Simpson Strong-Tie #12 x 2-1/2″ Self-Drilling Screw with Wings, Flat Head – 410 Stainless Steel, Qty. 1,000

When you need to fasten wood, plywood or fiber-cement board directly to steel framing without pre-drilling, this Simpson Strong-Tie F12C250FDM Self-Drilling Flat Head Screw With Wings delivers the performance you expect.
