Though, they come in small sizes and shapes nuts and bolts are absolutely indispensable when it comes to attaching or fixing the various machinery parts. They are defined as a kind of fastener that act as a locking mechanism to ensure that there is no loose parts in your machine, whether in automobiles or in any manufacturing large units. While in general all types of nuts and bolts look the same, they serve diverse purposes which are determined from their types.

The Types of Nuts and Bolts

Nuts and bolts appear in varied types and each one of them is designed to meet specific purpose. The three determining factors like diameter, thread count and pitch separate the size and purpose of nuts and bolts from each other. Once you have chosen specific nut and bolt, you have to consider the pitch, length and diameter and whether they are apt to fit for the right objective. Herein, we offer you instructions on how to determine the types of nuts and bolts.

Useful Instructions

First, lay the bolt on a flat surface. Then you may use a magnet to determine whether the nuts and bolts are made of stainless steel or just steel. You can know this if the nut and bolt sticks to the magnet then it is made of steel, otherwise the nut and bolt is made out of stainless steel or any other types of metal.

There are three different grades for bolts- grade 2, 5 and 8. A grade 2 bolt always has six-sided head and is devoid of any markings on the top. Yet again, the grade 5 bolt also has six-sided head along with three lines etched right on the top of bolt head. Also, a grade 8 bolt also has six sided head and six lines grooved on the top of the head.

Count the number of pitches that signify the number of threads on the bolts.

Use a measuring tape to measure the diameter of the bolt. Remember, the diameter indicates the width of the threads.

Yet again, you should measure the size of the bolt from the exact point of its bolt head to the end of it.

The measurements that you have noted so far will help you determine the diameter, length and pitch count of bolts. For instance, if the numbers are ¼ inch, 11/2 inches and 20 inches; then this means that the diameter of the bolt is ¼ inch, the length is 11/2 inches and the pitch is 20 inches.

Also, there are specific ways of determining the type of nuts. You can do this by determining the height and diameter of nut. The diameter is explained by measuring the inside width of the nut and the height of the nut is determined from the total length from the bottom.
