Hi Everybody,

 

I need to get some replacement set screws for a few Riggen and AJ's aluminum wheels. I'm guessing that the correct size/thread is .035 4-40 but I'm not sure.

 

Does anybody know the correct size and thread for these wheels?

4-40, one item that hasn't changed through the years.

Are you guys saying that a common Parma set screw (Par-555) will do the trick?

Hi Scott,

 

I'm not familiar with Parma's numbers but the same set screws that fit today's new wheels also fit all the vintage wheels. Same screws that are used in Parma gears.

 

Today's set screws are sometimes short or hollow to save weight but all wheels have always been 4-40.

HO wheels used either 2-56 or 0-80 if I recall.

SOME vintage (1/32 & 1/24)  are different...maybe 4-40 or 5-40 like the old axles...or even 3-48.

***MORE INFORMATION ADDED TO THIS ARTICLE ON 8/9/15***

These techniques apply to all scales, so read through it even though I'll be specific about the hard to do HO sizes, as this was posted in the Vintage HO Cars Forum. The proper thread size for the set screws on the HO scale wheels should be 0-80, same as the axles and jamb nuts. The very small hex wrench size is .028", so buy a couple of good quality ones. I like to use the vintage aj's wheel sets on my Aurora T-Jet runners and racers. They look great with the aluminum wheels all polished up, right? Many times the set screw is seized (bi-metal reaction from being unused for decades) in the aluminum wheel. Patience, along with lots of applications of WD-40 and the good quality hex wrench are usually required! If you have wheels without any tires on them, heat can also be carefully applied, if necessary. After you've got the set screws out, hold them with the wrench and carefully clean them up with a fine wire brush. Be sure to work over a shop rag or tray that will catch the screws should you drop them (it happens). Add some oil to the screw and wheel threads and see if you can easily thread them back into the wheels, WITHOUT forcing them. If needed, use an 0-80 tap to clean up the threads in the wheel (including the thread on type), working carefully and with oil, because aluminum is soft metal. An 0-80 die is also handy for chasing any rough threads on the steel axles of the thread on type wheel and tire sets, again working slowly with oil on the axle threads. Both the tap and die are good additions to any HO racer's tool box. When re-installing the set screws, I always put some good quality oil in the threads of the wheel and the set screw itself. Excess oil can always be wiped away before racing, and this usually prevents the two metals from seizing again. Check the set screw axles for any burrs, clean them up with fine emery cloth. A light drop of oil on the axle when re-installing the wheel (whether set screw or thread on type) is always a good idea. If jamb nuts are being used, be sure the thread in those are clean as well. Now, it's time to clean everything up and polish those wheels! Use Simichrome or similar metal polish with a Q-Tip. As I said at the top, the same techniques can be applied to the larger scale wheel sets, just use the appropriate size tools and hardware.

Thanks for reading, I hope this helps you guys out. Enjoy! -- Ernie :>)

I have a few pairs of these HO setscrew wheels and axles (unused). If anyone is interested I will post them for sale in the swap shop.

There are many HO wheels made with #2-56 but I have also seen #0-80 & #4-40. Take your pick. (I have never seen #3-48 used as a set screw for HO but it's always possible.)
