Most customers don’t realize that Mcmaster is an industrial parts distributor, not a manufacturer. They have built a comprehensive industrial parts catalogue of quality American manufacturer as well as offer some premier European and Japanese. So if you ordered a packet of bolts, it may come in a packet with a brand logo you expected. But if it’s a pressure gauge, it will have been manufactured by another Company with their branding on the item. Don’t get alarmed if that is the case!
