Water penetration around screw holes is a common source of roof leaks. The integrated EPDM washer on each screw forms a tight seal that blocks water from seeping through. EPDM rubber is highly resistant to UV rays, ozone, moisture, and temperature fluctuations, providing reliable protection in any climate. Screws are constantly exposed to moisture, rain, and environmental pollutants, which can cause rust over time.

We understand that successful fastening isn’t just about making two pieces hold together—it’s about joint integrity over time, environmental exposure, ease of installation and cost‑effective results. Blind rivets are increasingly in demand because they address access‑limited joints: you only need one‑side access, no backside tooling or nuts, and you get consistent setting with speed.
