CDI 3/8 Inch Drive Adjustable Click Torque Wrench, Range 30-250 In Lbs / 4-27.7 Nm (2502MRMH)

This is my 3rd CDI torque wrench that I've purchased from Amazon. This was bought to complete my set as I already owned the 1/2 and 3/8 sizes. I believe the heads are the only difference between these and the Snap on version. While I love snap on and have used snap on extensively along with craftsman and occasionally some husky brand stuff, these are absolutely amazing quality and accuracy for the price. I've recently installed a new clutch, brakes, rotated tires, and used this 1/4 size for torqing a slave cylinder to a transmission and some motorcycle and dirt bike maintenance. All torque wrenches have held up awesome and stay in calibration very well providing you zero them out when done, keep them clean, and store them carefully in their cases. I love that they come with a protective case and a certificate of calibration. If you like high quality tools and don't want to pay snap on prices definitely buy CDI. I haven't had any issues in 2-3 years, so that says a lot considering how much they are used. Plus, if they ever need recalibration I can mail them to CDI in Southern California for a reasonable cost. Others have mentioned that warranty is not effective if purchased through Amazon. I can't comment on that as I've never had a problem. Quality is hard to find these days, CDI definitely takes pride in their products and it shows with accuracy and durability!

I own several CDI torque wrenches, this is why: First, they look good -- chrome plating with laser etched markings makes a tool that looks great and will be easy to clean. I know its just a tool, but having a tool that looks good in your hand is more fun to use. The micrometer adjustment is in 10's around the dial so there is no adding or guessing what your setting is. I have used others in 15 lb graduations and this tool removes the fuss. Simply pull back on the spring loaded sleeve and rotate the main body to make adjustments. Let go and it locks right in. Others I have used have a locking dial on the handle end which can become loose and you lose your setting. The handle is just the right length. CDI has excellent customer support. I contacted them prior to ordering and a tech spent plenty of time explaining the specifics of their wrenches. I called the tech for an explanation on accuracy ratings. This wrench is accurate within +/- 4% from 20% to 100% of full scale -- my certificate of calibration states values much lower than this (from .5 - 2.5%). 20% to 100% is industry standard though some torque wrench's will be accurate to +/- 3%. In this case 20% of 150 in/lb is 30 in/lb. So this tool will be increasingly less accurate the farther below 30 in/lb you go. This is due to lack of compression on the spring in the lower range. Really this wrench should be labeled as a 30 - 150 in/lb wrench, corresponding to the included certificate of calibration (meaning: my cert. of calibration labels this wrench as 30 - 150 ft/lb). Just know that with ANY spring type click wrench the low capability should be 20% of max even if dial will indicate a lower setting.

I would definitely recommend this 1/4 inch torque wrench. I bought it for screwing my front strut tower brace nuts with specified torque value. I took it out of the case, pulled the knurled dial and rotated the handle to the lowest level then to the specified torque setting. I began screwing the nut with this torque wrench with less speed as it approached the preset torque range. I finally felt a sudden and abrupt movement of the neck of this torque wrench with subtle 'click'. I felt it reached the preset torque. Then I began screwing another nut the same way to hear subtle 'click' and noticeable sudden and abrupt movement of the neck of the wrench. I did crewing 4 nuts and unscrewed them with ANOTHER simple (not torque adjustable) 1/4 wrench. Before re-screwing them, I screwed them with the NON-TORQUE ADJUSTABLE wrench until I felt slight resistance. Then I made recalibration of this torque wrench by bringing it down to the lowest torque level and adjusting to a specific torque value. Then I screwed all of 4 nuts again with noticeable 'click'. 1) Every torque wrench manufacturers recommend you to bring it to the lowest torque level while storing and before use. 2) It seems wise to fasten the nut with decremental speed as you feel more resistance screwing it. 3) Slow and smooth movement would be necessary to realize a sudden movement of neck and/or slicking sound. ( I felt the clicking sound was not so loud.) 4) The knurled handle rotates smoothly and it was easy to fix it to a specific torque level. I appreciate the quality of this torque wrench. 5) You should have another NON-TORQUE ADJUSTABLE wrench to loosen a bolt or a nut. They say loosening a bolt with this torque adjustable wrench may ruin the internal mechanism and bring it to inaccuracy. 6) I still hope that the price would be lowered for more popular use.

Excellent inch/pounds torque wrench. High quality. I use it on my motorcycle all the time.

I had to put new lifters and a cam in my 2007 Silverado. I already had two Snap-On torque wrenches. One up to 250 ft-lb and the other up to 100 ft-lb but didn't have one that does the really low torque settings. Since I no longer work professionally as a mechanic I didn't want to buy a Snap-on in the neighborhood of $300. I learned that CDI make the Snap-On branded torque wrenches with the only differance being the ratch head. This turned out the be a very nice torque wrench at a perfect price point. Anything cheaper is total junk and anything nice is priced really high. Only complaint is the ratchet head, not as nice as a Snap-On but I'm really not complaining for the price. I would definitly buy another CDI torque wrench if the need came up.

This is the nicest torque wrench I've owned, after almost 5 years of use on different motorcycles, on critical bolts it's been very reliable with a smooth click motion. It feels consistent. Would recommend as a tool you can "trust" without breaking the bank. Only complaint is the reverse/fixed switch stays in place but could be a bit firmer (easy to knock out of position).

I have the 3/8's version of this series of torque wrenches, and that one is a solid tool. Very heavy, everything from the ratchet lever to the grip feels 'substantial'. Spot on. This wrench doesn't have that same feeling. The ratchet lever at the business end is very sloppy, and the whole thing just feels 'off'. Granted, it's a 1/4 inch torque wrench, and at that size it might be hard to not have it feel like a toy, but somehow I guess I expected better. Well, and I would think that the need for a 1/4 inch torque wrench isn't great with most people. The case is nice. It's important, if getting the right torque is important to your work, to take good care of your tools. I'd still recommend this one, or this brand, if someone needs a good tool that has been tested and certified for the levels of torque it produces. It's still, this one, a very impressive tool when compared to cheaper more plastic competition. CDI does make 'less expensive' torque wrenches, but I wanted one that was mostly metal. I've had the Craftsman brand plastic parts wear out, and that's frustrating.

Dollar for dollar, this wrench is a winner. In terms of fit and finish, it is virtually identical to a Snap-on torque wrench I own, which costs nearly 4-times as much. The Snap-on wrench may be more durable in professional use, due to what appears to be a more robust ratcheting head, but any performance difference is not immediately evident. I also own wrenches manufactured by Craftsman and Gear Wrench and it’s clearly superior to either of those. The construction is all metal and the knurled handle provides a positive grip. Torque settings are laser engraved and easy to read, and the spring-loaded collar positively locks the wrench to whatever setting you choose. Another feature that I really like about the CDI wrench, is the fact that you can lock the ratchet. This is very useful when you’re using extensions, or dog-bones. In my opinion, there’s nothing not to like about this wrench. I just purchased it a short time ago, so I can’t speak to its long-term performance or durability, but I have no reason to believe, that with proper care, it won’t last a very long time. I think this is a great wrench for the money and I would certainly look to CDI for my next torque wrench purchase.
