This application can be really handy! Are you tired of spending a lot of time when your at the Hardware Store, just finding the right size bolt? This application can make that problem go away! Just hold the end of the bolt up to one of the dots on the screen and the label tells all! You don't need to carry one of those old plastic drill gauges around anymore, plus, this is free! Please post your comments on your experience with any suggestions. I will try to work with them to make it easier for you. **Note** This is Not meant for sharp objects such as screws, it's for flat objects like bolts or the flat of a drill bit.
