Chrome Head Nuts Stripping

The other day I went to re-torque the head nuts and a few of them just would not tighten and I thought "O" no please don't tell me it stripped in the block. So I pull the nut off and found that the actual threads in the nut were stripped.

These nuts were purchased from vendor "M" has anyone else run into this problem?

Luckily I had the set that I took of originally and clean them up and reused them.

Tom: If you think that you have gotten a bad product from a vendor don't be afraid to state thier name. No use of beating around the bush.

I would contact the vendor and tell them of the problem and return them.

Any idea what the construction is between the two? Am wondering if the originals might have been stainless steel and the replacements a lower grade and apparently not very hardened ordinary chromed steel.

Tom, I'm guessing you're talking about acorn nuts and not just regular flat 7/16-20 nuts? A few years ago I bought a set of chrome acorns from one of the CCCA regions and they were poorly finished, lousy threads, etc., quite unsatisfactory. Since then I've been buying them in stainless from Tioga and they are a fine product. Another advantage of stainless is that the finish looks more like nickel plating which they should be anyway.

All thanks for the feedback.

I did not personally purchase them. The shop that did the engine work for me purchase them along with new studs from Max Merritt. The shop sent them for me to install.

No idea on the construction between the two.

The bad ones I have tossed already :( Probably should not have but I had no need for them and did not even think of calling Max.

This probably varied with years and models but I believe they were always standard equipment on the Twelves and optional in some fashion (factory or dealer) on Eights, Super Eights and other models thru 1939 at least. I often see them on later models thru 1954 and don't know if they were legitimately available for those models or not but they are not listed in the 48-54 parts book. I suspect they were also a popular dealer "dress up" option. They may also have been standard on the earlier Twin Sixes after the First Series (which did not have detachable cylinder heads).

They were not Packard approved accessories any of the 51-54 models. But are often incorrectly used for the bling factor. There is a company that makes faux ones that snap over your existing head bolts.

A previous owner of my '47 Custom replaced all the fasteners in the engine compartment with stainless steel when he did a mechanical restoration of the car from the clutch forward in the mid-80s. These nuts, bolts, screws, and washers add a nice but subdued enhancement to the appearance of the engine. The cylinder head stainless steel nuts (not acorn) and washers are a nice finishing touch without being flashy.
