Scenario: It’s 3:36pm on Thursday, and you need a new Helmet Respirator and Abrasive Blaster system by 9am for some heavy-duty, morning sandblasting. Lucky for you there’s McMaster-Carr and their website www.mcmaster.com.

Well, I’ve actually never needed a Helmet Respirator and Abrasive Blaster delivered overnight, but with over 480,000 components in stock McMaster is one of the most useful tools in our ability to quickly create physical prototypes. If you haven’t experienced McMaster-Carr, you should do the following:

1. Finish reading this post
2. Open a new tab in your browser and go to www.mcmaster.com
3. Search for something like “Bolts” or “Aluminum”


We frequently use McMaster to source mechanical components such as fasteners (bolts, screws, nuts), raw materials (plastics, aluminum, steel, etc), pneumatic and hydraulic fittings, electrical power connectors, and many other items. It is often my first stop when searching for a mechanical component. A huge inventory combined with a simple online interface and next-morning delivery makes it one of the most efficient and valuable suppliers we use.
