HRB 4-Piece Hex Screwdriver Set 1.5 mm 2.0 mm 2.5 mm 3.0 mm Titanium Hex Screwdriver Tool Kit for Multi-Axis FPV Racing Drone RC Quadcopter Helicopter Car Models

These are high-precision wrenches. The handles have a machined, (knurled), surface, for a great grip. The set screws on the handles hold the shafts in place and are of top quality. No slippage, no loosening, after 2 years of regular use.Interestingly -- some, people (in-experienced, I presume), have complained, that, the tips, are difficult to insert into a screw head. This is only because they are finely machined, and, they fit, snugly. I've had this set of drivers for 3 years, now, and the tips have shown no sign of wear/rounding.Actually, they are VERY accurately machined - the people doing the complaining, simply, have used inferior quality hex wrenches in the past; particularly, the softer, metal, alloys that wear out, quickly (e.g., zinc-alloy). These, don't, do that.The tips on these drivers fit, snugly - like a glove - into a screw head, with NO amount of PLAY. It actually takes some getting used to, sure- but, you won't regret not having STRIPPED SCREW HEADS anymore, because of a loose, incorrectly, fitting, tip.As a pleasant surprise, the handles have end caps on them, complete with o-ring seals, to keep moisture out and store other small objects in, such as screws, spare, hex wrenches, etc.After almost three years of use, my driver tips show, absolutely, no wear whatsoever. I've even inspected the tips under a jeweler's loupe; no visible signs of wear.(There is one thing I could suggest, however: that is, that the end-caps are not, quite, as snug as they could be. I've remedied that, with a bit of silicone, applied to the o-rings, at the cap's perimeter.)

These drivers are made from quality metal and have not deformed, as many budget brands do. The price is very reasonable. They are lightweight and fit comfortably in the hand. The knitting has a good grip to it and they look like many of the other standard handles. Cant go wrong.

Learned the hard way that assembling kits require some tough tools. Especially, the 2mm. Other than that, for maintenance, these are great.I use factory team tools for initial assembly, typically. If they break (none have in 20 vehicles) they'll replace it. These, on the other hand, are a great set for maintenance. Recently upgraded an AE B6.2 to titanium hardware and these fit snug and worked incredibly well. Versus my team tools, these are fine for track-side pits doing maintenance between races and practice.I'd recommend these over pricey team tools. However, know that they're NOT as tough as team tools. With that in mind, assembling kits, know that cutting fresh threads into plastic parts will stress the heck out of your tool tips. Not something you wanna cheap out on, but also know that lubing your screws (PTFE grease is my own preference) before you start on them will save those precious, 2mm tips. With that said, these helped me assemble a brand new B6.2D without a single issue.

Amazing rc tool set. Only reason for a 4 star is the little silver tops come off very easy and I’ve already lost 1. Still great tools highly recommend

For the amount they cost they have held up well. Still using them to work in my RC truck.

My son is totally into Traxxas RCs and finds it difficult to find tools that do not strip the heads or round off themselves. I bought him these and he has not had to purchase another set since. Great product.

Great set of metric hex drivers for an affordable price. Use them all the time to work on RC airplanes. Also size is printed in big bold letters on handle so you can easily see what size you reaching for.

So much better than an Allen key. Lets me screw things in straight yet apply good force. One of my bits came loose and fell out, but the bit is held in by, would you believe it, a hex screw of the size of one of the other screwdrivers! So I just had to tighten that screw with a different screwdriver, and it's good as new. So, while it's more expensive than just some Allen keys, it's super worth it if you're going to use them frequently.I think it would be great to see other bits sold separately so that we can switch out bits using this assembly, as my eternal problem is many mismatching screwdriver sets because I can't just replace one bit and have them all match.
