FASTENERS WITH LOCKING COATING

NON-REACTIVE SYSTEMS (LOCKING SYSTEMS)

  • DIN 267, part 28
  • Complete, plastic spot or thread coating, which causes a locking effect when screwed in, and does not stop the connection from unscrewing but prevents complete loosening.
  • With threads of: nylon, aramide, metal (Cu, Al)

DIN 267, PART 28 SCREWS WITH LOCKING COATING

  • Tuflok, Clemm-Loc, polyamide spot coatings and complete polyamide coatings
  • The locking coating is not a lock to prevent unscrewing (like an adhesive coating), rather a retainer
  • In the event of high pretensioning force, the locking torque is not capable of preventing self-unscrewing in the event of a high pretensioning force
  • A balance is only achieved between the locking torque and the unscrewing torque with a low residual pretensioning force. As a result, the locking torque prevents the connection from unscrewing completely and falling apart

THE “BLUE SPOT” IS ALSO SUITABLE WHERE OTHER SYSTEMS FAIL TECHNICALLY OR ECONOMICALLY

  • For very small screws - from M 0.8
  • For screws made of a hard material
  • For screws that must not be weakened in the cross-section
  • For threaded pins

FASTENER WITH LOCKING COATING

  • Standard coating
  • Unless otherwise agreed, the coating length is 1.5 x d ±2P, measured from the end of the screw
  • The first 2-3 threads remain free in order to be screwed more effectively.
