Fixing holes

V-holes with 90° bevels The selection of rails with 90° countersunk holes is based on the precise alignment of the threaded holes for installation. Here the complex align ment of the rail to an external reference is omitted, since the rail aligns during installation by the self-centering of the countersunk screws on the existing hole pattern.

C-holes with cylindrical counterbore When a rail with counterbored holes is delivered, the Torx ® screws are provided in the right quantity. The cylindrical screw has, as shown, some play in the countersunk fixing hole, so that an optimum alignment of the rail can be achieved during installation (see fig. 58). The area T is the diameter of the possible offset, in which the screw center point can move during the precise alignment.
