Bülte’s snap-in clips require simply pressing together both pieces for fast and easy assembly. The action of the interlocking gripper teeth creates a bond that is very diffi cult to remove without damaging the clip. The standard materials are natural Nylon (Polyamide 6.6) and natural Polyacetal (Delrin, POM). POM resists hot water, greases and oils. These clips are vibration, corrosion and abrasion resistant.
