About the 3205435 Fastener
Bossard article 3205435 is a countersunk (CSK) head thread-cutting screw, thread designation KB 22, 12 mm nominal length, in steel with a zinc-plated, blue-passivated finish, per the item designation. Thread-cutting screws form or cut their own mating thread as they are driven into a pre-drilled or cored hole, removing the need for a separately tapped thread or nut; they are widely used for direct assembly into metals and engineering plastics. The countersunk head seats flush in a matching countersink for a clean surface finish, and the zinc-plate-plus-passivation finish provides corrosion protection for indoor and general-service use. The part is identified by the Bossard article number stated in the designation; thread form details for the KB designation are held in Bossard’s catalogue documentation.
