We are a jobshop and have purchased most of our u bolts from McMaster Carr due to time constraints involved with our orders. We are mostly a repair and maintenance of production line equipment company so next day or same day delivery is usually the case on our material purchases. I do appreciate your interest in recent orders which have been capably handled by John Junior. His response to questions involving changes or additions to our orders have been timely and solved our problems.
