Questions about nut type;

[Olafur]

Ok I come across these to often and I am always in trouble dealing with them. Think pinion nuts etc

dont mind the small locking screws;

1) What do you call this type of nut.

2) Are they made to standard (many?) metric/sae?

3) Anyone seen socket sets for them including several sizes?

Name escapes me at the moment, but we have some fairly large (150mm is small, IIRC we have a 450mm) in metric thread pitch. We typally use a brash punch or chisel and hammer to get them moving

Sounds familiar. I am currently rebuilding the front differential from 300 hp Fendt farm tractor. Pinion nut is like this. Getting the old one off is the easy part. Assembling and testing the contact pattern several times and finally applying 500 Nm for the final torque is different story.

There is something, it will be interesting to see if the pinion nut shares dimensions with one listed by MMC.

Thanks!

You may find your answer at the site above. They are the only manufacture of that type of nut I know of.

See them for wheel bearings on heavy equipment all the time. Generaly use specail hub nut sockets.

Also pop up on diff output bearings and seals, usualy use a c- spanner for them.

looks like a locking ring on the AR-15 platform telescoping buttstock assembly. there are special wrenches that engage the notches to loosen/tighten them. have seen them on drillpresses as well...

Ive always called them a collar nut.
Generally a hook spanner works. They also make them with a square drive for torque applications.

who makes that one in the bottom pic? Have never seen one and now I must have it.

They are pretty common to retain the hubs on one ton and larger trucks. Sockets are readily available for those sizes anyway.

 

[HammerMechanic]

I've always referred to them as bearing lock nuts also.

I hate these types of nuts. They dominate the CNC tooling world for collets.

We usually don't use hook spanners, but specific spanners that fits better than hooks with more teeth engaging:

 

[Moose-LandTran]

We usually call them slotted nuts here in England.

Used on motorcycle triple clamps on the steering stem. Kawasaki call it a "nut"....That's it.

 

[Bagherra]

Similar to a UH-1 tail rotor retaining nut...

Also have something kinda like it on my GSXR...made my own socket to work it..
