Pipe hanger with anti-vibration washer

1. A pipe hanger comprising:

a suspension member configured to engage a pipe, the suspension member comprising a side edge and defining a hole through the suspension member;

a threaded rod extending through the hole and defining a distal rod end;

a nut threaded on the threaded rod, the nut defining a circumferential side; and

an anti-vibration washer disposed on the threaded rod between the suspension member and the nut, the anti-vibration washer comprising a body, an edge tab, and a nut tab;

wherein:

at least a portion of the edge tab is bent to fold over the side edge of the suspension member;

the nut tab is bent to fold over the circumferential side of the nut;

a distal portion of the nut tab is bent to fold over the distal rod end;

the distal portion of the nut tab defines a tab end;

the nut tab defines a tab opening therethrough to facilitate bending the nut tab relative to the body;

the nut tab defines a first tab leg and a second tab leg, each of the first and second tab legs extending from the body to the tab end;

the tab opening is defined between the first and second tab legs; and

the tab opening defines a first relief notch formed between the first tab leg and the body and a second relief notch formed between the second tab leg and the body.

2. The pipe hanger of claim 1 , wherein the edge tab defines a first tab section and a second tab section, the second tab section bent about 90° relative to the first tab section to fold the second tab section over the side edge of the suspension member.

3. The pipe hanger of claim 2 , wherein:

the body is disposed between the edge tab and the nut tab;

the first tab section of the edge tab and a proximal portion of the nut tab extend from the body; and

the first tab section of the edge tab is substantially coplanar with the body.

4. The pipe hanger of claim 3 , wherein:

the edge tab is a first edge tab;

the anti-vibration washer further comprises a second edge tab parallel to the first edge tab;

a slot is defined between the first edge tab and the second edge tab, the slot defining an open end and a closed end; and

the threaded rod extends through the slot.

5. The pipe hanger of claim 3 , wherein:

the proximal portion of the nut tab is bent about 90° relative to the body to fold over the circumferential side of the nut;

the distal portion of the nut tab is bent about 90° relative to the proximal portion to fold over the distal rod end; and

the tab end of the distal portion of the nut tab is distal to the body of the anti-vibration washer.

6. The pipe hanger of claim 1 , wherein:

each of the first and second tab legs defines a first leg section adjacent to the body, a second leg section adjacent to the tab end, and a bend line between the first and second leg sections;

the distal portion of the nut tab is bent relative to proximal portions of the nut tab at the bend lines;

the proximal portions comprise the first leg section of the first tab leg and the first leg section of the second tab leg; and

the distal portion comprises the second leg section of the first tab leg and the second leg section of the second tab leg.
