Wood Screws

[check]

That's where I had the most trouble with them in a deck screw version. The heads filled up with junk and got packed in by foot traffic and weather. Nearly impossible to clean out enough to get a driver seated.

I agree that debris is a problem. If I have to remove a bunch of deck boards that have been screwed down with the Robertsons screw I have to first of all get a compressor and blow out each screw head.

In 2004 I built a deck and wanted some easy screws to put in. I was used to #2 Phillips from previous jobs a had a devil of a time putting longer than 1 1/4 ones in anything. I bought 25# of #3 Phillips deck screws and was amazed at how nice they went in.

This year I built another deck and have been looking for #3 Phillip screws but you cannot find them anywhere but I would have loaded up on them. Very, very hesitantly I bought 25# of number 25 Torx head screws and found out they surpassed the #3 Phillips by a lot. I could drive 4" and 5" screws into treated wood like a shot. I am sold on them and now I have a collection of sizes.

Torx are all that's available here, at least for longer ones. Either them or Pozidriv is all I'll get in the 2" and longer department.

Robertson was a Scot that invented the square drive about WW2 era. USA wanted the patent but being a Scot he wanted royalties which were denied and so it almost died then and there.
However the cabinet making folks liked it as it was easy to automate so it has been gaining ever since.

In Canada it is probably 75% of the fastener market and 4 sure the favorite for decking trade.
It adapts very well to hammed driving and one benefit is that it self holds on the end of a driver. Try that with a Phillips.

Then very similar to Phillips is Reed and Prince both which resemble each other but that's where the resemblance stops. The drivers are not exactly the same.

I suspect automation favors the Robertson but beware of cheep offshore production as they do not make the square hole deep enough to make for a good grip.

PS, all my screw stock is Robertson and I stock from 3/4" to 4" in my screw stock.

Yep, sold on the new torx drive screws. Just did a deck using 4" #10's for the joists. Pulled everyone tight, including a few slightly twisted ones. Didn't strip or break a single one. I did another small 6x10 deck for my neighbors shed. Found some 3" Phillips head deck screws at HD, about 1/2 the price of the Torx. Don't know if they were on close out due to the price. They were #10's also, only stripped a couple out, but they were going into knots. I think part of the success driving the screws was using my new (first time ever) impact driver. I think that in itself made a difference with the Phillips screws.

I switched to Robertson years ago, but as SS screws became popular I found them to be soft and easily stripped screw heads in difficult materials. I think that's what most people figured out, since Torx has nearly replaced Robertson style in all quality screws in the box stores. I used all Torx SS screws in a deck last year and it's amazing how much better that style is compared to Phillips or Robertson.
Years ago I would struggle with the old tapered wood screws. They were horrible I thought. Then I found plans to build a maple woodworking bench. The plans called for solid maple with large solid brass wood screws as fasteners. I followed the plans and learned about pre-drilling the proper sized holes for both the threads and the upper shanks, and how that varied by screw size. I also lubed the screws with bees wax. I'm still amazed, thinking back on how I assembled that bench, never messing up a screw head and having every one suck the wood together like I had never seen. I learned a lot and still use those old style wood screws occasionally, now that I know the methods.

Yes, for old slotted wood screws the proper pre drilling is the difference. I still have my dads old carpenter tool boxes and there are a couple different sets of drills that look like a silhouette of various size wood screws for a perfect flush mount pilot hole.

But do I use them? No, right to torx these days! But I appreciate the look you described.

As I remember - back in '82 when I built my decks - Phillips heads were fairly new. I used 3 1/2" Phillips heads and dipped them, by the bunch, in hot bees wax. Insures complete coverage - uses less wax - a whole lot easier that rubbing, one at a time, on a lump of bees wax.

A waxed screw went in so much easier - had to take care not to burry it too deep into the deck board.

I have a set - 4 sizes - of slotted screw drivers. There is an outer tube that will slide down over the head of the slotted screw and hold it in place. I only use slotted brass screws when making antique furniture. Otherwise - just a PITA.

Me too. Robertson is pretty much all I use.

Re Robertson screws; I found that the bit quality makes all the difference, pay a bit more and buy the ones that have the square end press fitted into the shank.
Usually easy to spot as the square insert is generally black.
With a quality bit even a 4" screw can be held without the aid of magnetized bits (but magnet ends are sure my favorite)

Real life story: When hanging my daughter's doors we used quality robertson screws, nice long ones, to assure the hardware would not loosen.
Well she was broken into and the robbers had to seriously kick the door in to access.
Well that steel clad door was seriously bent and the door frame split beyond repair.

Sadly being cottage country these invasions occur all to often with late fall being the usual time frame. Last year 10 homes were hit.

Along with Torex head screws, Simpson ‘Ledger Locks’ beat the heck out of lag bolts and depending on the size are available in torex or hex heads.
I don’t worry so much about the fastener cost it’s the speed, convience,and predictably that counts.
GEK is the brand I like the best for wood and deck screws.
