Ground Screw Fastshifter Trident Drive S 68×350 M16x120 HDG

The Ground Screw Fastshifter Trident Drive S 68×350 M16x120 HDG is a Fastshifter Trident Drive ground screw — a compact, hot-dip galvanised screw foundation with a three-blade drive geometry that pulls itself into the ground quickly and holds firmly in soft and loose soils.

The shaft measures 68 × 350 mm and it is topped with an M16 × 120 mm threaded stud, so posts, brackets, base plates and levelling nuts bolt straight on.

Key features

• Trident Drive blade geometry — draws itself in and grips well in soft, sandy and made-up ground.
• M16 × 120 mm threaded head — direct bolted connection with height adjustment via nuts.
• Hot-dip galvanised — full corrosion protection for permanent outdoor installation.
• Short shaft, hand-installable — no machine needed for most garden work.
• No concrete — install and build in the same visit, in any season.
• Removable and reusable — unwind and re-drive if the layout changes.

Where it is used

• Lamp posts, bollard lighting and signage.
• Fence posts, gates, screens and trellis.
• Light garden structures — arbours, benches, planters, bin stores.
• Playground equipment and small timber frames.
• Temporary structures that need to be dismantled cleanly.

Drive the screw with a turning bar until the threaded head sits at the required height, check for plumb, then bolt the post or bracket in place and level with the nuts.
