Specifications
The Daggerz Self-Drilling Metal Screw with Wings is engineered for reliable fastening where wood meets steel. Its unique winged design creates a clearance hole through wood before snapping off at the metal surface, preventing wood splitting and ensuring smooth engagement with steel.
The flat head provides a flush, finished look, while the #3 phillips drive delivers strong engagement for easy driving and reduced cam-out. Finished with Dagger-Guard Coating, this screw offers advanced corrosion protection, making it dependable for both interior and exterior projects.
Key Features:
- Wings: Bore out a clearance hole in wood and break off upon hitting metal for a tight, secure fit.
- Phillips Flat Head: Sits flush with the surface for a clean, professional finish.
- #3 Phillips Drive: Provides strong bit engagement and reduced stripping.
- Self-Drilling Tip: Cuts through steel substrates without pre-drilling.
- Dagger-Guard Coating: Delivers corrosion resistance for long-term durability.
Applications:
- Securing wood sheathing or decking to steel framing
- Attaching subfloors or roof decking over metal joists
- General-purpose wood-to-metal fastening
- Interior and exterior projects where flush fastening is required
Installation Tips:
- Use a #3 phillips bit for best grip and torque transfer
- Let the wings cut fully through the wood before engaging the metal
- Drive straight so wings break cleanly at the steel surface
- Seat the flat head snugly. Do not overtighten to protect the coating and substrate

Self-Drilling Screws with Seemingly Unlimited Options
Our self-drilling screws come in a wide range of options to tackle everything from metal-to-metal and wood-to-metal fastening to interior framing and exterior cladding.

The Right Point for Every Project
Different point types pierce various materials. Standard points handle light- to medium-gauge metal, long points tackle thicker steel, self-piercing points work well in wood or thin metal and winged points clear softer layers before drilling harder substrates, ensuring faster, cleaner and secure installations.
Customer Reviews
Works perfectly as intended! Just some added information the threaded portion is approx. 1 5/8", cutting tip is approx. 3/8", and wood cutting shoulders are approx. 1/8" for a total length of approx. 2 3/8" for the 2 1/2" fasteners. Just putting this out there since the pictures are extremely deceiving. Overall great product for a great price. Will definitely be buying again! Also, customer service was great!
