New screw head type

Page 2 of 2  
It's not that new... I got a few boxes of those things with the "Deck Master" kit I bought back in 2001.
They require a special and very hard to find bit...
For the life of me, I can't imagine the "why" on this design.

To sell special and very hard to find bits of course.

The why is easy. Phillips screws require a lot more inward pressure to prevent cam out and the Robertson screw square head tends to snap off bits.
The screws were designed to keep the production level up. If the ability to do the job is as good as they claim, then the market will dictate that the design survives.
The price of the bits or the drivers is cheaper if you consider how fast one scraps Phillips bits.

If you are not part of the solution, you are not dissolved in the solvent.

Really? I've never snapped off a Robertson bit or screw head, and I've driven screws that took both hands to resist the torque of the power driver.
I can only imagine that you were either screwing into something really hard with an impact driver (in which case it should be pre-drilled), or else the bit had a manufacturing flaw.

Actually proper use of an impact drive is actually easier on the head of a screw. Trying to drive a screw farther than it should be driven with an impact driver can cause a break as with any type driver. 3 weeks ago I built an entire deck cover using the less than ideal common Deck Screws and used an impact driver to drive the majority of that 5 lb. box of those 3" screws I broke no screws but did break 2 bit drivers because of an improper union of the screw and bit. This happened on the same screw. I have broken several square head screws with a 9.6 volt drill usually because the screw was too small for the application or the wood was too hard for the size screw.

It's not cheap if you have to drive to the next town and dig around in the back room of the hardware store to find one. Though I will agree that Phillips is a sort of crappy screw head.

I much prefer a torx--you can get the drivers at Sears or Home Depot or any auto parts store, and Lox doesn't look to be any kind of major improvement over it. Sure, that business about locking onto the bit sounds good, but a decent magnetic driver handles that with just about any screw except solid brass, bronze, or some types of stainless.

Actually if you buy quality screws a square drive bit and screw lock together with out the need of a magnet driver. I very often have to "Yank" on the drill to get the bit and screw to part. This is not to say that Torx is any better or worse but that if the Lox holds the bit better than a good square drive screw it may be more of a nuisance to use.

Yes, I know this. Torx does not lock together reliably. Hence the magnetic driver. I tried square drive. If I had not used Torx first I might have liked square drive, but using "good" drivers and "good" screws (I'm assuming that what McFeelys sells is "good") I found that I was getting results only marginally better than Phillips.

YES, McFeeleys sells good screws. Don't mistake their screws for what you find in the Borg or misfitting Deck Screws. Typically you can plug the screw on to the bit and the swing the drill around, up, down, backwards, forward, in, out, and the screw stays put. Very handy in tight situations or when you have to stretch to reach something and you can only use one hand to start and drive the screw. Then after driving the screw you typically have to give the drill a yank or wiggle to part he screw and bit. Removing square drive screws can be a bit of a problem at times. The screw is stuck on the bit and hotter than a fire cracker after removing it. Sometimes tapping the side of the screw is not enough to get it to drop off of the bit.
I used the Torx screws in the automotive business and that screw really improved the replacement of sealed beams not to mention all the other parts. With the sealed beams being spring loaded the old Philips head screws holding the retaining ring were a PIA to remove.

Yeah- torx are good, too.

To make carpenters swear (even more), I'd imagine.
When I put up a deck for my parents this summer, all the deck screws were combo drives (like a phillips with a square head in the middle.) They work great- but one bit comes in a 5-lb box. After losing a couple, I was down to one, and went back to buy some bits- Surprise! They don't carry them. You have to buy another box of screws to get the drivers. So, they ended up being funny looking #2 squareheads for the rest of the project.
Looks like these Lox ones are even worse- no fudging there and using something that is almost as good, you *have* to use the proprietary bit.
Even if they're awesome, I think I'll pass- at least until they start selling the bits in the bins at the checkout of the hardware store with the phillips and squareheads.

Proprietary $ucks for the most part ... and to do it with screw bits, so that you can only buy the bits with the screws, is so much the "numb nut corporate mentality" that it hurts.
... "when will they every learn?".
