Super company

I've been using them since before smartphones when their website was THE place to go to search for my nuts,screws, bolts needs. Incredible detailed drawings so you knew what you were purchasing. And now via smartphone they shined again with one day delivery with regular ground price.

Very good customer service

Hi, I've bought many products and customer service is very good, they answer the phone,they look things up and straighten things out. They will request clarification if they are uncertain what was ordered, great company to work with.

Industrial supplier for just about any mech/engineering/mfg part in the world.
Prices reflect quality parts,not cheap imports. I can be reassured that I'm getting a genuine part that will hold up to engineering specs (for example- fasteners are excellent quality and hold exact tolerances, no cheap big-box import stuff).
Everything is easy to find, orders can be split up by PO or job type. Fulfillment/Shipping is an example of how pefect a system can run. I've made hundreds of orders and NEVER had a mistake or quality issue. Not the cheapest by any means, but my timeline and sanity are worth the tiny extra cost.

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.

Completely ridiculous shipping rules
Reviewed on 2021-01-27T19:24:19
Completely ridiculous shipping rules. I placed an order online to be shipped to my customer location (that I have shipped to previously).Received a confirmation email and then was subsequently contacted by a rep stating they intercepted my order so UPS could return it as they could not ship to a third party. If I'm paying by credit card, why do they care who I'm shipping my items to?? It mentions nothing about this "rule" on their website.

They do not tell you how much shipping…

They do not tell you how much shipping is going to be when you enter your order. I ordered a small quantity of metric screws and they could have been mailed for less than a dollar.They charged me $8.79 for shipping for $8.10 worth of screws..
They have quality products and have hard to find products, but their on line ordering system just sucks. All other companies tell you how much shipping will be before you finalize your order.

This is an excellent company to do business with. They have a truely incredible selection of products,both industrial and residential. Their online catalog is very easy to use. This week, I placed an order in the morning and it was delivered the next day. Some reviewers have complained about the fact that the shipping charge is not revealed when you make your purchase. This is a standard business to business procedure. I have been doing business with them for years both for personal and business purchases. Their shipping charges are fair, rest assured. People think they get free shipping with Amazon. Well think again. Amazon charges you 129 bucks a year for that. If you make 10 purchases a year that is $12.90 per shipment.

Reviewed on 2020-12-03T12:43:30
Shipping charge is not disclosed at any time when placing an order. There is no next page where you have shipping options!When you click on "Place order" it is the final step and they can charge you whatever they want to for shipping.
In fairness, their website is otherwise easy to use and the company responded within minutes to my concerns. The order arrived quickly and shipping charges were refunded to me after my complaint. If the shipping charges issue is resolved I would likely purchase from them again.
