I purchased this 2 weeks ago to re-assemble the upper and lower intake manifolds on my truck. The bolts were small, with an 8mm hex head. Torque specs were 59 inch-pounds for Step 1, and 96 inch-pounds for Step 2.Because the manifolds are aluminum, and a very low torque spec on the fasteners, I decided to spend an extra $ 50.00 for a professional quality tool, instead of a $39.99 cheapie that you can get at Wal-Mart, etc. Tools and equipment are two things I do not skimp on in regards to cost.I followed the break-in procedure provided and was very impressed with the fit, finish, and feel of the tool. The certificate of calibration has the serial number of the wrench, the date of calibration, and three readings for each setpoint, both CW and CCW. ( See attached scan )This torque wrench is an absolute joy to work with. I honestly could not be more satisfied. Consistent results every time, and perfect for those tight spaces. Four of the bolts on the rear of my truck's manifold were approx. 2 inches from the firewall; you could feel them, but they were completely out of sight. I have complete confidence that they were torqued properly.In case you are wondering, this is an unsolicited review. I did not receive anything in return, as some of the reviewers mention in their posts. Nothing wrong with that, I suppose; their reviews were accurate and enabled me to make a decision I do not regret. I am not a professional, just an old shadetree mechanic who knows that you don't get top quality tools at a bargain price.I have just ordered the 3/8 inch drive " bigger brother" version of this tool. It will be invaluable for torquing the spark plugs on my truck's aluminum heads. Specs are 10 - 15 foot-pounds for that job. Another tool at $ 89.99 is well worth the cost. There is nothing worse than stripping the threads in a tight spot. (Speaking from experience on that)Have a good day.John Johnson
