N. B. : 1 000 pieces = 500 snap-in clips.
Hole Ø = diameter of hole recommended. Smooth head.
The references with length L=13.5 mm and L = 21.0 mm have a 5.0 mm non-threaded part under the head (the diameter is still “d”).
As a consequence, those products do not correspond exactly to the product plan above.
The total height of the parts to be assembled may vary according to the pressure with which they will be fitted together, and also according to the type of pieces that are going to be assembled.
Therefore, an internal test is recommended.
