For me, I have a thing for clutch head screws! I don't care if they might be inferior or a pain sometimes. They are unique and iconic to these old vehicles. I am always looking for places to use them where they don't belong, like inner fender-to-fender, bed front-to-bedsides, top radiator pan. They're just TOO COOL! My early 49 AD has them to hold on the VIN plate. They are real small and possibly original, as the screws are much smaller than the holes for the rivets that I'm used to seeing used to attach VIN plates.

There is nothing inferior about clutch-head screws. They have superior torque/grab characteristics over slotted-head and Phillips-head screws.

People either do not have the correct drivers, or they have the mistaken notion that removing rusted clutch-head screws is more difficult than removing rusted slotted/Phillips screws. Removing any rusted screw is difficult.

Carl, you might be interested in this Jim Carter article on clutch head screws on ID plates through 1950.

McMaster Carr or Fastenal have them but make sure you order the right kind. There are 2 types of Clutch head screws...

I actually looked on McMaster and couldn't find anything. This surprised me, as they have EVERYTHING! I found the bits, but no screws. If they're there I missed them somehow.

As Grigg pointed out a while ago, McMaster-Carr has the bits at reasonable prices.

I do not see clutch-head bolts/screws (either type) in the McMaster-Carr or Fastenal catalogs. Maybe CASO will tell us how to search for them?

Truckolet,
- Did you look at the sources at the link that Lonnie posted, above?
- Did you check out the Restoration Specialties catalog? Page 182?

To work with these fasteners you need the proper drivers or bits and before you attempt to mess with an old clutch head fastener, you need to clean out the hole. The sides of the hour-glass shaped hole are straight, so to get the driver in there all the way, you need to clean it out with a sharp awl or other tool. Get all that rust, grease and dirt out first. If done properly, you will either remove the fastener or snap the head off the fastener, before it slips out. What more could you ask?

If originality is not important then use whatever is handy. I would go with a torx, square hole or other straight sided fastener before I would use a slotted head screw or bolt. I was trying to retain an original appearance to my truck so I bead blasted and reused all the fasteners that were not damaged upon removal.



It takes many years of carefully removing the original clutch head hardware to come up with enough extras to get you through an original restoration.
