Duplex Multi Use Screw 90mm – 100pk

Powerpac’s Duplex Multi-Use Screw is a reusable, self-tapping formwork fastener built for the demands of concrete construction. With a bright orange hex head that fits straight into any standard 1/4″ impact driver, there’s no need for drill bits, pilot holes, or special tooling Ñ just load and drive.

Each screw is good for 20+ uses, making it a direct replacement for duplex nails and single-use screws in formwork, temporary bracing, and boxing. The Type 17 self-tapping point bites cleanly into timber without splitting, and the dual-head design means fast, clean removal when it’s time to strip. You get cleaner timber, fewer wasted fasteners, and quicker turnaround between pours.

The high-visibility orange head stands out on site Ñ even under concrete splatter Ñ so nothing gets left behind when you’re pulling forms. And unlike nails, the threaded shank grips hard. That means tighter formwork under pressure, fewer blowouts, and less rework.

Whether you’re pouring residential foundations, commercial slabs, or retaining walls, the Duplex Multi-Use Screw is already a go-to for formwork crews and builders across New Zealand. It’s just as useful for site hoarding, temporary fencing, stage builds, and event platforms Ñ anywhere you need to put something up, pull it apart, and do it all again.
