EPDM washer ST 3.5 hex flange head self drilling roofing screws
Unlike self-tapping screws, self-drilling screws need no pilot hole to cut and fasten; they can drill, tap, and fasten in one go, which saves you the extra step of drilling, then fastening. These screws can fasten metal to metal, wood to metal, and work well with light, low-density materials.
