Default In search of Stainless Steel hardware.

Specifically the bolts that hold the rear end banjo to axle housings. Gennie Ford bolts don't have treads running all the way to the head of the bolt. This is to reduce leakage past the bolts.

It's best to use original bolts.

Chris, I have found the issue with bolts weeping is generally caused by a cumulation of minor issues. Most of the time when a file is drawn around the differential housing bolt holes, you will find that threads have been pulled due to overtightening which causes the gasket to not seal. Next is that most gasket surfaces are not flat, which again causes the gasket to not seal. When the housing is trued in a lathe, this is seen, -and thus corrected.

The third issue is that Ford prescribed for a special tolerance fastener in this location. Roy Nacewicz used to manufacture this fastener however in a pinch, when a thread sealant such as Permatex or one of Loctite's sealant is used correctly, the leakage is gone. It is my opinion that the fastener you a suggesting will not prevent lube from weeping/leaking.

Roy Nacewicz Enterprises exists (http://fordscript.com/) but I see Roy himself is recently passed. https://molnarfuneralhome.com/tribut.../obituary.html

No word on whether the Enterprise will continue.

+1 on the tighter thread class fastener at this location. Big box bolts, even Class 8 don't cut it.

Joe, Marlana has told close sources that she is not interested in continuing.

Unless you put lock washers under the bolt head, there should be enough sealing between them and the axle housing that even a small amount of sealer should take care of leaks. Also as was said above, these are not standard fine thread. I use the white thread lock on the bolts and anaerobic sealer between the gaskets and housing.

may be over kill but that is how I do it.

Hopefully you didn't chase the holes........................dental floss wrapped around the threads helps I've been told.

I am thinking that modern bolts, stainless or not, with the wrong thread pitch is going to have more issue with oil migrating along the thread.

It's your car do as you like.

When I read this, I was surprised ! Stainless Steel is noncorrosive, but is it strong enough to be torqued on a suspension part. SS is not the strongest of metals and considering all the torquing and twisting that is done to these bolts (5/16 X 18 ? ) SS is about the last alloy i'd want holding this component together. Rear bolts are not really subject to a lot of corrosion anyway.

Strength depends on the alloy.

Bill,

If any of us can wake up dead, I'm betting you'll do it!

Is she willing to sell the assets to someone that will continue the manufacture of the stock?

Many stainless bolts sold were visual "duplicates" of the larger than usual USS fasteners.

There is of course a hue and cry for "Ford Production Fasteners" which differ from common fasteners from most of the big-box/drawer outlets.

I just received "correct" valve chamber cover bolting from Snyders for which I paid a small extra for - rather than buy the "common" bolts they also sell.

I mean, if you're going to do it - one does it "right?"

(Yea I know - define "right." Some don't/won't re-use original fasteners.)

Methinks we're going to miss Roy Nacewicz.

For those of us who were close personal friends with Roy, yes there is a large void left with his passing. For others, it really is just more of an inconvenience.

I am already setting up for manufacturing the fender and cowl welting. I have also found the machining company that was making some of the fasteners, but based on the direction I think the hobby is going, I really don't see much of a ROI. What I have found is that many of the items he sold were already being manufactured and he just knew where to obtain it. Additionally, those places typically have a 1,000 piece minimum quantity order, so the average restorer is not going to buy 1,000 bolts to get the 4 they need for their project. For Roy, he might sell 15-20 sets of those type bolts a year. To invest in the quantity of each item needed and the cash outlay would be extreme, -and unfortunately the trend is most Model-A restorers don't see the value in using a correct fastener versus just using a Tractor Supply type bolt or nut. To keep this comment on-topic, to have the correct size & shape bolt for the rear end housing was going to be about $ .25 a piece with a limited quantity run. Look at how much a consumer would have in purchasing & freight in buying a set for their project. Look at how much investment the vendor is going to have tied up in product before they are all sold. Roy was a retired guy who loved to talk, and so his cottage industry gave the opportunity to do what he liked to do. He did not do it for the money.
