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