Are these thread gauges made in the US or "overseas:"? Thaks Max

I checked and the gauges are both made in the USA. I'm very happy I bought them. More complete than any others I looked at, although a little large at 2 foot long and 6 inches tall.

What is the warranty? After reading the reviews and the price. I think its' a question that needs an answer.

To be honest not sure if a warranty comes with these bolt gauges. I purchased this set about 5 years ago and am still using them. no problems. Even if with warranty , that would not be in effect now. They are made very well.

What is the pitch diameter of these gauges 6e/E, 6g/G or 6h/H?

Class of fit is not specified. The reference elements are grade 8.8 nuts and bolts supported in plastic. This is a great reference for placing near the bolt bins but not for inspection

Why is the price increase from $86.99 to $165.00 every Sunday and then lower to 86.99 again for the rest of the week every week?

I think there are a couple of sellers on Amazon that sell these at a discount in the 80-$90 range. When they run out, amazon will sub to a seller who is at list price. They probably don't run out too often. I've watched these over a year and haven't pulled the trigger yet.
