Material:
Screw, high-carbon steel, grade 10.9
Ball, ball-bearing steel.
Version:
Screw black.
Ball hardened, bright.
Note:
Surfaces which are not flat and parallel can be firmly clamped or supported with a flattened ball, the movable ball can adapt itself up to 9°.
Longer versions have been designed especially to be glued in. This enables mechanical connecting elements with male thread to be made cost-effectively for small and medium-sized series.

Form BV: flattened ball non-rotating
Form FV: flattened ball diamond grip non-rotating
