The Bolt Down Post Shoe Quick Fit HDG is a straightforward solution for setting fence posts without digging or concreting them into the ground. The shoe fixes directly to an existing concrete pad, slab, or timber base using bolts through the base plate, then the post drops into the collar and is secured in place. The result is a solid, permanent fence post base that holds firm once installed properly.
Hot dip galvanising gives this shoe the corrosion resistance needed for permanent outdoor use. The HDG coating is applied by immersing the steel in molten zinc, which bonds to the surface and protects it from rust far more effectively than a painted or electroplated finish. For fence installations that are meant to last, that matters.
The quick fit design speeds things up on site. There is no need to mix concrete around every post or wait for it to cure before moving on. You bolt the shoe down, drop the post in, and fix it through the pre-drilled holes in the collar. If a post ever needs replacing down the line, the shoe stays in place and the new post simply slots back in. That is a genuine convenience that you only really appreciate the first time you have to swap out a rotten post.
Where Bolt Down Post Shoe Applications Make Sense
This type of fence post base is well suited to situations where digging is not practical or desirable. Installations on concrete yards, paved areas, driveways, timber decking, and hard standings are all typical uses. It is also the right approach where ground conditions make post driving or in-ground concreting difficult, such as shallow soil over hardcore or areas with underground services close to the surface.
The two available sizes cover the most common timber fence post dimensions. The 75mm shoe suits standard 75x75mm posts used in most domestic and light commercial fencing. The 100mm shoe handles 100x100mm posts, which are commonly used for heavier panel fencing, agricultural gates, and perimeter fencing where a stronger post section is specified.
Sizing and Installation Notes
Always check the post section size against the collar dimensions before ordering. The post should fit snugly into the collar with no significant play. A sloppy fit will compromise the rigidity of the installation. When bolting the base plate down, use appropriately sized masonry anchors or coach screws for the substrate, and make sure the shoe is positioned accurately before drilling, because adjusting bolt positions after the fact is more work than it sounds.
For exposed locations or coastal areas, the hot dip galvanised finish on this fence post base is the appropriate choice. A standard zinc-plated or self-colour fitting would not hold up to the same level of weathering over time. The HDG shoe is intended to outlast the timber it holds.
Pro Tip: When fixing to a concrete base, use M10 or M12 chemical anchors rather than mechanical expansion anchors if the concrete is thinner than 100mm, as expansion anchors can cause the slab to crack under the shear loads a fence post transmits in wind.
The Bolt Down Post Shoe Quick Fit HDG is used wherever a fence post needs to be secured to a hard surface rather than driven or concreted into the ground. Typical applications include garden fencing on concrete bases, perimeter fencing on paved commercial yards, decking edge posts fixed to timber joists, driveway entrance posts, and gate posts set onto existing concrete plinths. It is also used in agricultural settings where posts need to be positioned over compacted hardcore or concrete standings.

Not suitable for: Not suitable for use in soft or uncompacted ground where a base plate cannot be firmly anchored. Not designed for round section posts.
Fix the base plate to the substrate first, using appropriate fixings for the surface, whether masonry anchors into concrete or coach screws into timber. Use a level to confirm the shoe is sitting true before the fixings are fully tightened. Once the plate is secure, drop the timber post into the collar and check for plumb in both directions.
With the post plumb, fix it through the pre-drilled holes in the collar using the appropriate bolts or screws. Where multiple posts are being installed in a line, set all the shoes first and check alignment before fixing any posts. This saves adjustment work later and keeps the fence line straight.
Mark the post positions accurately on the substrate before drilling

Fix the post through the collar's pre-drilled holes
Check alignment with adjacent posts before moving on to the next fixing
What size bolt down post shoe do I need for a standard fence post?
Most domestic fence panels use 75x75mm posts, so the 75mm shoe is the right choice for those. If you are using heavier 100x100mm posts, for example on agricultural fencing or gates, go for the 100mm size. Measure the post section before ordering rather than guessing.
Can the bolt down shoe be used on timber decking as well as concrete?
Yes. The base plate can be fixed to a timber substrate using coach screws, making it suitable for securing posts on decking frames and timber platforms as well as concrete bases. Make sure the timber is sound and of sufficient thickness to hold the fixings properly.
Is the hot dip galvanised finish suitable for long-term outdoor use?
Hot dip galvanising provides significantly better corrosion resistance than electroplated or painted finishes. It is suitable for permanent exterior installation in most UK conditions. For coastal or very exposed locations it will perform well, though like any galvanised steel product it should be inspected periodically for any signs of coating damage.
The Bolt Down Post Shoe Quick Fit HDG is manufactured from mild steel and finished with a hot dip galvanised coating, which bonds a layer of zinc to the steel surface for long-term corrosion resistance. The base plate is pre-drilled to accept standard masonry anchors or coach screws. The collar section is sized to accept 75mm or 100mm square timber posts depending on the variant selected, with pre-drilled holes for post fixing bolts or screws.
