Hello again
My search today is for a steering wheel retaining nut. With all the early Single Sixes that have been dismantled there must be someone somewhere with a spare. Having discussed making one there seem to be a number of obstacles. The obsolete thread size and pitch is just one. (13/16 X 20 tpi) also the unusual size hex barstock seems to be a problem. It seems the only way I can get one made is to remove the steering box and completely dismantle it in order to have a sample of the male thread to take to my machine shop. Something I would sooner avoid if possible.

If you can't find an original nut, Online Metalsonlinemetals.com/merchant.cfm?pid=19782& ... howunits=inches&id=1341&top_cat=197 carries cold roll hex barstock in 1 7/16" and Victor Machineryvictornet.com/alphabetic/Taps-Special-Pitch-17-32-to-1-1-8/212.html has the special thread 13/16 x 20 tap.

I have bought from both places many times. Unknown is whether cold roll is suitable material for that nut or if either company ships overseas.

Bernie,

Just trying to expand the range of nut availability. No, that's not me, though it could be!

Looking in the Parts Lists and Manuals available here on PackardInfo, in the '25 Six Parts List P/N 127012 Steering Post Upper End Nut is shown as fitting 126/133/226/233/326/337. Then P/N 127012 is also shown in the 7-9th Series Parts List and in the 33-36 Eight Parts List as fitting all models.

Hope this helps.

Bernie,

You may want to look at a Doorman Axle / Spindle nut P/N 615-074.

It has a 13/16-20 thread, and if it has enough height it could be machined to match what you need.

I think the nut above will probably do the job nicely however if you want to keep it original you should have a new nut made. If the machine shop you contacted says they can't produce the nut without the male counterpart then they should be avoided. Any machinist worth his salt will make their own male thread gauge first. It's not difficult to chuck up a piece of bar stock and cut the male version of those threads. Once the male set has been made and checked with wires then the female threads can be cut using the male threads as a gauge. There is no need to remove your steering column, that's a ridiculous request. Cutting the hexagon is also not a difficult task and is probably cheaper than buying a piece of hex stock. If you asked for a thousand bolts you'd start with hex stock but for a single bolt it's not cost effective. Expect to pay for about an hour and a half labor for your nut which is probably around $120.
