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
Asked by: Bobbi
Use sheet metal screws.

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 1 out of 5 by from Not good for light gauge metal These screws are not good to use with light gauge metal stud framing.

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.

Cross members were 1/8" angle which should be well within the capabilities listed on the package. First screw torqued into two pieces when it started penetrating the angle. Next four screws rounded out and would not drill through the angle at all. Went back to the old method of drilling pilot holes first and everything went OK from that point. Disappointed in the performance of these on what should have been an easy job.

Worked perfectly and easily. I admit I was skeptical about how they would work, but they did so well I was done attaching the 8 pieces down in less than a half hour. Recommend highly for this application.

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.
