Slips and lock nut is impossible to losten

Would Not Recommend

The square slips with little pressure, and ironically the thumb nut locking it in place is very difficult to loosen.

Great option, but not the best for the money

Would Recommend

This 6-in combo square came square without any adjustments required, which I was happy about. I have Irwin's 12-in combo square, and I think it's better made for a similar price. I'm splitting hairs, but the scale readability and the finish are better on Irwin's, but I can only find it online. The nut on Johnson's is much better. Overall, this is a solid option, and I have over-thought it.
