Info	Specific features of hexagon bolts with serrated flange: The flange enables built up forces under the bolt head to be spread over a larger area, consequently resulting in lower surface pressure. The serrated flange rim gives excellent self-locking properties. Large (oversized) holes and/or tooling holes can be covered by the flange. Washers are not necessary.
