Easy to use
I have been wanting to sort my nuts and bolts for some time now. At last a simply but effective tool to assist that job. With the 34 bolts for thread checking and 8 plain holes to check rod diameters it is so easy to pair loose nuts and bolts. Wall mountable and with rubber feet to grip and protect surfaces it is a great addition to my tool kit. Well worth the cost.

Can easily work out the correct screw size and thread
I've needed a replacement bolt for a table for quite sometime, not known how to find out the correct length or thread count.Now I can.Will never be stuck trying all different screws or bolts again.Extremely easy to use. Self explanatory really

Solidly made and accurate
Really handy tool for measuring bolt sizes. If you have one bolt and don't know the size, but want more, then use this handy size/thread checker to get the correct size and thread. It has imperial and metric sizes so it covers a wide range of bolts and nut. It's accurate and easy to use and I'm very happy with it.

Screw diameter sizer
Really useful screw thread sizer. Sturdy construction and tough finish to the face to protect from scratches to the metal. Accurate sizing from my uses so far- just a big pile of assorted screws to get through now

Convenient thread checker
This panel is very convenient, don’t have to guess what diameter or thread size for any nut or bolt listed. Sturdy and very precise.
