that fits my holder with the set of taps and dies I have. 5-40 is an unusual combination of size and Increment, usually material is 4 - 40 or 6 - 32. I was happy to find this as I needed this size and it works well.
I wouldn't have bought this if I knew it was MADE IN CHINA. I tried to study the product to find out where it was made. When he came, I realized that I was unsuccessful. If I had known it was MADE IN CHINA I would not have bought this product. There are other countries that produce these types of products. I am very disappointed that Revain did not state the country of origin and I will no longer be buying Gyros Tools products.
