More than you probably have used, or seen

 

 

 

...and probably more than we need.

Good many of those I have seen. But at work on cars and heavy trucks.  Or at the Hanger at Southwest.  

The clutch is about the only one that the the drive bit never spun in the socket.

Thanks!

I had to work on a camper back in the '80s.  It had clutch head screws and I had to buy a whole assortment of drivers to get one.  Now, they seem to moved to square drive (of which I have lots).

 

We used to get a lot of cam-out on screws on the theater set construction.  People would just go crazy.  I convinced the manager to go to Torx and most of that has stopped, except for one guy last weekend that both messed up the screw and messed up the driver.  As soon as you make something fool-proof, a bigger fool comes along.

 

Probably the worst (besides the slotted, IMO) is the combo drives.  None of them seem to work well.  I've had a few customers mess up the square+phillips and I pull out my square driver and get it out and they look in amazement.

my favorite story was from many years ago, a crew was assembling some steel studs for an interior space.  and using little green screws to hold the parts together.  one big guy, worked all day, only to discover, at the end of the day, that his screw gun had been set to "counter clockwise" all day.  hey, the screws went in, didn't they.

 

work harder, not smarter.....

Ain't THAT the truth!

If you really want an education about screws, metals, coatings, threads, shafts and usages, order a McFeely catalogue.  It is an education.  I keep an old one to look at when I get ready to order.

I may print that one out and hang it in the shop.

I don't need to hang that sign, Artie. A mirror will suffice.

That'll insure you get it backwards.
