What do you call a castled washer
What do you call a castled washer
I want to make bushing blocks, for threaded rods. Then secure rod with nuts that won't backoff. Looking at buying somthing to make a keyway at the end of the threaded rod and use a castle washer to secure nut.
Thank you for any advice.

Not sure what a castle washer is, but to secure a castle nut, all you need is a hole through the threaded rod and a cotter pin.
To drill the hole, I would drill a hole through a plain nut to use as a bushing, Then, thread the nut on, centered on where you want the hole, lock it with another nut, and drill.
You might want to run a die over the threaded rod after drilling to clean up the threads.

Ah maybe that is what he means. I couldn't figure out what a "castle washer"Peter. wrote:Do you mean a tab washer? They use a slot in the shaft and external tabs to lock a nut.
was. Never heard or saw the term.
I just made an axle and had to do the two cotter holes for the castle nuts.
Actually the term is (at least use to be) Castleated .

Do you mean the type of washer used with a nocknut (like the ones at http://www.whittet-higgins.com )?
You could also consider Flexloc type nuts which are similar to nylon inserted nuts but the lock is MUCH stronger and they're re-usable.

There's an excellent book that discusses this in considerable detail. It's
Carroll Smith's book "Nuts, Bolts, Fasteners, and Plumbing" and I strongly
reccomend it.
Among other subjects, he talks about how to lock fasteners in an
absolute, positive way. The kind of way to do it, if a life depends on it,
in racing and in aviation.
The short story is, split washers are no good. Wave washers are no
good. Tab washers into a slot are no good. Prevailing torque nuts
are not bad. Nyloc nuts are not bad. Cotter pins through a castle nut
are pretty good. Safety wire is very good. Thread locking compounds
used correctly, are very good.
But the book has a huge amount of other information involving threads,
stress concentration, fastener types, and lots more. It's inexpensive
and well worth the read.

According to Loctite®, the only thing that works is Loctite®. (Imagine that!)
The world was turning a long time before they started making products.
I've yet to see a properly installed lock tab fail under it's recommended use/conditions.
I prefer the tabs, as I can visually inspect them for security. If someone has replaced the tabs with Loctite® I have no way to inspect the security other than to loosen and re-install the fastener to determine it's securing method.
For that reason, I don't use it.
