Fixman 995311 Bolt Down Post Shoe 75 x 75 mm

Product Information

This is probably the strongest method of fixing, especially in concrete which has been mixed by hand and may contain air bubbles. This allows you to hit the spike as firmly as you like without the risk of bending the sides of the post holder, which would prevent you slotting the post into the holder. On a concrete surface we suggest you bolt it down using Rawl bolts (shown below) which are placed into holes drilled into the concrete and then tightened.

Our selection of heavy-duty post shoes weighs between 2kg and 3.4kg. These are far superior to standard post shoes, making them best suited for heavy-duty applications. Some of our best-selling heavy-duty post shoes include 100mm x 100mm Heavy Duty Self-Colour Post Shoe Type 4, 100mm x 100mm Heavy Duty Stainless Steel Post Shoe Type 4 and 150mm x 150mm Heavy Duty Galvanised Post Shoe Type 4. These are bolt down post supports that will require four base fixings, such as M12 concrete anchors. Do not use the shorter post holders for tall fences, they’re simply not up to teh job and as soon as they are subjected to any substantial wind they will likely fail. 50x50mm Post HoldersYou can also buy post holders that are designed to be concreted in to the ground. They are made of steel and are extremely hard-wearing and resistant to corrosion due to the fact they are dual coated – firstly zinc plated then powder coated. See also “What Size Fence Spike do I need?” above and treat the four-finned product as if it was the longer spike. Fence Post Repair Spike It is also ideal for fixing signposts – again this is the size used by estate agents for their signs. Use the longer length in light sandy soils or for taller posts – higher than 4 feet (1.2M). 75x75mm Post Holders With the rawl bolt, as the head of the bolt is tightened the bottom sheath expands, gripping the concrete.

Chain link fencing for example, puts a lot of stress on the posts as it is tightened and the post holders would not be secured strongly enough in the ground for this (more on this can be found in our project on Chain Link Fencing). Bolt Down Fence Post Holder The “shoe” should be set into a 450mm (18 inch) cube of concrete so that the base plate sits flush with the surface of the concrete. For years Metpost or post spikes have been the biggest supplier of fence post holders, or post spikes, but now there is much more of a choice with other manufacturers producing similar products. Fence Post Metal Spike It is worth noting that these post holders also need to be level, so if you are fixing them to a base that has a slope or a dip then you can insert washers beneath the post holder holes to line up small disparities.This size would be best for fences in exposed areas, long expanse of fencing, gazebos which will be supporting a roof and pergolas if you want a more chunky-looking timber structure. Concrete-in fence post holders are designed for use where soil conditions are unsuitable for drive-in spikes. Note: Remember to ensure that you keep the post holder totally level as you drive it down into the ground – more on this below Once the spike is driven into the ground, the driving tool can be removed and the post pushed into the holder. There is a bolt on the side of the holder that can be done up easily with a spanner to keep the post firm in the spike.
