Material: Steel C45, black oxide finish. Screw steel 12.9.

Typ B1: With two axial mounting bores.
Typ B2: With two axial mounting bores, with sunk holes for cylindrical cap screws DIN 912.

The thread of the screw DIN 912 is covered with a layer of polyamide.
Tolerance b: +0.08mm / -0.25mm. Temperature range: -40ºC to +175ºC.
