As far as MRO suppliers go they are the best! As far as MRO suppliers go they are the best! Pricing is usually in line with other MRO suppliers & their online catalog is easy to use & find items. They don't tell you in the catalog what brand you are getting (unless you can identify by the picture) but usually it is a trustworthy name brand. I would say Grainger & MSC are their biggest competitors. Would advise to avoid Grainger, I deal with them on a weekly basis because my company pushes us to use them - their prices are way high, sometimes double! Their website is terrible!. I don't use MSC very often but I would say they are very similar to McMaster.

Nonsense shipping policies At first they let me know I was able to receive the order in Mexico, however I decided to receive it at El Paso, because of the shipping price, without explaining them further info They let me know they can't ship my order to any address inside the U.S. since I'm probably going to take the order outside the country and they take a "conservative approach to shippments outside North America" Literally only ordering 4 locating pins... Reading the rest of the reviews I found out they really don't like foreign people, I thought it was only for the Mexico thing, but nah

Bizarre customer service. Checkout procedure on website doesn't provide a shipping quote. Received an email requesting additional information for shipping. Provided information and asked how much for shipping, got a reply back from someone else saying the order is cancelled due to non payment...

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!

The Standard to go by I order from McMaster-Carr on a regular basis. I do not believe you will find another company that does "it" as well as them. They are the standard that all other companies strive to achieve. Website works well, ordering is a breeze, excellent customer service, ship extremely fast and cheap, billing is quick and accurate, products are as described. Will always order from McMaster given the choice. Only exception is having to watch for items that will go truck freight as that is not always apparent when ordering. Love doing business with this place.
