Karl, after we talked about different types of fasteners a while back, I de
cided to give SPAX a try. You're right... I like them! They are a graded
fastener, the have a thinner body than the screws I was using, and they are
easier to drive.
I like the Torx drive, but the driver they supply seems soft. The screw hea
ds don't seem too deep, so you have to be at 90 degrees to have solid, no s
lip drive. I am used to the hundreds of thousands of Phillips and square d
rive screws I have driven, and find the fact I have to be right on top of t
he screw to drive it annoying as hell. In a tight space with a long extens
ion to reach, I can usually drive a Phillips head about 15 degrees of so of
f parallel from the head, not so with the SPAX screws and the supplied bit.
Since I do a lot of maintenance and repairs, this is pretty important to
It was highlighted last week when I had the kick off a long bath vanity tha
t was caulked/marble topped/mirrored into place and I couldn't get to the c
arcass base runners any other way than laying on my stomach and running my
impact driver with a long extension with a screw on it as far back as I cou
ld reach. When the screw would bite and find its way into the wood, it wou
ld change the drive angle and the bit would slip from the screw. After goo
fing with it (laying on my stomach getting my arms torn up by the tack stri
p) for about 30 minutes I gave up and got my Phillips screws out and finish
ed the job quickly.
This isn't the first time I have had drive problems with the screws, so I a
m wondering what the problem might be. When I am over the screw, they driv
e very well and their aggressive threads make it quick. I like they fact th
at hey are graded for use, and the others I use aren't.
So is it the bit, the screws, or both? Or do I need to confine my use of th
ese to more perfect conditions?
Next, how water/moisture resistant are these screws? I am getting ready to
install a lot of grab bars in a house, and a few will be in the house bathr
ooms. I dont' want to see the bars outside the shower/bath rust, so I am w
ary. I would like to have a screw that I didn't have to drill a pilot hole
to install, but I would like to have rust resistance even more.
Any thoughts would certainly be appreciated!

Not saying to use deck screws but, I see that Spax cabinet screws use a
"T-Star Drive". Is that the same as Torx? I know that there is a drive
that looks like a torx but not exactly, like square drive and Robertson
drive. Could you possibly be using the wrong bit? I know you said you
used the one that came with it.
And FWIW I looked at HD Spax driver bits. They are not the same as
Torx. Oddly they have an extension on the end that prevents the splines
on the bit to reach the bottom of the screw. Torx bit don't have that
Maybe an actual Torx bit would work better.

