Bolt 1/4-20 x 1 in. Grade 5 Zinc-Plated Hex-Head Serrated Flange

These serrated flange bolts are hexagonal head bolts featuring a flanged washer face that includes serrations on the side that contacts the surface. They are intended for use in situations where vibration occurs, as the teeth engage with the surface, requiring more force to loosen the bolt than to tighten it. In certain applications, the integrated washer removes the necessity for a lock washer or lock nut.
