In our line of work, fastener systems appear particularity fragile and accident prone. We’ve seen plenty of broken or damaged clevises come into our shop – and the men and women who bring them in often have no problem finding clevis pens. It’s sourcing a new clevis that seems to be the issue. What do you do when one breaks? Well, your first course of action should be to acquire as much information as possible about the broken clevis. Take a look at this drawing.
Here are some things you should make sure to mark down:
The Clevis Number
This number usually reflects the full diameter of the forged clevis, so it’s useful when searching for a replacement. Perhaps most useful. It is marked by the “D” on the image above.
You should identify the finish of the clevis as black or hot-tipped galvanized. If a hot-tipped galvanized rod is involved, the clevis will have to be tapped “Oversized” to accept the threads of the rod.
The Diameter of the Tap
This is the diameter of the side opposite The Clevis Number. It is internally threaded and is the part of the clevis that the threaded rod will meet. It is marked by a “W” on this particular drawing. The tap should be ordered oversized when dealing with galvanized clevises – this allows it to accommodate galvanized rods accordingly.
Hop over to this site for more in-depth information on what specifications you should write down and how you should write it down.
For now, let’s move on to what you can do about your clevis issue. As far as we are concerned, you have two options – order a new clevis and wait for it to ship to you (most part stores do not carry them in store) or request to have one made in our shop. We can help you get your part within a few days. And, in extreme conditions, we can have your part to you the next day.
If you simply have to get back to work ASAP, don’t hesitate to come to us with your part needs. We’ll look out for you – as best we can.
