Fence post support buying guide
Updated: October 2026
You are standing in the garden with a tape measure and a leaning panel. This fence post support buying guide is the decision before any brand: repair stake, bolt-down shoe, drive-in socket or elevated base, then the real size of the timber and the finish the ground will tolerate. Peter F. used the twelve amazon.co.uk listings in the [post support comparison](/hub/fencing-and-wire/post-support) on 19 October 2026. We did not load-test them. A qualifying purchase can earn a commission at no extra cost to you.

Which support matches the job
A drive-in repair stake screws to timber that is still sound and is driven in soil beside the old concrete. East Coast Fencing’s limit is blunt: if the post is soft, the stake has nothing to bite. A drive-in socket belongs in firm, stone-free soil. DIY Doctor lists sockets of 50, 75 and 100 mm, at 600 and 750 mm. A short spike under a tall closeboard run is the mismatch they tell you to avoid.
A bolt-down shoe needs a patio, path or shed base thick enough for anchors. An elevated base holds the end grain off a wet surface when a frame already restrains the post. Bendrey Bros say that family is not a free-standing fence post. Soft timber more than a short way above the ground means a new post. The method argument is fence post spike vs bolt down.
Measure the post, then the shoe
Nominal names are a poor substitute for a tape. Romford Fencing describes a nominal 4x4 as typically about 100 x 100 mm. Measure both faces. A post sold as 4x4 can arrive nearer 95 mm, and a loose shoe will not tighten because the title said 4x4.
The Xingwenhao bracket is the best value listing and the one that prints a range: 38 x 38 mm, 50 x 50 mm, 50 x 101 mm and 101 x 101 mm. The Vigtayue shoe claims a true 4 x 4 inch post. Reviews both confirm a fit around 95 x 95 mm and report a shoe that was too big. The VEVOR title is 2 x 2 inches, about 50 mm, not a 100 mm fence post. Several repair stakes print no section at all.
Galvanised, plated or powder-coated
Galvanised on an amazon.co.uk title is the seller’s word until a standard is named. Hot-dip to EN ISO 1461 is what Simpson states on its PPA elevated base, a documented connector and not one of these twelve ASINs. Do not copy Simpson’s load figures onto an unrated screw jack. The Domax foot says hot-dip galvanised, 4 mm steel, made in Poland. Reviews still describe rough welds and poor-looking zinc. The screw-jack listings say galvanised or electroplated and do not cite EN ISO 1461. Powder coat, the black finish on several stakes and on the Vigtayue 4x4 shoe, is a different coating.
Fixings fail in the reviews even when the steel looks plausible. Xingwenhao’s supplied screws are reported stripped. The Vigtayue shoe’s self-tappers are reported to rust quickly. Budget your own exterior screws and, on masonry, anchors sized for the slab.
What the prices in this set buy
The captured amazon.co.uk prices are this set only, not a national survey. Entry is about £8 to £13: Domax at about £7.97, Xingwenhao at about £10.99, and the AOOTE 2-pack at about £12.74. Mid is about £18 to £24, including AHAQU and FWEEK at about £23.99. The upper end is about £29 to £34, with Anmas Power at about £29.99 and VEVOR at about £33.90. Bendrey Bros list a Simpson PPA100 at about £32.62 including VAT, outside this comparison.
In England, GPDO 2015 Class A puts a fence over 1 metre next to a highway used by vehicles, or over 2 metres elsewhere, outside permitted development. Changing a post is not a free pass to raise the panels. Posts in the ground should be Use Class 4 timber.
Common questions
Do I need a repair stake, a shoe or an elevated base?
You need a repair stake when sound timber is leaning in soil and old concrete blocks a new hole. You need a shoe when the post bolts to a slab or a deck that can hold anchors. You need an elevated base when a frame already holds the post and you want the end grain off the wet surface. A gate, a tall exposed run, or soft timber means a new post.
Is a 4x4 shoe actually 100 mm?
In UK trade descriptions a nominal 4x4 is often about 100 x 100 mm, and it can be nearer 95 mm. The Vigtayue shoe claims a true 4 x 4 inch rather than 3.5 x 3.5 inches, and reviews both confirm a 95 x 95 mm fit and report a shoe that was too big. Measure the post. Order the shoe that matches the tape, not the name on the timber receipt.
Will a 2 x 2 inch anchor fit my fence post?
It fits timber of about 50 mm, which is what a 2 inch size means on a UK bracket page. A typical garden fence post nearer 100 mm will not enter that cup. The VEVOR title in this set is 2 x 2 inches. Packing the gap with offcuts is a review workaround, not a specified fixing.
Does galvanised mean hot-dip?
Only when the listing says hot-dip, and only to EN ISO 1461 when that standard is named. Domax says hot-dip. The screw jacks say galvanised or electroplated and do not cite the standard. Powder coat is a different finish. Bring exterior screws anyway, because supplied screws are a repeated complaint.
Can I use an elevated jack as a fence post?
Use it under a post that a pergola, a trellis or a similar frame already holds. Bendrey Bros exclude free-standing fence posts from this family of elevated bases. A 100 mm to 150 mm screw jack does not become a fence post because the star rating is high. The AHAQU base is the top pick for that light restrained job, not for a panel that stands on one foot in the wind.
