McMaster-Carr is legendary in the industrial supply world for good reason. The catalog of over 700,000 products is astonishingly comprehensive, the website search is remarkably fast and precise, and orders frequently ship the same day. The detailed product specifications and CAD drawings available for most items save engineers enormous time. No other industrial supplier matches McMaster-Carr for speed and reliability of fulfillment. The trade-offs are intentional: pricing is not always the lowest, there is no free shipping, and the company deliberately avoids price comparison by not listing prices publicly until you have an account. No loyalty program exists, but the 30-day return policy is fair. McMaster-Carr is not trying to be the cheapest -- it is trying to be the fastest and most complete, and it succeeds at both.
