Agrifirst Self-Drilling Screws are precision-engineered fasteners for greenhouse construction. The integrated drill-point tip cuts through GI steel tubing without needing pilot holes — dramatically speeding up greenhouse assembly while creating cleaner, more precise joints than manually drilled holes.
Key Features
- Self-Drilling Tip — Drills and fastens in one step — no pre-drilling required
- Corrosion Resistant — Zinc-plated or stainless steel options for greenhouse longevity
- High Pull-Out Strength — Thread design ensures firm grip in GI steel
- Hex Head — Easy driving with standard socket or drill attachment
- EPDM Washer — Optional rubber washer for watertight joints
