Torque Screwdriver Wrench Set (10-65 In.lb ±1) with 29 S2 Alloy Bits & 5 Drive Sockets | 1/4" Socket Adapter for Tools, Bike Repair, Mounting | Includes Portable Case

Seems accurate and quality craftsmanship. Truly a must have to install optics properly. Nice selection of tips/bits too. Now a part of my armorers toolbox for sure.

Edit: Seller remedied the issues with the product and was resolved quickly. Excellent cutomer service!I bought this due to the many 5 star reviews so maybe I just got a lemon. . .The torque driver is easy to use. Set to torque using twist knob and go. Very simple.However, when it comes to precise set ups it lacks. The red bar indicating the torque specs is fairly large compared to the number scale used and could easily be off by 2-4 in/lb depending on how you read it.With that said it worked great the first few uses. I set to what was believed 18 in/lb and tightened a couple rifle optic mounts. . Great, worked as it should.Using this to mount a pistol optic plate at (I presumed to be 12 in/lb) I wasnt paying attention and the it never clicked to spec. . Snap! The head of the aluminum bolt sheared and ended up striping the threads. New bolt and mounting plate were needed after that.Looking back I wish I would've went with a reputable name brand. Would've saved me the additional cost of screws and a new mounting plate. . .

I did not want to spend a lot for a torque screwdriver. I had lots of electrical wiring to do on a recent project, but I might never need it again. I hoped that this unit would be better than the cheapest ones. I have never owned one of these before, although I do have torque wrenches that I use for much larger fasteners, so I was not sure what to expect.I am pleased with the result, but am giving only 4 stars because of lack of instructions and information.I am not reviewing the bits included with the driver, though I did use the hex to square adapter for the measurements that I report here. I used a bit from a separate set to tighten my actual electrical connections.No instructions are included with this torque screwdriver. The listing description says that it is settable to 1 inch pound, so I thought that the rotating knob at the end of the driver would have graduations of some sort. No such luck.My first impression on tightening a screw was that the action of the driver was "gritty". This seems to have improved after some use, or it might be that I have simply gotten used to it.At first, it seemed clear to me that the driver did not work in both directions, but only for right-hand screws, as it did not release on just tightened fasteners when turned counter-clockwise. Later, I realized that it did release, but that it required more torque to release in the CCW direction than the CW direction. About that same time I realized that the two-headed arrow at the top of the torque scale on the driver almost certainly meant that it was meant to work in both directions.It turns out that the locking knob at the end of the driver has 12 locking positions per revolution. And it turns out that one revolution of the knob moves the torque scale by about 6 inch-pounds. Thus, each "notch" on the knob corresponds to a torque change of about 0.5 inch-pounds. Where they get 1 inch-pound settability they quote I don't know.I decided to raid my junk box to set up a simple calibration facility so that I could be sure to tighten my screws accurately to 20 inch-pounds. As you can see in the photo, I used an old grinder to provide a rotating shaft that has very little friction or play. I used a scrap of plywood to provide a lever arm of 5 inches (that is, I drilled holes at 5 inches from the shaft in each direction along the bar). I clamped this bar to the shaft using the washers originally meant to clamp a grinding wheel.I loaded a basket with 4.06 pounds, as you can see from one of the photos. That is within 1.5% of the desired 4.00 pounds; accurate enough for my purposes.I started with the basket on the floor, and the string looped through holes in the basket and one of the holes in the lever arm. I tied off the string so that the arm was horizontal when the string was just taut. I then adjusted the screwdriver until the basket was just lifted off the floor before the screwdriver released. One of the photos shows this setup being used for testing the release torque in the CCW direction.One photo shows the torque scale with the driver set to release at 20.3 inch pounds in the clockwise direction (i.e., for right-handed screws). The other photo shows it set to release at that same torque in the counterclockwise direction. Interestingly, both settings align one edge of the red bar with the 20 inch-pound graduation, but at the two opposite edges of the bar. There are 6 "clicks" of the locking knob between these positions, which corresponds to a 3 inch-pound difference. Note that if I had set the red bar to be centered on the 20 inch-pound graduation, I would have achieved a torque approximately 1.5 inch pounds too low in the CW direction, and approximately 1.5 inch pounds too high in the CCW direction.I wrote this review and took these photos a few weeks after I originally calibrated the driver and used it to tighten my several dozen screws. I was very pleased to find that the torque provided by the driver did not change from the way that I had originally set it.

Did what I needed and wasn't too expensive. Seems to be holding up to use so I would recommend it.

I've been looking for a new torque driver for a while since we lost our last one at the range. We use this to torque scope mounting bolts as well as for slide optics like RMR or Halo. Pretty simple device, just set your torque limit and turn until you hit that limit just like any other torque driver. The unit seems fairly robust with a nice plastic case and multiple options for driver bits as well a socket adapter and some small sockets for smaller nut driving. My one complaint if any is the lack of extension. the driver is fairly bulky and if you need to get into a tighter space it would be nice to have a magnetic bit extender that would allow a narrow shaft to access tighter areas. For what we need it for this isn't an issue but could see it being so for others. Simple fix could be a few longer shaft bits but the extension would be the most universal.For the money this is a decent deal for a well built tool that functions as designed. We didn't have a reference driver to compare the settings against but our use it's critical if it's off by a few inch pounds.Overall a nice deal if you need a compact torque driver.

Well made & cased! Product as described👍

Good product

Got this in place of a name brand and it works great for my purposes.
