Love these engineering calculators. It is so quick to look up needed screw size plus other information for designing products. Liked it so much that I bought one for my partner

My inner nerd was so excited to get this after losing a similar slide chart that is out of print.Text requires readers or better lighting than the pub I was in when I giddily opened the package.

Quickly allows you to find fastener dimensions with no fuss. I'm a mechanical engineer as well as a handyman and this is great when repairing "things" around the home and auto. Face it, most people in hardware stores and big boxes are not well versed. This allows you to find what you need and get to work.
