Hi, could someone recommend a good power screwdriver.
I will be using it mostly to build temporary walls
that will be tore down after the project. I would
like to reuse the lumber. I have many drills, my
problem is I buy the screws and the bit to and they
slip off or as soon as the screw meets any resistance
the bit strips the screw. I would like to buy a good
screw driver or a special chuck for my multitude of
corded variable speed drills. I have a Home Depot
close by. Any recommendations?
This is Turtle.
There is 3 types of phillips screw driver heads and you have to get the # 1 , # 2 ,
or the # 3 to fit the size of the slot of the
head of the screws that your using. If you have the right screw head to fit the slot
of the screw head. it will not slip.

It sounds like bits and screws dont match Square drive might be better
for you. A screwgun wont help if you have variable speed on your drills
, go slower. and get good bits , alot are crap or predrill.
Thanks for all the sugestions guys, tomorow morning I
will pass an Ace Hardware and I will stop in and see if
they have some "Robertson Screw Square-drive screws".
Also if I remember correctly the lumber yard sells screws, I will check
there also. Thanks again, I will check back and let everyone know how I made

Yes, I've bought them at Home Depot. They're often sold for securing
deck boards to joists. The ones I've bought have a light tan colored
anti-rust coating on them. (Though I don't know how well that'd work
with the currently produced pressure treated lumber. I hear that nothing
less than stainless hardware will hold up "forever" with that stuff.)
Th "Robertson" square drive screw IIRC has a square recess in the head.
The "Phillips Square Drive" combines that square recess with cross slots
similar to those on a regular Phillips head screw. Robertson screws have
been used for years in furniture manufacturing and are beginning to
penetrate other markets. McFeely's has a good selection of them:

It's Robertson. I get my Robertson square drive screws from
McFeely's. I think there's a web site, so try googling.
They really do work. I'm not the strongest person in the world, but I
can drive square drive screws a lot easier than slots.

First, are you pressing hard enough?
You have to press hard enough that the bit does not become
forced out by the torque being converted into a push back along
the line of the bit.
You should start out pressing lightly, and as the screw goes in
press harder and harder.
Try hard to keep the bit in line with the screw.
A dab of grease makes the screw go in easier, and reduces the need
to push so hard.
The bit should be able to hold onto the screw if you put it on when
You should also have the drill set to a moderate speed.
A torque limit is often handy, but you can usually make do with a speed
limiter, and progressive trigger.
Driving the screws in at full speed and expecting the screw/bit to
be able to bring the inertia of the drill running at a high speed to
a rest in a fraction of a turn just asks for the bit to slip, or
break the screwhead.
Assuming that you are not using Philips screws and drivers and they are
matched for size and you are keeping the drill aligned and reasonable
pressure and not meeting excessive resistance, then I suggest square drive
screws. They are sold just for that use. They are made by a number of
manufacturers. Make sure you are using the right size driver for the
screws. They cause much less problems and are easier to use.
If the screws are very hard to turn, you may need to pre-drill pilot
If you already have a variable speed drill, that will do as well as a
power screwdriver. A common problem people have is using a bit that
doesn't fit the screw head, not using enough pressure, and not keeping
the bit centered and aligned with the screw. The best device I have
seen to help with this is a magnetic bit holder that also has a tube
that can be slid forward to cover the screw. I know Stanley makes them;
I'm sure others do too. With the tube slid forward, the screw is held
in alignment; as you drive the screw, the tube slides up until it
uncovers the head of the screw just as you sink it. If you can find one
of those, do a couple of practice screws so you know just how much
pressure is needed. This will work for your application, as you aren't
doing fine carpentry; were you making furniture, a problem would be that
the tube can mar the wood as it is pushed up.
SPAMBLOCK NOTICE! To reply to me, delete the h from apkh.net, if it is
Forget Home Despot, they sell cheap stuff. I've used their screws in the
past but won't any more. Get good screw from someplace like
www.mcfeelys.com Buy square drive screws and buy a couple of the bits and
you will be in business. Or get Spax brand from www.leevalley.com
Square drive (Robertson style) tend not to cam out when you reach the end
and need more torque. I just put together a chaise lounge using about 160
screw up to 2 1/2" long and had no problems, no pre-drilling. I did drill a
recess as I was covering the screw heads with plugs, but no pilot holes.

If you prefer a corded drill get one with variable 0-600rpm speed. Anything
faster will make controlling the operation totally miserable.
Milwaukee and DeWalt 18V cordless drills (on low speed) work well with
Robertson square drive screws, which are getting more common every day.
Check out the Senco screw driving systems now available. Details on their
website. Might be something there you would prefer, and available through
Amazon or even your local lumber yard (my preference). HTH
