those screws

[greystoke]

I'm seeing these a lot during disassembly, the screw head is kind of a rounded off rectangle. I don't have a screwdriver for these. Anyone know what they are called? I'd post a picture but couldn't find one.

Clutch screws

[greystoke]

ok..found them in google images. Now to find the bit that fits them. Thanks Shrek, by the way..how is donkey

[Russell Ashley]

Harbor Freight sells a set of bits that comes with three sizes of clutch head bits. It cost about $10.

[magicoolbus]

Very easy to find. Search Clutch head bit, found 30 or so of them. Here's one.

Harbor Freight has a 'security bit set' that has some in it too:

Enjoy.

Thank you gentlemen, I bought the set off ebay as it covers different sizes and will allow the extra leverage of a ratchet handle.

I have not had much luck removing clutch heads that have been in for any length of time. With the ratchet you can get good leverage but the cluth heads strip easily, so the extra leverage is lost on the stripping of the head. I have done well just grabbing onto the head with a pair of Vice gripps and unscrewing them that way (assuming you have enough room).

Good luck

I'm with Youngrodder on this one.
Spray any screw that's at all suspect with PB Blaster or your favorite rust penetrant before you try to remove it.
The last 50-odd years haven't eased dis-assembly on this stuff. Not on mine anyway.

[mr48chev]

Plenty of PB blaster or another good rust penetrate goes a long ways towards getting them out. Sprayed from the back side to get into the threads if you can reach the back side.

I've also found clutch head screwdrivers and bits at Ace hardware.

If there is room you can weld a nut to the head and use a socket to remove some of them .

[Russell Ashley]

Also, if they have been painted over it helps to take a pick and clean out the slot so that the bit gets a full bite. It keeps them from stripping out. I replaced most of mine with either hex or button head allen screws.

were ever i can i swap out with SS phillip...Sp

The first tool I ever bought of the SnapOn truck (MANY more to follow) in 1977-78 so I could properly remove the screws from my truck.

I don't know what problem would cause them to round out, they are pretty much one of the best ever for NOT rounding. If the screw is clean and it's the right size tip, it WILL turn that screw in my experience.

ironic, that was my first snap on purchase too, in 1970
my second was a blue point hammer impact to remove phillips head screws from yamaha motorcycle cases
and my 3rd was a clutch head bit to put on the impact driver to remove the fender bolts off my 58

for clutch head screws like what holds the trans cover on i use a flat head screwdriver
for fender bolts... torch or grinder

[msaintg]

I just ground an old standard screwdriver down to fit. worked fine.

[shrek55]

Amazingly took my 55 1st apart 2 years ago without penetrating oil and broke ONLY 1 bolt. Total frameoff

We're brothers from different mothers!

I still have all my Snap On purchases from all those years ago. This is one of the reasons I preach to buy good tools, not only do they last, I could sell them for MORE than I paid for them!

[Russell Ashley]

Not to hijack, but we need to start an "Old tools that we love" thread. I have lots of them.

welding nuts on works well!

As a last restort to remove a broken stud or a rounded off screw or bolt yep welding a nut to it has been done many times by this guy.

I used to use a regular screwdriver but after rounding several I just went ahead and bought the proper socket drivers.

I don't know what problem would cause them to round out

On this end of the country the answer usually looks like this:
