Heavy Duty Screw-In Parasol Umbrella Base Stand & Ground Anchor Spike

Heavy-duty screw-in ground anchor for parasol, umbrella and flagpole bases, designed to give a solid, upright fixing point in lawn or border soil without digging a hole, mixing concrete, or waiting for anything to cure. The anchor is ready to take a pole as soon as it is driven home, making it a practical alternative to a traditional buried base for anyone who wants a genuinely stable footing without the groundwork.

The defining feature is the helical screw thread running along the lower 310mm (12.2in) of the spike: turning the anchor draws it steadily down into the ground rather than requiring it to be hammered or pushed in, and as it turns, the thread compacts the soil around itself, forming a firm grip that resists both pull-out and sideways movement once the anchor is fully driven in. The tube itself is manufactured from 1.8mm (0.07in) S235 structural steel and hot-dip galvanised to BS EN ISO 1461, giving the anchor the corrosion resistance needed to stay buried in damp soil through UK seasons without rusting through.

At the top, the socket has a 68mm (2.68in) outer diameter and a 64.4mm (2.54in) bore, and comes complete with six reduction inserts – 60mm, 55mm, 50mm, 42mm, 36mm and 26mm (2.36in, 2.17in, 1.97in, 1.65in, 1.42in and 1.02in) – so the same anchor grips round poles anywhere from 26mm up to 64.4mm (1.02-2.54in) in diameter, covering everything from a slim washing line pole to a substantial parasol post. An M8 bolt, included with the anchor, threads into the socket wall to lock the pole securely in place once it is fitted, so there is no reliance on friction alone to keep the pole upright.

Key Features

• Helical screw-in ground thread (310mm/12.2in) drives the anchor into lawn or border soil without digging or concrete
• Hot-dip galvanised to BS EN ISO 1461 for long-term corrosion resistance in damp soil
• 1.8mm (0.07in) S235 structural steel tube for a rigid, durable anchor body
• Socket accepts poles from 26mm up to 64.4mm (1.02-2.54in) diameter via six reduction inserts (60mm, 55mm, 50mm, 42mm, 36mm, 26mm)
• M8 locking bolt included, threading through the socket wall to secure the pole in place
• 550mm (21.65in) overall length gives a deep, stable anchor point below ground
• Compact 2.14kg (4.7lb) weight: a substantial, robust anchor

Specification

Typical Applications

• Parasol and umbrella bases – anchors a garden parasol or umbrella pole firmly into a lawn or border, holding it upright against sideways movement without a heavy weighted base cluttering the patio
• Flagpoles – gives a flagpole a solid, level footing set directly into the ground rather than propped in a freestanding stand
• Rotary washing line poles – secures a rotary drier post so it stays upright and doesn't work loose or lean over time as the line is loaded and turned
• Bird feeder and bird table posts – holds feeding posts steady in a border or lawn, resisting the knocks and gusts that can topple a loosely set post
• Garden thermometers and ornament poles – gives smaller decorative and instrument poles a fixed, upright footing that won't tilt over the growing season
• Other free-standing round poles – any round pole or post between 26-64.4mm (1.02-2.54in) in diameter that needs a firm, level footing in lawn or border soil, thanks to the six-insert reduction system covering that whole range

Installation Guidance

Position the anchor point-down on the spot where the parasol, flagpole or post is to stand, and turn it steadily into the ground, checking with a spirit level periodically so the socket stays upright as it goes down. In most garden soil the helical screw thread will draw the anchor in on its own, without any need for a pilot hole; in hard, stony or heavily compacted ground, starting with a small pilot hole makes turning easier and helps keep the anchor running straight. Once the anchor is driven down to the depth you want, select whichever of the six reduction inserts matches your pole's diameter and fit it into the socket, drop the pole in, and tighten the included M8 bolt through the socket wall to lock it firmly in place.
