Review on 🔧 SAE HSS Helicoil Thread Repair Kit - AKM 243Pc, includes Adjustable Die Wrench, HSS Drill, and Thread Gauge; Sizes: 1/4", 5/16", 3/8", 7/16", 1/2 by Sam Stone

I purchased this gauge expecting and hoping for a useful tool in my Automotive shop. Unfortunately, it turned out to be a waste of money. Thanks to my knowledge gained in practice, I was able to spot the inaccurate measurements from the start. The only pro is that it was cheap, but you get what you pay for. The cons are that it is inaccurate, poorly made, and will only waste your time. Steer clear of this product.
