A bolt consists of a head which allows the accessibility to be driven or turned. The tools that are mainly used for driving these bolts are wrenches and screwdrivers. The head of the bolt is larger than the body which helps the bolt to drive deeper than its length so that the bearing surface is provided. Nuts are used in matching bolt’s opposite to fasten tightly the stack of parts together. The nut and the bolt are kept together by a coupling of their friction of threads, compression of the parts and the bolt’s slight stretching.
The applications that involve rotation or vibration can make the nut loose from the bolt so different locking mechanism are applied like lock wire or safety pins, adhesives, oval shaped threads or nylon inserts. The most common shape of nut bolt is hexagonal which consists of 6 sides that offers better granularity of angles and the approach for the tools become easier. Smaller corners with rounded off edges becomes vulnerable for the tools to operate.
Brass is preferred for nuts and bolts because brass consists of acoustic and malleability properties. Brass has higher malleability than any other metal like zinc or bronze. It possesses flow features with low melting point which makes easier to cast. Brass is also recyclable. It is not ferromagnetic so brass is easily separable with the help of a magnet from the ferrous scraps. Brass is resistant to corrosion and stronger because of the aluminum present in it. A hard layer of aluminum oxide is formed on the surface which is self healing and transparent.
Brass is resistant to all types of wear and tear which also allows to be used in sea water applications. Brass is resistant to all types of harsh environments like applications used in water boiler systems and in high water temperatures. Brass also possesses germicidal and antimicrobial properties. Microorganisms are killed within a few minutes to hours of being touched by brass depending upon the concentration and type of pathogens.
All types of nuts and bolt of brass are available online. Persons interested in purchasing these nuts and bolts can browse the various official websites of the manufacturers.
