Serrated Flange Bolts & Screws

Serrated Flange Bolts & Screws

Have AQuestion

Armed with teeth-like serrations, serrated flange bolts are one-piece bolts bite into surfaces to resist vibration. This bolt is identifiable by the ridge or surrounding the bolt head, this built-in washer under the head of the Bolt acts to distribute the clamping load over a greater area. A flange bolt is designed to provide the same holding power as a washer.

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.
