Here's how to choose the right nail

Extraction load: At excretion load, the forces will pull the nail out. To counteract it, you can tickle. .

You only need a hammer, and maybe some knowledge about how to use it, so you’re up and running.

Do not drop compressors, nail guns or screwdrivers that run out of battery power.

Two types of load

Choosing the right nail is about choosing the right type, size and nailing it right.

It’s ok to know that nails are subjected to two types of stresses: cross-strain and pull-out load.

transverse loads

Cross-strain is the forces that work across the nail. If the nail is exposed to cross-strain, a straight rule is that the nail should have an anchorage length of 2/3 of the entire length.

Extracts Strain

Extraction strain is the forces that pull the nail out, like when you have attached a nail to the roof.

If the nail is exposed to tensile stress, it is good to know that the resistance here is quite small. In addition, it is greatly reduced by large moisture variations.

To increase the extraction capacity, you can cross-point or use what is called the nail comb.

Nail Types and Where You Use them

Square nail is the most common nail worker’s nail. It usually uses you to combine three

Dive nail is a square nail head with a little head. It is suitable for work where the nail head is to be sunk so that it does not seem.

Double-headed styling nails is like square nails but has two heads. It is used for temporary attachments, such as when creating a formwork so that it can be retracted.

Steel nail is made of hardened steel so it does not bend just as easily as normal nails. It is intended for nailing in walls and concrete.

Daddy’s is a short nail with wide flat head so that the folder is held in place.

Kamspiker is a nail fitted with grooves to increase the extraction capacity. It is usually short and thick, and is used for fixing nails and fittings.

Gypsum plaster is used to mount plasterboard.

Terrace nail is used to attach decking.

How big?

Nails come in three varieties, round, square and sharp edges.

The dimension usually indicates the thickness and length in millimeters. For example 2.8 x 75. Then it’s a nail that is 2.8 millimeters thick and 75 millimeters long.

Surface treatment and applications

White nails are made of untreated steel and are only suitable for dry, hidden places.

Elongated nails are coated with a thin zinc layer that protects against rust. They are to be used for internal work so that there is no rust proof on eg painted moldings.

Hot-dip galvanized nails have good rust protection and are used in wet rooms and outside. The zinc coating also means that these nails are better than other nails.

Painted nails are used when mounting painted moldings and plastic coated sheets.

What do you do when it breaks?

Try a thinner nail.

Nestling near the end is also the table prone to cracking. Try a little further in.

You can also get lost. Make the hole slightly smaller than the nail thickness.

One last tip is to pinch the tip or knock it flat.
