Pros
Thickness 1/4", Length 8-3/4", Width 3-3/8 Color: Red
There are various packs of nails and screws and I had no idea what size they were. This tool is VERY helpful. Surveyed and marked most of his hiding place.
This is a great tool when you need a new nut or bolt. It's useful to know if your gear is metric or SAE. Worth the money because it helps eliminate the headache of ants going to the hardware store.
I don't know why I waited so long to get one of these !Pretty easy to use with very clear markings.It took me a little time to get used to the thread checker but it's great.Finally got my spare gear in order.
