McMaster-Carr FAQ

Is McMaster-Carr legit?
🤔 The McMaster-Carr app's quality is mixed. Some users are satisfied, while others report issues. Consider reading individual reviews for more context.
Every engineer should have this app for plant design/maintenance. But it’s the company behind the app that is really special. The best customer service you will ever experience. Pick up a phone and call them. You will get a live person who is knowledgeable and willing and able to help.
Good app but needs some refinements
The simple catalog layout and graphical interface is easy to understand and well categorized. It is similar to their website layout.
However, the navigation in the app is a bit confusing at times. The navigation tools are at the bottom right of the corner of the screen which is awkward locations. It also doesn’t work half the time. Every other app has it at the top left of the screen. The app could benefit from having a toolbar or ribbon for easier navigation. For every hardware folder you click on, it should make a new tab showing the category name every time one is clicked on. Some hardware items have many subcategories and it would be nice to see the path I used to get to a particular item.
Some other things to note is it is a little buggy, like the screen would shift slightly for some reason. And occasionally it would freeze and not respond to touch, forcing me to restart the app and losing my progress searching for parts.
Great app and company.
Great, easy to use app and McMaster-Carr has Greta service. For me living in Pa and their warehouse being in Ohio, I get my orders the next day. My new go to for hardware.
Superior
Great customer service, straightforward, no nonsense, website! Love it. Most items arrived next day. McMaster Carr is what Granger wishes it could be. I’m always shocked at how few people know of this superior supply company.
Incredible, simply the best!
Everything about McMaster Carr is exemplary.
Please add Apple Pay as a payment option.
Legendary app
This is how you make an app. Really amazing and even better than their legendary catalog. I only wish I lived near a distro center cause the shipping can be prohibitive for a hobbyist.
Once Great
McMaster Carr was once a great company. Used to be next day arrival. Now it’s hit or miss if you get your order. Not worth paying the outrageous prices when you can get it a 1/3 of the cost and actually get it the next day from Am*zon. And they carry just about everything McMaster does now. Guess they couldn’t keep up. No place to go but up I guess.
Superior app & service
I've been purchasing items from McMaster-Carr for decades. The shopping experience has always been first class, even before the app. With the app, I'm able to quickly narrow down the specific item I need and get it ordered. I'm relatively close to their warehouse so shipping is always just one day. Awesome.
It’s a great app if you have the eyes of a 12 year old.
There are only a handful of apps out there that do not allow the user to increase the font or text size. McMaster Carr is one of the few dinosaurs. That is correct, it will not increase the font size even in iOS 15. I have joined the team to review new versions, and frequently asked about the ability to increase the font size, and was told it was not in the plan. It’s an absolutely amazing company with an absolutely amazingly bad app; it just doesn’t make sense.
The next best thing to the paper catalog
Why am I not surprised that McMaster’s app is also excellent? For chumps like me who don’t merit a paper catalog, this is a great tool.
