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.

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.

The media could not be loaded. *****UPDATE 05/26021*****Screwdrivers still work great. I have noticed that the magnetic tips have seemed to weaken and im assuming theres a magnetic coating on the tip that wears off over time. These have saved me soooo many HOURS of not having to mess with the tiny L shapped Hex Keys that are standard. The 1.5mm hex driver tip did snap a few days ago, but in all fairness i was applying a good amount of torque when it snapped. Overall i took 1 star away because i have to buy a new pair now becUse there no longer magnetic. ALSO customer service was great and very responsive, they replaced the first pair i had because there was an issue with no questions.*****ORIGINAL*****Ive been looking for a set of allen head screwdrivers for the last month. Researched the ones around this price range and these seemed to be the best. I was a little concerned because i read a couple reviews of the allen heads snapping off when torque is applied but those people must have been turning way to hard because they seem really durable to me. Great product!

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.

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

Got these for my rc cars and have not been disappointed. Still not rounded after almost a year's worth of hobby use.

The actual working part of the hex drive needs to be a touch longer,as you use them they inevitably will wear out;easily fixed by grinding a little off the end.just need a bit more of the end for grinding.also the caps on the handle could be threaded instead of an o ring which comes off to easy.but in all I use the crap out of these daily, not bad at all.if you want real quality you'd have to step on a snap on truck and pay snap on price. These are good enough.
