Frequently Asked Questions

The SKU number for this product is SD4CTWW12212. It identifies the Daggerz #12-24 x 2-1/2" Phillips Flat Head Self Drill Screw with Wings supplied in a 1,500-piece carton.

The wings ream a larger hole through wood so the threads do not engage prematurely. When the wings reach steel, they break off and allow the threads to fasten securely into the metal substrate.

These screws are specifically designed for wood-to-steel fastening applications. They are commonly used for attaching plywood, decking, and wood panels to steel framing.

The screw features a #4 self-drilling point for drilling through heavier-gauge steel. This design helps eliminate separate drilling operations and improves installation efficiency.

Each carton contains 1,500 Daggerz SD4CTWW12212 self-drilling screws. The bulk packaging is ideal for contractors, builders, and commercial construction projects.
