Choosing The Right Plug Size For M8 Coach Screws

When using coach screws, it is important to select the appropriate size of the wall plug to ensure a secure and stable connection. In this regard, the choice of the plug size depends on the specific dimensions of the coach screw, particularly its diameter and length. For instance, an M8 coach screw typically requires an 8mm masonry drill bit, as indicated by sources recommending an 8mm hole for M8 coach screws. Additionally, the type of material being fastened should be considered, as softer materials may require different plug sizes to achieve optimal holding strength.

M8 coach screw and plastic plugs

M8 coach screws are used for fastening wood or masonry. When using M8 coach screws, you will need to use a plastic wall plug, also known as a nylon plug, to fasten the screw into the wall.

The size of the plastic plug will depend on the size of the coach screw and the material you are fixing it to. For an M8 coach screw, a 10mm plastic plug is generally recommended. This means you will need to drill a 10mm hole in the masonry for the plug to fit.

It is important to note that if the hole is too big, the plug will rotate and be difficult to stop from turning. It is always a good idea to have some spare plugs in case of any issues.

There are alternative options to using plastic plugs, such as using concrete screws that can be drilled directly into the brickwork or using thunderbolts, which are the coach screws of concrete and masonry and do not require any plugs.

M8 coach screw and masonry

M8 coach screws are heavy-duty wood screws used in masonry applications. When using coach screws for masonry, it is essential to use a suitable plug and drill a pilot hole to ensure secure fixation.

For M8 coach screws, the recommended plug size is a 10mm nylon plug. Nylon plugs are designed to expand in the hole, providing a tight and secure fit for the screw. When using a nylon plug with an M8 coach screw, it is crucial to drill a pilot hole with the appropriate diameter. The recommended hole size for an M8 coach screw is 8mm.

It is important to ensure that the hole is drilled to the correct depth, matching the length of the plug and screw. Drilling a hole that is too large can cause the plug to rotate and make it difficult to stop it from turning. Therefore, it is advisable to use the correct drill bit size and apply caution when drilling to avoid drilling a hole that is too big.

When using M8 coach screws with nylon plugs in masonry, it is also essential to consider the type of masonry material. For softer blockwork or masonry, specialised plugs like SX plugs may be more suitable as they are less prone to rotating before they bite and expand. These plugs expand in four directions, providing a more secure hold in softer materials.

Additionally, it is worth noting that there are alternative fixing methods for masonry, such as Thunderbolts, which are considered the "coach screws of concrete and masonry." Thunderbolts do not require plugs and can be directly drilled and screwed into concrete or masonry, offering a more straightforward installation process.
