Small Parts 1024KWTF Steel Self-Drilling Screw, Zinc Plated Finish, Wafer Head, Star Drive, #3 Drill Point, #10-16 Thread Size, 1-1/2" Length (Pack of 50)

Worked perfect on a boat floor rebuild. Was the perfect size, finish.

Worked fine after I predrilled oversize holes in the plywood deck. No breakage. Did have one (out of 21) that did not self tap. I used another screw to drill and tap the hole and replaced it with the dull screw. The waffer head and torx drive were what I wanted for this project.

I used these on 14 gauge steel tube and about every third one of these had the tip break off, making it useless. I'm not a big metal guy, so maybe this is normal? When they worked, they worked really well! And if it weren't for the star drive, I probably would have thrown the whole bag in the trash! If you don't use a lot of self-tappers, or you need them for a lighter gauge sheet metal, these are fine, just buy more than you need!

Great Product! Fast Shipping! Recommend Seller!

not the best self drilling screws i’ve had, very difficult to get started even with a impact drill

I use these to hold down the plywood decking on my trailer. I like them because they go And nice and smooth so the head doesn’t stick up

Wanted to use to secure a plywood deck to the frame of my 4'x8' utility trailer. Very disappointed. First, need to use a small T20 rather than a more standard T25, Second, even with a pilot hole drilled, the screw heads keep stripping or snapping off. May be ok for a lighter duty sheet metal job, but NOT for securing to steel tube/angle/etc.

When you need a self-tapping screw with a large head on it this is the way to go these work great would buy again

No issues yet will advise if there is any problem with these fasteners. Glad the required size was available.

I would not buy these again, they broke off when drilling , had to pre drill the hole so I could finish the job Poor quality

Used to mount foam insulation in enclosed trailer screwed in with ease

Look good, decent bit into the metal. I found only 1 out of 3 would self drill, the others would round their point. Small pilot hole first is suggested

Besoin d une drill pour percer avant car la tête perceuse ne perce pas, après ça fait quand même la job !
