McMaster-Carr is fantastic! I've been using McMaster-Carr for years. They always have the bolts and other hardware that no one else has. They also have very good pdfs with dimensions as well as CAD renderings. These are very important when your building prototypes and trying to figure out what may or may not work on a one off project. The best part is you get them either the next day or the following. Highly recommend!

incorrect orders every time. All orders have have been either incorrect quantity or incorrect sizes. Even after reviewing orders many times prior to ordering. Terrible communication skills. Great shipping, things arrived very quickly. If they had been correct even once would be 5 stars.

Best source to quickly find hardware and other supplies. Freaky fast shipping too!!! I use McMaster-Carr primarily for automotive needs. Using their web site is super easy by far the best site to quickly get to what you are looking for with no fluff or "offers" to interrupt navigating your way around. Finding hardware and electrical supplies is a breeze. I highly recommend using them if you are in the SouthEast. Most everything I have ordered literally shows up the next day even though I didn't select next day shipping. They may not always have the best price but the quality of goods combined with showing up the next day wins in my book. No one at McMaster-Carr asked for this review. I just felt I needed to share with others how awesome they are to work with.

To whom it may concern To whom it may concern : Will call team member Tommy Ortega is the most processional / talented / nicest person at this McMaster Carr location , he’s all over the place very Knowledgeable, respectful among other things that I Might be missing out , I’ve been coming here for over a year and not once he’s made a mistake or left any thing out from all the orders that we have placed . Thumbs 👍🏽 up and keep up the good work Tommy !!! Sincerely : A very happy customer 🙂🙂🙂🙂

Great Customer Service I buy alot of stuff from McMaster Carr with me being a maintenance manager. Almost everything I order is delivered by the next morning. I have always received quality items. Today I received one wrong item in my order. When I emailed their customer service I received a reply within 10 minutes. I was told to keep the wrong item and they would ship the correct item for the next morning delivery. Anyone else would've wanted pictures of the wrong item in the package and days if not weeks of time before a reply.
