Customer Questions & Answers

will they work for attaching 2"x4" treated fence framing to 16 gauge steel terminal post?

Asked by: Rick
That is 1/16" and I would guess that is on the thin side of this screws limits. These screws are used a lot for attaching wood flooring to trailer frames. Trailer frames are angle iron and roughly 1/8" to 1/4" thick metal. That gives the screw enough metal to cut a good thread channel. I would be afraid that over time with wind and stress the screws would pull out of 1/16" metal. I would drill all the way thru the post and use 1/4" stainless or galvanized carriage bolts with nuts washers and split lock washers or locknuts . Maybe use fender washers on the wood side.

can i use to screw a metal piece on top of wood?

the wood im using cannot be moved and i cannot get under it to drill so can i use these and go through the metal first? if not what can i use to go through metal first?
Asked by: sierra7
Use a wood screw or lag bolt and just drill a hole in the metal a slightly larger diameter than the shaft of the screw / lag bolt. You should also pre-drill the wood with a smaller hole than the screws shaft. The drill bit should be just smaller than the shaft of the screw minus the screws threads. If the screws are small then you can skip pre-drilling the wood.

Can I use it to attach wood to wood?

The product says it is used for attaching wood to metal and I find no other item in Homedepot that specifically says wood-to-wood attachment. I wondering if I can use it to attach wood to wood.
Asked by: DSKim
You could but it would not be efficient use of this screw. These screws are hardened steel for cutting threads in metal. You need to use wood screws. Use deck screws if its outside so they don't rust.

Would these be good for aluminum window installation?

We're installing 45"W x 70"H aluminum windows to a 1960s house. Would these screws be good and not corrode in the aluminum window. They will be screwed to the wood frame directly

#12 2-3/4 in. Phillips Flat-Head Self-Drilling Screws (40-Pack) is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Great for applying deck to utility trailer Used these to secure a fresh new Pressure Treated SYP deck to my 18' trailer. I had to apply a lot of force to get them to penetrate the steel framing, but they pulled the deck down nice and tight to the frame.

Rated 5 out of 5 by from Well worth the money! Great for redecking utility trailers. I just wish I would've known about this product before I spent $20 on stainless steel sheet metal screws & waisted about a 1/2 hour trying to drill one pilot hole! I was able to screw all 26 screws without drilling pilot holes and with my cordless drill.

Rated 5 out of 5 by from The only way to attach fence rails to square steel posts Like others have said, you have to push a bit to get them to drill into the metal, but they cinch down tight. I was replacing 2x4 treated rails and fastening them to square steel posts set in the ground. It was tough going until a brother-in-law suggested I might want to invest in an impact driver. Much easier due to the impact hammering action of the driver. Still have to push some. Noticed that on the wetter pieces of the treated 2x4's, it was almost like the wet wood chips were keeping the drill point of the screws from biting into the steel unless considerably more force was applied. Solved that by having a second cordless drill handy to quickly drill a pilot hole. Having the pilot hole also makes guiding the self-tapping screws easier.

Rated 5 out of 5 by from Great screws Love these screws. Used them many times on different projects and will use them again and again. Got to put some weight behind them to get them to bite through so be prepared for a workout.
