Hi, this is Bob Sloan. In my life, I have successfully done many things that other people have spent years to perfect. I have work experiences as truck mechanic, diesel mechanic, predictive maintenance tech, manufacturing engineer, and scientist/physicist and I’ve been taking apart and putting together complex machineries for the past 30 years. I am very passionate about DIY (do-it-yourself) and I like teaching skills to newbies especially on how to do things properly and safely on their first try.
Looking For The Topnotch Tool?
When talking about car repair, you should only look for the right wrench that is worth your investment no matter what your budget is. Without learning all the facts and appropriate units, it is unlikely that you’re going to make the right decision.
Is Your Choice Good Enough?
It’s not about the product really. It’s about what you are going to use it for. In order to fix any auto repair issues and get the best output, you need to make sure that your choice of wrench is good enough for the task at hand.
Why Torque Wrenches?
Gone are the days where you could fix things with hammer, pry bar, and adjustable wrench. Estimating how much to tighten something mechanical or electrical can lead you to many issues that we won’t bother listing here.
That is why I believe that competent DIY people, who use either use traditional or digital wrench, follow manufacturer prescribed procedures, can make much better quality car repair, connections, and assembly.
Have you seen many electricians using torque wrench when tightening wire to the circuit breaker? In best case scenario, they claim that they can “feel” how much to tighten. Unfortunately, most of the time when you start feeling, you already over tightened the bolt. Manufacturers go long way in setting appropriate value.
The only way you can reliably reproduce it is by using a torque wrench to do it.
Even most experienced auto mechanic who say that they can “feel it” can be way too inconsistent, to the point where they apply 2-3 times torque specs. Given that it’s usually set at 75% of the load and over tightening the bolt 3 times, the value will load the bolt at the breaking point. Even normal operation of the equipment can put this bolt over safety margin and breaking down results. All most critical components need to be torqued to tight-tolerance. Otherwise, it can result to catastrophic failure.
