Splain to me Lucy about clutch head screwdrivers ?
« on: May 29, 2015, 03:40:55 PM »
I know about clutch head screwdrivers used on GM cars and trucks in the 40s and 50s. I have owned many old Chevies with them. Recently i have bought several screwdrivers that somebody called the new style clutch head screwdrivers. They are like a plain everyday driver except they have a straight blade with a round post in the middle. What is the story about them ?

If I under stand correctly your talking about a tamper resistant screw. Could that be it?

It has a blade like a straight tip screwdriver that one would use to drive wood screws, but in the middle of the blade it has a round section. i read that is the type of screwdriver that is made for clutch head screws. My grand daughter is not here right now or i would have her post a picture.

These are called tamper-resistant TORX.


Clutch type screws have a drive hole that looks sort of like an hourglass. These are the bits for them.

There are two types of clutch head type A and type G. You sound like you are describing type A.

I have a couple of type A drivers and have never had a need to use them.  Then again I've never seen a fastener with a type A head on it that I can remember.

After a lot of years I am firmly convinced there are more types of security screws than there are security screwdrivers.  I have at least 3 "COMPLETE" according to the salesman, sets of security screwdrivers, and still find screws I don't have a driver for.

Hang in there Nola, I got a number of years on you and I still learn new tings almost every day.

Check this site out... everything you ever wanted to know about screw drive bits.  I opened the page at the little known "Fearson" bit, not to be confused with Philips.

I found this old thread by doing a search on clutch head drivers. I’ve had this Apex driver for a long time and now I know a little more about it. Thanks, Bill!
