Jake Sales #14x3-1/4 Reamer Tek Torx/Star Head Self-Drilling Wood to Metal Screws - for Flatbeds, Trailers or Fastening Wood to Steel - T-30 Torx Screw Head (5 POUNDS - 150 Approx. Screw Count)

Bought these to attach 2x6 pressure treated lumber to a steel frame on an ATV bridge over a small stream. They worked perfectly for that application. I drilled a pilot hole through the 2x6's, then used these self-drilling screw to attach the lumber to the metal frame. The steel frame was about 1/8" thick. The screws drilled through in about 15 seconds each, using a variable speed 3/8" corded electric drill and torx/star driver. Worked quickly, and perfectly. Excellent product.

Got these for replacing some rotted floorboards in a horse trailer. Worked perfectly going through 2x8 into 1/4in aluminum angle. Use impact driver and be ready to stop once the threads bite into the metal

Easy to break off. Used on a trailer deck, boards warped a little and broke several.

Bought these screws to replace the floor in my gooseneck trailer and ended up ordering 340 of them. Had to drill about 75% of the holes because the screw would not drill into the angle iron. As far as the screw itself, good screw and none broke, and none of them stripped the head out. I’ve had self tapping screws before that drilled better than any drill bit. I have a handful left over, I’m going to sharpen them up and try them, they look and feel dull.

We had three Sunbrealla-covered awnings that rotted away and the replacement cost is now exorbitant, to say the least. Now we are left with three awning pipe frames and what to do about it, the dear wife came up with replacing the fabric with 1"x2" wood slats and the picture shows the beautiful and durable result.Used 312 of these very high-quality, self-drilling screws at an acceptable price. Each slat required 4 screws which we predrilled both the wood slat and the pipe with a 3/32" drill bit. We decided to pre-drill for each screw because going into a rounded pipe would not be possible. The wood now penetrated and served as a guide to the screw tip going into the pipe, which might otherwise slip around. Worked out beautifully but had to set the drill chuck cam out at (stop drilling) number 12, otherwise the screw would go in too far into the wood. Highly suggest you practice a dozen times or so to get used to this type of screwing or you may get bad results here and there in your project.Have a bunch of screws left over but the price for them was very good anyway.

I've been using these screws to attach framing and OSB to the steel in the shop.Definitely the best value for this quality of screw.Zero issues and the self tapping works well.I recommend you buy from Jake Sales. I'll be back for more

Great idea , but these bolts will NOT drill into steel. You will have to drill a Pilot Hole, before installing.

They sell quality products. Not junk. Someone took the time to put these packages together. Very happy.

Purchased them to deck over my equipment hauler, I recommend pre drilling the holes first, excellent product, definitely buy again

I fastened the new deck planks on my 16 foot trailer. These screws work very well for that as they are self threading. The only thing that I found is that there are some variations in steel strength and so some holes had to be pre drilled.

pour avoir essayé une multitude de marque / modèle de vis auto-perceuse / auto-taraudeuse, celles-ci sont un niveau TRÈS supérieur... je les utilise pour visser du contreplaqué 1.5"( 2 X 3/4") à des montants d'acier de 1/8" d'épaisseur, la mèche perce l'acier sans problème, les filets tirent vraiment très fort, au point de traverser le contre-plaqué sans problèmes ... ceux qui ont des problèmes avec ces vis font quelque chose de pas correct ou n'ont pas les bons outils ... Plus chères, mais .... wow !

Self tapping screws work alright, they don't do 1/4 inch steel with one screw, they go dull before penetration. 1/8 inch is fine, 3/16 is max

Hard to find a proper tek screw for wood to metalThis was perfect for my needsSecuring deck board onto on ground pool frame as a top copingPricey but worked greatYou will need to buy a good bit
