Engineering Screw Chart, Screw Data Selector, Screw Selector, Screw Chart for Engineers, Drafters & Machinists

Great charts that are hard to find. Alwats good quality from this company. Highly recomend.

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.

Lots of great information, I especially love the bolt clearances

I run my own mechanical design consulting business ([...])and have been using a smaller version of this slide chart for several years. It has been an incredibly useful tool, but it was only in inches. I found this one a few days ago and ordered it - it is AMAZING. It also has about a dozen other things that my old one didn't have: Min bend radii for sheet metal in various materials Reference durometer data for various materials Beam defelction equations Thermoplastic properties for various materials Surface finish reference data A few simple stats equations Weld and GD&T symbols And more... ...and then of course the standard stuff like dimensions for the full spectrum of nuts and bolts, drill/tap/size chart, fractional and drill conversion chart. This is a huge time-saving tool for anyone who is in the product development/mechanical design field.

They don’t make them like they used to, but this will work.

I am an avid user of technology. I own a graphing calculator, iPhone, iPad, 2 laptops and a desktop, and use all sorts of software for productivity, yet I find this little slide rule to be as equally indispensable. It's great to pull this little guy out and find all the info I need for fixture or prototype design. Absolutely worth every penny and I recommend it to every new engineer or any engineer who doesn't have one. You don't know how useful it is until you have it. People have already mentioned the features but I will state my favorites. The beam bending calcs are great as I tend to use a lot of snaps to simplify mechanims. I also use the screw finder for fixtures and prototypes so often than I now feel nearly useless when I don't have it. These two things as well as the thermoplastics shortcut list are worth the price of admission. Don't hesitate, buy this slide.

Great product and I had high hopes. I am actually happy with the product but the packaging resulted in signifixant damage to one edge. The item was clearly labeled to not fold it, but that was covered by delivery bag was was not labeled to not fold it. Fortunately, despite the damage, it is still usable. Great product that adds lots of info and will be heavily used, but I would have preferred my use of the item to cause the damage.

The product was exactly as described and is very well made. Would buy again.