I hope it isn't the wrong bit! It is the one that came in the box in a smal

that didn't fit quality screws well.
Crap, Leon. I never noticed that little nib on the end of the bit. WTF? A
quick look at the bit in the box I was using indeed had the nib as shown i
n the picture. On the box though, it simply describes it as a Torx bit.
I didn't think to use a regular Torx bit. Probably because I have used the
se screws for the last 10+ years:
These screws are supposed to be #2 Phillips, but I found out the hard way t
hat they are slightly larger, and the #2 bit THEY supply actually fits perf
ectly. Conversely, it almost doesn't work at all on a regular #2 Phillips.
So when a manufacturer supplies a bit with their fasteners, I don't look
left or right, but use the one they supply.
I like those Grip Right screws as I have never had one bit of problems with
them, ever. Very rarely do they cam out, I have never broken a head or th
e shaft when driving, and never had one fail. I hang cabinets with them, s
crew cab stiles together with them, make repairs with them, fix decks with
them, and on a on. However, a pilot hole and a head sink is a must, so aft
er talking with Karl he assured me that those two steps were almost never r
equired. He was right of course, and the Spax have turned out to be a time
saver and a half. I guess I will try a regular Torx bit and let you know
how it turns out.
They have a new brand of screws on a kiosk at one of the HDs I go in the mo
st, and they were supposed to be direct competitors to both Grip Rite and S
pax. They are really aggressive in their threads and have a deep cut along
the side of the shaft with a sharp point that means no drilling. Could be
I use square drive 99% of the time, either from an assortment of Kreg
Screws or from McFeeleys. If I am in need of a lot of long 3" screws, like
for 2x4 stuff I use the torx head tan coated deck screws. I have found
that they are not nearly as tough or stiff as the non coated McFeeley
screws. A few years ago I bought a box of 3-4 hundred of the torx coated
deck screws to build shelving in my store room they worked great. I used
the same batch to build a 4' x 8 ' porch on the front of the store room.
I used treated 2x4's and the 5/4, 1x6 treated deck boards. I have been
very disappointed in both the deck boards and or the deck screws. During
the summers if the deck boards get wet they bow and actually break those
coated deck screws. Oddly those deck screws are doing fine inside the shed
but they are breaking on the outside. I have had to replace 5-6 in the
last 3 years.
I'll have to keep an eye out for that new brand I'd screw.
According to Spax, they use a "T-Star Plus" head. T-Star Plus
is apparently the same as "Torx Plus". According to Texron
(who developed Torx) the Torx Plus bit allows more torque. It's
also a tad larger than standard Torx, so a regular Torx bit will
fit a Torx Plus screw, but poorly.
This seems to me to be an unfortunate attempt by Texron to
confuse the market. Now we have two slightly different Torx
drivers that sort of work but aren't really compatible. Much
like the dozen different variations on Phillips (and the
tendency of cheap drivers to not exactly match any of the
FWIW, I have always heard that "square drive" and "Robertson"
are exactly the same. The square drive name is used in the US
because of some legal thing about the trademarking of the name
Robertson in Canada.
Actually Square Drive And Robertson are not the same. The Robertson
drive is tapered slightly toward the point of the bit. The Robertson
holds the screw better. Square drive is not. But like we all know you
can make either work just like the multiple designs of Phillips like screws.

Robert this is why you probably are not getting a good grip on those
bits and screws. If the protrusion on the end of the bit does not fit
the hole in the bottom of the bit the splines are surely not going to
engage properly. I doubt that a normal Torx bit will work any better on
these screws, bur "maybe" they will For your application the head that
Spax uses is probably not going to work well.
And just one more thing, I think. ;~)

That might be the problem. LOL
In another thread, I mentioned that I learned that Mercedes built a

Looks like the Germans are using us to build knock offs. ;~(

Welcome to the dark side! :-)
You're right about their supplied bit. I just keep them around as
spares. Buy some high quality Torx bits and use them. They are much
more forgiving to angled driving.
As I wrote above, get some better bits. ALSO, make sure you have the
proper size. Spax screws use 10, 15, and 20, IIRC. You *can* drive a
20 with a 15 and a 15 with a 10 when you are straight on and don't need
huge torque, but as soon as you angle out a but, they spin. So always
be sure you have the proper size. (You probably did!)
Their interior/exterior ratings are printed on the box. I wish they
were printed larger, but they are there. I believe they also carry a
stainless series, too, for times when you want to be super-safe.

Just a data point concerning SPAX. I used some galvanized SPAX for
various projects a while back including putting together some
scaffolding and attaching a gutter.
Last winter the gutter came down with an ice dam. Looking at it all but
two of the SPAX were broken, not pulled out, and the ones that broke
broke off even with the plastic brackets. Of the two that pulled out,
one of those was also partly broken at the same place as the others.
Also, when taking apart the scaffolding, several of the screws broke at
roughly the same place as the ones holding the gutter.
They were put in and taken out with an 18v deWalt impact driver.
I don't know if this is characteristic of them, or if it was unique to
the batch I have.
I also note that the ones at Home Depot are a bit different from the
ones I have but I haven't compared them side by side to say in what way
I have read all the responses and appreciate the time taken to respond. Th

Going off on a tangent here, but "a bit different at Home
Depot" tends to be a red flag for me. Home Depot is big
enough in volume that they can insist on vendors making a
special, lower cost version just for Home Depot. And it's
a very rare thing for the lower cost version to be of the
same quality as the "standard" version - the vendor has to
make up the cost difference somewhere.
