I'm not sure what they are either. Back some time ago,
before I retired, we had 2 shapes of Phillips #2. one
was normal and the other was real narrow. I don't
remember the number designation for the narrow one but
I liked it because it sat deeper in the screw and I
thought it held better. That's kinda what yours sounds
If you would have Googled better, you would have found that some Phillips
tips have serrations and are made of harder metal and metal of different
metallurgy to resist chipping, stripping and schlipping.
But you knew that, right?
You know everything.
Not too bright either, I take it. You were talking
about not having newsgroups and I said bye to you
seeing as you were the one complaining. You sounded
like you were leaving. I'm not.
And yes, I do know quite a lot. As the saying goes,
I've probably forgot more than a lot of you will ever
The main company involved in replaceable screwdriver tips is Apex.
Apex is owned by Cooper industries.
Quotation from their site:
Apex offers a choice of three heat treat hardness levels in many
of our screwdriver bits to match the application. These heat
treats are specified by a letter suffix as follows:
X - Hardest heat treat in the industry
I - Intermediate hardness
R - Lowest hardness
Our experienced staff can help in selecting the best heat treat
for your particular application.
Apex bits & sockets last ten longer than most of our competition.
If you really want to know more:
Keep the whole world singing . . . .
According to this reference, the bits I've been snapping off are the
small-diameter "limited clearance" phillips bits. They are smaller diameter
apparently for no reason other than to allow access in restricted spaces.
Now I know...
Ain't USENET great?! (Chinese spam, 2-party bickering, and "Google Is The
Answer" 'bots, notwithstanding...)
