Review on 🔩 SML C1 500: High-Quality Coarse Washer Head 1 Inch - 500 Pack by Michael Radhakrishnan

I bought these to connect 1/2 inch plywood to a pocket hole and they came with it. The box is strong enough to hold together for a while so I don't have to toss screw scraps in a coffee can. The screws themselves will work as intended when installed in a properly drilled blind hole. QC on them is quite high; I have used thousands of 1-1/4 and most of this box and have not come across one that was improperly formed or broken off at the head.
