The HDG flush fit bolt down shoe is one of those fittings that quietly earns its keep on just about every fencing job. Instead of digging holes, mixing concrete, and waiting around for a base to cure before you can even think about putting a post up, you bolt the shoe to an existing concrete surface and drop the post straight in. Job done, fence goes up same day. Available in 75mm and 100mm sizes to suit standard timber fence posts.
Hot-dip galvanising means the coating gets into every recess and corner of the fitting, not just the flat faces. That matters outdoors where moisture gets everywhere it shouldn’t. These shoes are built to sit on concrete drives, patio slabs, wall tops, and hard standings without corroding away quietly behind a fence panel. The flush fit design keeps the base plate tight to the surface, which stops water pooling under the shoe and gives a cleaner finish than some of the older-style raised designs.
Where the HDG Flush Fit Bolt Down Shoe Gets Used
Garden fencing is the obvious application, but these shoes work equally well fixing posts for trellis, pergolas, carports, and boundary panels onto existing concrete or block paving. If you’re working on a job where the ground is already hard-landscaped and your customer definitely doesn’t want it dug up, this is the product you reach for. Landscapers and fencing contractors use them regularly for exactly that reason.
The flush fit bolt down shoe is also useful where traditional post installation simply isn’t practical, such as on flat roofs, raised timber decks, or commercial yards where the concrete slab extends across the entire area. You can position them precisely, which is harder to guarantee when you’re concreting posts in freehand.
At this price, keeping a few in the van makes sense. You will use them more often than you think, and turning up to a job without them when the customer has a solid concrete base is the kind of thing that adds an unnecessary trip to a day that was already full.
Pro Tip: When bolting to a concrete surface, use an SDS drill with a masonry bit sized to match your anchor bolt, and ensure the shoe base plate is sitting flat before you torque anything up, as even a slight rock will transfer movement into the post over time.
Flush fit bolt down shoes are used wherever a fence or garden post needs to be installed onto an existing hard surface without excavation. Common applications include garden boundary fencing, decorative trellis, pergola uprights, carport posts, and gate posts on concrete driveways or patio slabs. They are regularly specified by fencing contractors and landscapers where the client's existing hard landscaping must remain undisturbed. The 75mm and 100mm sizes cover the most commonly used timber post sections on domestic and light commercial fencing projects.

Fixed to substrate with anchor bolts
Not suitable for: Not suitable for installation into soil, sand, or any unbound surface without a suitable concrete or masonry substrate. Not intended for structural applications requiring engineered post fixings to specific load specifications.
Mark out your post positions accurately before drilling. Hold the shoe in place, mark through the bolt holes, then drill and fit your anchor bolts into the concrete or masonry. Sit the shoe back over the anchors, check it is level, and tighten down. Drop the post into the shoe socket and fix through the pre-drilled holes in the collar using suitable timber screws or bolts.
A spirit level on the post before final tightening will save you time later. If the concrete surface is slightly uneven, a small amount of exterior filler or packing under the base plate will keep things true without weakening the fixing.

What size post does each shoe fit?
The 75mm shoe is designed for 75mm square timber posts and the 100mm shoe is for 100mm square posts. These are the two most common fence post sizes used in domestic and light commercial fencing in the UK.
What anchor bolts should I use to fix the shoe to concrete?
Expanding anchor bolts or resin anchors are both suitable depending on the condition and thickness of your concrete base. For most domestic slabs, M10 expanding anchors at the correct depth for the slab thickness will give a reliable result. Avoid fixings that are too short for the slab depth.
Will the hot-dip galvanising hold up outdoors long term?
Hot-dip galvanising provides significantly better corrosion resistance than standard zinc plating because the coating bonds metallurgically with the steel rather than sitting on top of it. For outdoor fencing applications exposed to rain and seasonal moisture, it is the appropriate finish and should give many years of service without meaningful deterioration.
Constructed from steel with a hot-dip galvanised finish, providing thorough corrosion protection across all surfaces including recesses and edges. The flush base plate design minimises standing water beneath the fitting. Available in 75mm and 100mm socket sizes to suit standard square timber fence posts. Fixing to substrate is via anchor bolts through the base plate, not supplied.
