Mounting and fastening system and mounting bolt

The mounting and fastening system of claim 1, further comprising:

• a clamp including:
• a clamp inboard surface extending transversely with respect to the axis,
• a clamp outboard surface extending transversely with respect to the axis,
• a clamp outward surface extending between the inboard and outboard surfaces,
• an incurvate tapered surface extending between the inboard and outboard surfaces, and tapering in an axially inboard and radially inward direction for cooperation with the tapered outward surface of the mounting adapter, and
• a rail mating inward surface extending between the inboard and outboard surfaces. The mounting and fastening system of claim 6, further comprising:
• a clamp and rail assembly having an inboard-outboard axis, and including:
• the clamp;
• and
• a rail including:
• a rail inboard surface extending transversely with respect to the axis,
• an oppositely disposed rail outboard surface extending transversely with respect to the axis,
• a rail outward surface extending between the rail inboard and outboard surfaces,
• an incurvate tapered surface extending between the rail inboard and outboard surfaces, and tapering in an axially inboard and radially inward direction for cooperation with the tapered outward surface of the mounting adapter, and
• a clamp mating surface extending between the rail inboard and outboard surfaces, and configured for surface contact with the rail mating surface of the clamp.

A mounting and fastening system mounting bolt, comprising:

• a head including flat opposite sides and semi-cylindrical opposite sides interposed between the flat opposite sides;
• a shank extending from the head;
• an external thread on at least a portion of the shank;
