I am told there are twenty five different types of nail in anchors available. Each one with a slightly different specialty. They all have different sizes, are made of different and type. They can be anywhere from 25 to 135 millimetres long and between 5 and 8 millimetres in diameter. They can also have either plastic or nylon sleeves.
The two most commonly used anchors are the square rim and countersink. The former is mostly used on sheet metal and other flat surfaces. The countersink anchors are used when you need the nail head to be flush with the surface you are putting it into.
The process involved in inserting this item is fairly easy. You need a drill bit of the appropriate size, a little bigger than the anchor itself, the anchor and the two surfaces you wish to join.
First you need to drill the holes. You can choose to drill a hole into only the supporting surface or into the object as well. This last option usually saves a lot of time and effort. Then you insert the nail in anchor's sleeve. Then it is a simple matter of inserting the nail and hammering it home.
When you are choosing these useful little objects, make sure you choose the right one. Choose one which will be long enough to support the weight of the object you will be fixing to the wall. If it is too short, the weight will cause it to pull out of the wall. Be careful not to get one that is too long though. You do not want to end up drilling into the electrical wiring or plumbing of your home. You can ask for help in choosing the right length and width from the staff at your local DIY store, they should be able to help you choose the right one. You also need to know whether they will be inside the house or outside. Plastic has a tendency to become brittle and break when it is exposed to the elements for long periods of time.
This means that if you intend on hanging something outside, you should opt for those with a nylon sleeve. If you are not sure which one you have got (if you are anything like me, you have a dozen of the things lying in a drawer somewhere and you have no idea what type they actually are) put the sleeve into some water, plastic will float, nylon will sink.
Nail in anchors are very useful things to have around the house as they are easy and efficient to use when hanging mirrors or nailing down skirting boards, so do yourself a favour a go out and buy a few different types to cater for most eventualities and DIY projects.
