Useful and well crafted
One of the best deals on Amazon. This is entirely machined metal with a beautiful metallic blue finish. This was built to last.I was genuinely stunned at how nice this one was when I opened the package.It has many smaller sizes for metric and SAE which is appreciated.

Vital tool for any shop
Great product, l’ve struggled with guessing bolt and nut sizes and now I have a tool that measures them for me. Its construction allows for easy use to determine bolt/nut sizes and type.

Professional Quality!
Very professional quality. I was expecting them to be well built, but they completely exceeded my expectations. Heavy aluminum construction, with stainless steel bolts. Labeling is extremely clear with metric and standard rulers on the sides for length measurements as well. I couldn't be more pleased with my purchase selection for this item. Easily worth the price.

Well made quality part for all workshops.
I am constantly salvaging hardware from old machines. With the prices skyrocketing for just a bolt and nut, it makes sense for me. This handy tool allows me to know quickly and easily which pieces will work and which will not. It also lets me make a well informed trip to the hardware store when my own personal stock does not provide a solution. Great purchase.
