Powerful Anchoring Where Standard Anchors Can’t Go
Need a deep-set anchor but your project’s mounting holes won’t fit a flighted GroundGrabba? The 600mm Threaded GroundGrabba was made for exactly that. Purpose-built to solve the common problem of small-hole compatibility, this threaded anchor delivers professional-grade hold in locations where hex-head or flighted options won’t work.
Designed for Narrow Access and Tough Terrain
This anchor is ideal for fixing through steel base plates, timber templates, brackets, and gear that has pre-drilled holes as small as 15–25mm. With no flights and a clean threaded shaft, it fits through compact openings where standard GroundGrabba Pro or Pro I anchors simply can’t pass.
The 600mm threaded model provides longer penetration and greater stability than our 450mm version, making it ideal for anchoring taller or heavier structures in harder ground—especially where depth matters.
Fast, Clean Installation
To deploy this anchor:
- Position your item or structure exactly where it needs to sit.
- Drill a pilot hole through your gear’s mounting hole and into the ground using a masonry bit suited to the soil type.
- Remove the item, then insert the 600mm anchor and drive it in using a 24mm deep impact socket (not supplied).
- Leave enough thread above ground to allow for a nut and washer to fasten your item securely.
Important: Do not overtighten the top nut. Excess torque may pull the anchor upward and reduce holding strength.
What Makes This Anchor Different?
- Threaded Design – No flights means it fits where standard GroundGrabbas can’t
- Longer Length – 600mm shaft provides added bite for heavier loads or taller items
- Premium Steel – Manufactured from toughened steel and finished for durability in outdoor conditions
- Removable & Reusable – Ideal for temporary installs, event setups, and field testing rigs
- Fast No-Mess Setup – No concrete, no digging, no drying time
Perfect for Engineers, Installers & Field Techs
This model is especially useful for engineers, contractors, and installers who regularly need to mount gear or structures using existing holes or templates. It provides fast, secure fixing without modifying equipment or cutting oversized holes for standard anchors.
Ideal Applications
- Art installations and public sculptures
- Modular signage and light structures
- Weather stations and scientific test rigs
- Solar inverters and micro-pole systems
- Audio-visual towers or cable trays
- Temporary fencing, stanchions, and utility enclosures
Tooling & Compatibility
- Socket size: 24mm (deep socket required)
- Mounting hole compatibility: ~15–25mm internal diameter
- Fasteners: Secure with appropriate nut and washer (not included)
If your project requires a 450mm option instead, check out the 450mm GroundGrabba Threaded Anchor. For extra bite and larger installs, consider stepping up to our 900mm version.
Why Threaded GroundGrabbas?
Threaded GroundGrabba anchors were developed for projects where our traditional hex head and wide 40mm flights are simply too large to pass through narrow openings. These anchors retain the same high-strength steel and installation simplicity of the GR14 ecosystem, but are streamlined for specialist applications.
They are not a ‘lesser’ option—just a different tool for a different job. And like all GroundGrabba anchors, they’re backed by our lifetime replacement warranty.
Installation Tips from the Field
"We use the 600mm threaded anchors to secure high-end equipment enclosures where pre-drilled holes leave no wiggle room. They save us so much time—no modifying gear, no dodgy retrofits." — Nathan B., AV Integrator
