Review: A must for every garage. Super value. Includes most common sizes. - After years of guessing on fastener sizes and having to go back and forth between the car, the parts bin, and the tool box, I finally got wise and ordered this set of thread gauges. It includes pretty much every size you'll run into working on most vehicles with the exception of huge suspension fasteners for like shocks, CV axles, and other large bolts on the frame of the vehicle. I actually do quite a bit of mobile mechanic work so I really appreciate the sturdy plastic carrying case these come in because it's easy to take it from my toolbox to my truck and the case keeps all the gauges in place. I'm also impressed by the machining and finish of each gauge. They are clearly marked and color coated for metric and SAE sizes. I think this set was a tremendous value and they are a must for anyone who fixes cars, motorcycle, boats, or anything with nuts and bolts.
Review: Worth the purchase - Definitely helpful to have around. Yes they have something similar at the hardware store but that does not always help you when you need to measure something at your house or cannot remove and take to the store to find the size. Have used many times, they quality and value are worth it. They have been accurate and the case is nice quality to keep them stored.
