All about Screws

Hey, not what your thinking!

When a Phillips is not a Phillips.

What about those kind on the restroom dividers that you can tighten but not loosen??

Once it's screwed, it can't be unscrewed...

those are called "tamper resistant sex bolts"...really they are!

Just as long as you don't take a wide stance...

I remember back when I was a Snap-On dealer about the different screw drives I carried

and watching the different people look at before finally asking a question. Usually they

bought and it was because it wouldn't work with any other tool. Bill

for a guy that a bit obsessive about having the right tool for the job that article is seriously disturbing.

There are a few tools designed to remove the one-way screws. They are common tools for those that do toilet partition hardware.

you need to find something to do in the stalls besides looking at the hardware... and thinking about how to take it apart.

Being a patriotic Canadian, I aways use Robertson screws. There's much less slippage and they are easier to drive in with your drill.

I wonder if he ever had business cards made up with the following:

"Screws by Robertson--faster drilling, less slippage"

Hey Jeff,

Be careful what you say, it may piss off Crockett.

What an annoying link to follow having to click through so many pages to read the little content. I must take exception to his views about the regular, run of the mill slotted screw. He did however mention that mostly the problem is poorly designed drivers but failed to mention that with a correctly sized driver (one that has parallel sides or is hollow ground and closely fits the slot) tremondous force can be applied. In modest sizes enough that the fastener itself will either strip or break before the head strips. Alas there is a reason that gunsmiths still use slotted screws.

The critical part is the driver must fit the screw slot in width and thickness and have parallel bearing edges.

Hey Mark,

Bet you still got a set of Chapman Driver's. I had mine about 30 years now and wont touch a firearm with anything else.

Sure do and as I've broken a few I've replaced them with Brownells fixed blade. At least one of these I even ground to exactly fit my Ruger Blackhawk.

Working in the shop today I looked at the 'Phillips' bit I was using and discovered I had standardized on a ARC 2 bit. Found them in the BORG some years ago and they work very well in standard Phillips screws.
