Threaded Ground Anchor Pack – 2 x 450mm GroundGrabba Pro (Compact Fixtures)

What It’s Best At

This 450mm threaded GroundGrabba is engineered for pull-out resistance—not vertical load-bearing. That means it's ideal when your application needs to resist wind, vibration, lifting, or tipping—but not designed to support the entire weight of a structure.

It’s an ideal solution for:

• Permanent or semi-permanent outdoor signage
• Ground-mounted electrical boxes or switchboards
• Lightweight sculptures and displays
• Steel and timber brackets, base plates, or fencing fixtures
• Grounded rigging systems and tethering points
• Anchor points for test rigs, scientific installations, or shade systems
• Equipment tie-downs in remote or rugged terrain

Built for Professionals Who Need Precision

Whether you're a contractor, engineer, event planner, or technician, this anchor was made with you in mind. It’s perfect for situations where standard GroundGrabba augers with large 40mm flights simply won't fit. Because it relies on threading into the earth after drilling, it delivers more accurate placement and is less invasive to the surrounding area—especially important in heritage or landscaped locations.

Performance You Can Count On

• High-strength GR14 steel – Built with a 15mm shaft and hot-dip galvanised coating for maximum corrosion resistance.
• Threaded design – Grips earth, clay, and compact soil reliably once driven into a pilot hole.
• Easy install – No concrete. No curing. Just drill and drive.
• Low-profile – Leaves a neat threaded shaft above ground for nut tightening.
• Reusable – Designed to be removed and reused again and again on new sites.

Installation Tips

• Use a pilot hole – Always pre-drill with an auger or masonry bit of appropriate depth and width. Anchor will not self-drive.
• Socket tool required – A 24mm deep impact socket is essential for proper torque and depth control.
• Leave thread exposed – Allow 25–30mm of shaft above ground for secure nut fastening. Don’t drive flush.
• Don’t overtighten the top nut – Excessive torque can reduce hold strength by lifting the anchor up out of the ground.

Hook Washer 14—Your Secret Weapon

If your baseplate has a larger clearance hole (e.g. 40–45mm), the hex head of this anchor may slip through. To fix that, we recommend pairing it with our Hook Washer 14. It’s a wide, heavy-duty washer that creates a secure stop point for fastening through larger diameter mounting holes without compromising hold.

• Length: 450mm
