A mounting assembly for attaching a first object or structure to a second object or structure in a blind installation. The mounting assembly having a frame locking bolt (FLB) that includes a bolt head flange and a frame bolt with a bolt head. The bolt head and the bolt head flange are configured to locate within an enclosed space and not accessible for torquing. The bolt head flange having a first edge and a second edge and wherein the second edge is configured to locate next to a solid wall inside the enclosed space to provide resistance for threading a frame nut onto the shank of the frame bolt to secure the first object to the second object.
1. A mounting assembly comprising:
a bolt head flange comprising an opening having a shank of a flange bolt passing through the opening and a bolt head of the flange bolt secured to the bolt head flange; said bolt head flange comprising a first side edge and a second side edge, said first side edge having a straight edge section oriented at an angle to a straight edge section of the second edge;
a bracket having a slot formed at an edge and having the shank of the flange bolt located in a gap of the slot; and
wherein the shank has a centerline defining an axis of rotation, wherein the second edge has first section with a first turning radius R 1 relative to the axis of rotation and a second section with a second turning radius R 2 relative to the axis of rotation, and wherein R 2 is greater than R 1 .
2.

3. The mounting assembly of claim 2 , wherein the first mounting section and the second mounting section have planar surfaces that are parallel to one another.
4. The mounting assembly of claim 3 , further comprising an intermediate section located between the first mounting section and the second mounting section, and wherein the intermediate section has a vertical wall surface or an inclined wall surface.
5. The mounting assembly of claim 1 , wherein the bolt head flange has a first section and a second section.
6. The mounting assembly of claim 5 , wherein the second section has a tab having a side edge and an adjoining edge located radially of the first side edge.
7. The mounting assembly of claim 5 , wherein a step is located between the first section and the second section.
8. The mounting assembly of claim 1 , further comprising a spacer having a bore and the shank is in the bore.
9. The mounting assembly of claim 8 , further comprising a washer with a plurality teeth engaging the shank and supporting the spacer and wherein a frame nut is threaded to the shank and supporting the washer and the spacer.
10. The mounting assembly of claim 8 , wherein the spacer has at least two different plate sections with different outer dimensions.
11. The mounting assembly of claim 1 , wherein the shank is located in an opening of a first object and the bott head flange is located in an opening of a second object to connect the first object to the second object.
12. The mounting assembly of claim 11 , wherein the first object is a running board having an elongated support member having two ends and a top wall for supporting a passenger.
13. The mounting assembly of claim 12 , further comprising a step attached to the elongated support member, the step having a surface for stepping on by a user and the surface is located below the elongated support member.
14. The mounting assembly of claim 11 , further comprising a spacer located between the first object and the second object, and wherein the shank projects through a bore of the spacer.
15. The mounting assembly of claim 14 , wherein the second edge contacts a surface of the second object.
16. The mounting assembly of claim 1 , wherein the bolt head of the flange bolt is welded to the bolt head flange.
17. A mounting assembly comprising:
a bolt head flange comprising an opening having a shank of a flange bolt passing through the opening and a bolt head of the flange bolt secured to the bolt head flange; said bolt head flange comprising a first side edge and a second side edge, said first side edge having a straight edge section oriented at an angle to a straight edge section of the second edge;
a bracket having a slot formed at an edge and having the shank of the flange bolt located in a gap of the slot;
a spacer located below, elevation-wise, the bracket and having the shank of the flange bolt passing through a bore of the spacer; and
wherein the shank has a centerline defining an axis of rotation, wherein the second edge has first section with a first turning radius R 1 relative to the axis of rotation and a second section with a second turning radius R 2 relative to the axis of rotation.
