Best App, Best Supplier Ever

McMaster-Carr is always there to answer your questions, even though it’s not often that you will have a question because their app and website are so neat, well organized and full of and relevant information that you may seek. As someone who is often looking for new ways to do things and finding new materials to work with, McMaster’s descriptions make that a breeze. Any item you view will almost always be described as though you are learning about it for the first time making it very simple to find what you’re looking for, when you don’t know what you’re looking for is called or looks like! Shipping is also very reasonable and once you have a feel for their rates you will not second guess how much they are going to charge.

Thank you McMaster for great service over the years!

Above and beyond

Better than any other shopping app, in any field, for any use. At least half of the credit (likely more) goes to McMaster-Carr, for the incredible detail of their data on every product. The catalog is equally an engineering/design handbook, with specifications, mechanical drawings, 3D models, and more.

Some of the drawings and models are not available through the app, but can be had from the web site. The app has an advantage in speed when searching or filtering.

Great app design and supplier

I’m a small 2-man manufacturer, and McMaster-Carr’s website is a joy to use. I browse this app sometimes just for fun if I’m bored. This is a great company that focuses on supplying higher quality components. (They find USA-sources for parts I didn’t even think America made anymore. This ain’t Harbor Freight guys/gals!) I’m in a metro area, but my elderly father’s business is in the country so industrial suppliers are distant. McMaster-Carr has helped keep his business alive.
