SELF Drilling Wafer Head Screw #10-16 X 1-1/4" Wood to Metal - Self Tapping TEK Screw T25 Star/TORX Drive (1 Pound - 139 Approx. Screw Count)

These worked phenomenally for attaching plywood to the steel structure of an RV - I'm giving them five stars. Nonetheless, I have one complaint and one area that should be improved. Complaint: On a small number of screws, the epoxy coating is too thick making it difficult or impossible to engage the driver into the head. I'm sure the bit could be hammered in, but I just tossed the few affected fasteners. Improvement: Similar screws from Teks etc. have "wings" to bore through the wood and prevent the threads of the screw from drawing the wood up while the tip drills. If these had that feature, they would be The Best. If you're wondering why I used these screws instead of Teks etc., it's because these have a Torx drive, which is far more reliable and less prone to stripping. For that reason alone I'd buy these again over Teks, but that feature is definitely lacking here.

Haven’t used yet

Used to secure wood top to metal trailer supports. All screws but 5 (no patience) worked as advertised. I would absolutely use these screws again. Glad I wasn't screwed, but my trailer did!!!!! Great product!

Good job on wood

I had bought the treated pine wood for this fence 4 months ago in order to let it dry out. We were in a bit of a drought during that time so the wood was good and dry. I installed the fence and the first time it rained (a little over a week later) the planks of wood started falling off. I had put 6 screws in each plank, 2 on the top, 2 on the middle and 2 on the lower rails. I wrote the seller and they apparently think this is normal. They said the screws weren't defective it's just that the wood swelled when it rained and this is expected. This was normal treated Pine fencing on an aluminum gate, this was the intended purpose of the screws but they failed horribly. The moral of the story is, don't use these screws if it sometimes rains where you live and it doesn't rain at other times, your fencing will fall off and it is apparently expected! Below is the correspondence with the seller. I had written them a 3rd time but they never responded and the 30 days had passed for the return window.From me to seller;I used these to attach 4" wide fence planks to an aluminum frame 2 weeks ago. The wood was treated and sitting in my yard drying out for at least 4 months before attaching to the frame. I live in Texas and we hadn't had rain for nearly 3 months. It rained last week causing the wood to swell, I'm guessing. I walked out after the first rain and 3 of the 25 -30 boards are laying on the ground having snapped all 6 screws in each board. I just walked out there again and I must have 20 or more screws snapped. Was there a defective batch sent out or all of them this bad? My ORDER #From seller to me;Sorry for the issue. When your wood is completely dry from sitting the sun and you reintroduce moisture into the wood there will be swelling causing pressure on the screws. They are not a defective batch of screws. The pressure from the wood expanding is causing the problem. In any application when using dry lumber it is important to accommodate for moisture to be reintroduced and leave gaps in between each plank. Lumber is always going to expand and retract as moisture levels change.

very satisfied with product and in was delivered as advertised which is important for us as we are using the item on a construction project and this allows us to stay on schedule.thanks again !!

Absolutely Top Shelf..Ordering more NOW..Thank you for the quality and fast shipping..

I used these to screw in wooden fence boards to a metal frame. They are perfect. I did need to pre drill the hole to speed the process up. But very impressed with these. So much that I bought more.
