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.

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.

Huge variety, reasonable price, great customer service They have a huge variety of hardware for my needs. Price is very reasonable too. I placed an order on Monday, it was supposed to be delivered on Wednesday but UPS lost the package. I called McMaster customer service and they got me sorted out immediately. Would buy from them again.

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
