Anyone know what length and thread size the small screw that locks the steering cover on is?
It's a 6-32 roundhead slotted screw, long enough to securely stop the steering cover from turning - maybe 3/8" - 1/2" long thread?
Usually you have to turn the head down slightly to match the original size.
That tiny screw has always been questioned! What is it from 1920's:
Thanks Dan, I overestimated the length..
Uh, discrepancy in the old articles. One says 9/32" long, which is a negligible 1/32" over a quarter inch, the other says 9/16" which is a sixteenth longer than half. I'm pretty sure the "nine thirty-seconds" is an error.
Good catch, the reply to question is incorrect on "9-16" should be 9/32"
Here's an original.
April 1st 1919 Parts Book:
3505 Steering gear cover screw No. 6, 32 x 9/32"
Dan, thanks for clearing that up ! I never gave much thought to the importance of that little screw !! Still, the report of the feller who wrecked his T because the cover came all the way off, he wasn't paying much attention - I'm pretty sure there would be grease on your knees before the cover came entirely off, and you'd think the steering would start to feel strange ?
Ace hardware has this size screw. Almost identical.
This is a great post, one of the reasons I read this forum every day! Tomorrow I will go find one of those screws so I dont forget it on my restoration. Thanks guys
For my '25, I bought a stainless screw, and re-contoured the head to look like an original.
Stainless fasteners are great replacements for any that were nickel plated originally.
Larry, Rich, and I think alike.
My favorite stainless steel application was oval head woodscrews to attach the nickel plated common sense fasteners. The stainless steel screws look great and won't twist in two like the nickel plated brass screws will.

Very important screw! I had an uncle who had the steering wheel come off a Model T while going around a corner on the way to Lake Arrowhead in the San Bernardino Mts. I don't know what year it happened. He broke his nose and by the time he got to a doctor, he was told by the doctor that he would have to break it again to straighten it so my uncle's nose went to one side the rest of his life. Fortunately that was the only injury.
That's a pretty cool story Norm, maybe we should start a thread about Model T injury stories
This screw was not fitted to all of the late steering gear covers. I can confirm they are round head 6-32 UNC, having worked with the original factory drawing for this part. . A half inch screw works fine, as the screw goes down into a half hole in the housing. When fitting a new cover, you will likely need to redrill the lower hole, so it can go all the way down. This would be a Dremel moto tool sort of job, as there is not a good way to hold a twist drill to do it.
I never fitted the screw on mine at all. Seems to stay put a year later, but I check it once in a while.
Some people claim that I have a screw loose.
I think it is a compliment.
Fred, I've always looked at it as if I just had one screw loose, I was doing pretty danged good!!!. Dave
That screw hole was not drilled in a NOS cover, but was left to the purchaser. Originally from the factory they were at 12 O'clock, but on my '25 I had to relocate the screw to 7 O'clock to get it tight.
I can`t find that screw or any evidence of one on my `25 Touring----Am I missing something? Paul
Here is a picture of two, yep, two screws missing..
Paul, here is picture of mine on my 1923 Touring.
