An efficient connection

Böllhoff, as a specialist in mechanical joining technology, and DELO, as a specialist for intelligent bonding technology, have together developed a new fastening system.
It’s the ONSERT® technology – quick bonding of fasteners without loss of performance.

Your benefits:

  • Optimised design ensures distortion-free surfaces; ideal where close tolerance or visual requirements are important. Fastening elements do not become apparent on the visible side through
  • Heat input such as it happens during welding and heat curing
  • Processing parameters independent of customer component
  • Full mechanical load capacity immediately after irradiation (no post-crosslinking)
  • Short curing times (< 5 sec)


There are two product families in the DELO range of adhesive products that are suitable for ONSERT® adhesion.


Light-curing acrylate

Curing in less than 10 seconds

Universal adhesion to various substrates

Application specific mechanical properties (ultimate elongation, TG, Young’s modulus)


2K-acrylate plus light curing

Fixing by light in 4 seconds, technical strength after 60 minutes

Temperature range from -40 °C to +120 °C

Bonding process

  1. Dispensing
  2. Joining
  3. Curing

ONSERT® – The product range


ONSERT® basic – surface connection

A transparent plastic sheath is applied to fasteners. The geometry provides for sufficient bonding surface.

ONSERT® plus – ripp connection

The fastening elements are over moulded with transparent plastic (adhesive dome) and are then fitted using light-curing adhesive. Adhesive domes can be produced in various designs, e.g. with internal threads, bolt threads, ball studs or snap connections.
