Slotted nut for hold down threaded rods
A slotted nut has a body with a top surface, a bottom surface and a central axis. The body includes a base portion with first and second corners diagonally disposed from each other, the base portion including a flat surface. First arm portion and second arm portion extend from the first and second corners, respectively. The first and second arm portions are each C-shaped with respective first and second half-circle threaded openings including respective first and second centers disposed on the central axis. The first and second half-circle threaded openings face inwardly toward the central axis. The bottom surface is ramped from a third corner on the bottom surface toward the first arm portion to define a gap between the bottom surface below the first arm portion and a horizontal plane perpendicular to the central axis when the third corner is on the bottom surface.
1. A slotted nut, comprising:
a) a body including a top surface and a bottom surface, said body including a central axis;
b) said body including a base portion with first and second corners diagonally disposed from each other, said base portion including a flat surface;
c) first arm portion and second arm portion extending from said first and second corners, respectively;
d) said first arm portion is C-shaped with a first half-circle threaded opening including a first center on said central axis;
e) said second arm portion is C-shaped with a second half-circle threaded opening including a second center disposed on said central axis;
f) said first and second half-circle openings facing inwardly toward said central axis; and
g) said bottom surface is ramped from a third corner on said bottom surface toward said first arm portion to define a gap between said bottom surface below said first arm portion and a horizontal plane perpendicular to said central axis when said third corner is on said horizontal plane.
2. A slotted nut as in claim 1 , wherein said first and second arm portions each includes a portion extending axially in opposite directions from said respective first and second corners.
3. A slotted nut as in claim 2 , wherein said first and second arm portions are substantially triangular in elevational view.
4. A slotted nut as in claim 1 , wherein said top surface is ramped from a fourth corner on said top surface toward said second arm portion to define a gap between said top surface above said second arm portion and a horizontal plane perpendicular to said central axis.
5. A slotted nut as in claim 1 , wherein said body includes a hexagonal cross-section.
6. A slotted nut as in claim 1 , wherein said body is cylindrical.
7. A slotted nut as in claim 1 , wherein said body is spherical.
