Hi,
I know that Phillips head screws didn't come into existence in the teens, but when exactly did they arrive on the scene?
There's not one of the things in either of my T's, and I'll keep it that way, even the Speedster.

And what about dropped front axles for Speedsters?
Did they exist in the teens and 20's?
Does anyone know when someone first successfully dropped one a couple or more inches?

Thanks and Cheers,
Rob

Dropped axles were available as aftermarket items. Mercury produced them for instance. Read, "Model T in Speed and Sport"

Thanks for taking the time to answer gents. Its much appreciated........and my apologies for not taking the time to look it up on Wikipedia.
Cheers,
Rob

My 1951 Ford truck has Phillips head screws holding the window lifts to the doors.
The 51 cars also had a few crosshead screws.
I don’t know of any earlier than ‘51.

Phillips screws were first used on vehicles in the late thirties.

Thank Henry Philips...

I haven't seen any documentation of a dropped T front axle appearing prior to 1921.

From a maintenance standpoint Phillips head screws are easier to deal with when removing one that's seized or rusted up. That goes for any type of vehicle, equipment or etc.

They were an improvement over slot heads in that regard.

If they were readily avaliiable during the teens and twenties Ford would have used them.

That's a bit questionable, as Henry hated to pay anyone to use an idea. The Robertson screw was presented to him, and he turned it down, although the Canadian Ford used them a lot.
