Analogues

  • ISO 8100, 8102, EN 1665.

Benefits

  • DIN 6921 Bolts are Hexagon Flange Bolts.
  • The bolt DIN 6921 is made of acid-resistant, high-strength steel and goes through special galvanizing.
  • The bolt has an interesting constructive shape: the hexagonal head smoothly passes into the flange.
  • The bolt can be made with both full and limited threads all will depend on the length and diameter of the bonded material.

Operation

  • The outer diameter of the thread of the bolt stud completely corresponds to the European standards.
  • In addition to the built-in washer, which helps the bolt to self-center, you can use additional equipment (engraving washer).
  • In addition to standard lock washers, you can use universal washers with a ribbed surface.
