Frequently Asked Questions

The SKU number for this product is SD4CTWWST12212. It identifies the Daggerz #12-24 x 2-1/2" Star Flat Head Self Drill Screw with Wings supplied in a 1,500-piece carton.

The wings create a clearance hole through wood before reaching the steel substrate. Once the screw contacts steel, the wings break away, allowing the threads to engage properly.

The T-27 star drive provides better bit engagement and reduces cam-out during installation. This helps improve productivity and minimizes driver wear.

These screws are ideal for fastening wood components to steel framing, metal structures, and decking systems. They are commonly used in commercial, industrial, and residential construction projects.

Each carton contains 1,500 Daggerz SD4CTWWST12212 self-drilling screws. The bulk packaging is suitable for contractors, fabricators, and high-volume construction applications.
