Nuts are made of the same material as bolts and screws and can have the same kind of plating.
Precise bolt-and-nut joints can only be achieved when they are made of the same materials, grade of material and have the same type of coating.
Used in structural steel engineering and mechanical engineering. There are hexagon nuts of different sizes of ISO metric coarse and fine threads and of flat or wide shape. The cap nut is a special design. Cap nuts provide caps on bolted or screwed joints. They are used as a safety precaution or for better looks. Cap nuts keep the thread clean.
1 hexagon nut, 2 cap nut
Knurled nuts and wing nuts
Used for producing detachable joints of component parts by hand, without the use of tools.
1 knurled nut, 2 wing nut
Slotted nuts and nuts with two holes
These nuts are used mainly for electrical components where space is limited and the joint is not easily accessible.
