these was the difference between doing a turbo swap in a MK7.5 Golf Alltrack from the top or without them, having to remove your downpipe (which means CV Shaft removal) among many others. For the price, it saved at least 4 hours of work and avoided a lot of frustration. These also fit many other bolts on the VW. They seem very sturdy, fit in their respective bolt heads perfectly, I am ecstatic that I heard about these before attempting the job. I will now be buying their Allen head and maybe Torx head sets in the near future. 15/10 Highly Recommend

Good quality product. I’ve had them for a while now and still holding up.

Nice stubby set. They do run slightly undersized, so careful with high torque applications.

nice low profile need it to fit between turbo and engine block and it did just that with enough room to get a wrench on it.

Needed these for 2000 Jetta. They worked very well especially because they can be used with a ratchet or wrench. They are strong, so won't round out. Well made, strong, and durable.

Came in very handy for use on my AUDI.

I will never know why these were invented ! This kit is the Cat's meow and works great. Nice neat unit, very good idea to make short and able to wrench. Very well thought out and constructed, thanks. (Just wish no one invented what they are used to remove/install !)
