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!

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.

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.

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.

World class company I’m giving them five stars despite their bizarre website tactic of blocking people searching for parts. They have an incredible catalog and more importantly, they’re shipping is world class. My orders typically arrive in just 1 to 2 business days which is greatly appreciated.
