Technical What kind of screw is this....

I run across these from time to time, and can get by with making a small tip to get them out, but it would be nice to have a nice screwdriver to get these out. They always seem to strip when I try a homemade tip.....

 

I think they are called clutch head screw.

 

What he said^^^^^^^^^^^^^^^^^^^^^^!!!!!!!!!!!!!!!!!!!

 

Amazon has everything........

Public restroom stall screws.

 

Oh, come on ... everybody calls 'em $&%^&*(*^&*er screws ....
Or Chevrolet screws. Apex brand was the best set of 1/4'' drivers

 

They are also available at Ace Hardware. HRP

 

Lots of old canned ham campers used them also.

 

Awesome thanks for the answers! I just didn't know what they were called.

 

Yep, clutch head. Had to buy a set of drivers when I had my 56 Chevy P/U.
5 or 6 sizes.

 

Try getting them out when they're rusted in, I've drilled out my fair share and yes i have the correct screw drivers and bits to get them out.

 

Should be called PITA screws

 

Yup. They shut me down today. Can't find my bits.

 

My 62 Nova used them to secure the horn ring in my column. I found a medium Phillips head screw driver did the trick.

 

get the correct driver and use a mapp torch to heat them use a couple times to help remove them. most of all be patient and if the heat doesn't work use a mix of 50/50 acetone and old ATF! nothing better!

 

When I bought my '51 GMC the po gave me a handful of clutch head screwdrivers. Very thoughtful of him-

Now if I just had the original door latches instead of the chinese tinfoil bullshit he replaced them with I wouldn't worry about falling on the ground every corner..

Use "needle nose vise grip" Pliers to get first one out to take to "tool store".
AFTER you get proper tool, as you twist anti-clockwise direction, tap with hammer on end of handle, to remove.
chevy step vans interiors are assembled with them.

 

About 15 years ago, I bought a selection of "odd" bits in a plastic case. I think there are 4 rows of about 20 bits each. It has just about every size of everything. For example, it has all of the sizes of Torx bits and all the same sizes of Torx bits with a hole in the center. (It seems there are Security Torx screws that have a pin in the center of the head to prevent the use of regular Torx bits.) Anyway, they have come in real handy for many things over the years, and since they are all in a single case, I can always find what I need. I can't imaging having 40 or so specialized screwdrivers cluttering up a few drawers someplace.

 

GM used a lot of them in the late 50s early 60s.

 

Here is a slightly OT tip...try not to use the tamper-proof, or security type torx bits on torx fasteners without the tamper-proof pin. The bits are pretty brittle, and will break easily without the pin in the center to support the hole in the bit.
