Review on U-Turn - 10-16 X 1-5/8 Flat Head Phillips Wood To Metal Self Drilling Screw Tek 3 With Wings Zinc Plated (50 Pack) by Chris Cruz

Do not buy these screws. Please listen to me. I use a lot of self tapping screws. I bought them for a trailer. NOT screwed into 1/8" steel with no pilot hole. I had to buy real trailer deck bolts. Failure rate 50%. I'll give you the 75 I have left. Torx t30 nuts. I didn't read the fine print on them and they came with Phillips -Heads, which isn't good. The company hides that these aren't torx sockets. That's why they don't show the head picture. Buy torx pan head trailer bolts.
