Got these. #12x1.25". Overpaid for sure but I detest Home Depot and Lowes these days. It's like no one works the floor and the people that do know almost nothing. This was easier than looking through and isle of screws in boxes or bags.
#12 x 1-1/4" (1/4" to 3" Available) Hex Washer Head Self Drilling Screws, Self Tapping Sheet Metal Tek Screws, 410 Stainless Steel, 50 PCS
