My experience with McMaster-Carr has been OUTSTANDING My experience with McMaster-Carr has been outstanding. They're customer service team is always approachable and amazing. They respond to you real quick and they deliver the product to you before the promised date even, I really hope my hospital works with them and gives them more business in the future. At a time of need such as the COVID crisis: They have been responsible and amazing!

Shipping Cost Surprise - Huge! I recently placed a small order - just over $20 - with McMaster-Carr. During the order process I was not able to see, or even estimate, the shipping cost. All I got on the order page was "shipping and tax will be added." OK, I figured, I'll take a chance. 24 hours later, my shipment was in the mail and I finally got a receipt showing the shipping (and tax) amount. Turns out the shipping was more than 40% of the total order, making it substantially less competitive with other suppliers. My advice: (1) shop around. (2) If you MUST buy from McMaster-Carr, don't press "buy" until you know the shipping cost.

Poorly managed, non customer centric business. Customer service is arrogant and unprofessional. Shipping policies are absolutely mental, I don't think they want business? Products are equally poor. Received a rusted and bent bar that looks as though I could have bought off of Ali-x for a 5th of the cost. All kinds of stupid rules regarding shipping. They are not customer centric. No reason to do business with them at all, deleted my account. So many other companies deserve my patronage more than this one. Hope this saves someone some trouble.

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.

Find anything. Have it at your door in 2 days. 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.
