Types of Bolts - A Best Buying Guide
 

Introduction

Fasteners like nuts and bolts are the building blocks of many machines. A bolt and nut are two parts of a fastening system that share the name "threaded screw." The nut and bolt need to be the same size for them to work together. In addition, the type of bolt, its physical dimensions, its thread density, and its tightening are all vital features for a secure assembly.
 

Types of Bolts 
 

1. Galvanized nut bolts

After production, they are often dipped in several chemical baths to ensure a uniform and robust finish. These bolts are ideal for use in the outdoors, and particularly in coastal areas due to the thickness of the coating, which provides good corrosion protection.
 

2. Stainless Steel Bolts 

These fasteners are great for use in areas with high concentrations of salt water and chlorine because of their exceptional resistance to corrosion.
 

3. Hardened Steel Bolts 

Due to their superior durability, they find widespread use in automobile components and assemblies. They are constructed using a steel alloy that is mostly composed of copper and zinc.

Buying Guide 
 

1. Choosing the right material 

Remember that a bolt manufactured of better material may not certainly be the ideal selection for all kinds of applications. For example, thick metal bolts that give higher strength are not suited in saltwater and chlorine conditions. Instead, material with resistance grades with anti-corrosive qualities is recommended for such applications
 

2. Choosing the correct bolt size 

Determining both the length and the diameter of every bolt is vital before using it. The diameter is found by gauging the distance between two adjacent outside threads on opposite sides. Choosing the improper bolt size might result in abuse of the materials, wasting of time and effort in completing an assignment or work.
 

3. Choosing the right bolt type

There are many of possibilities to choose from when you start to look for bolt types, rendering the choosing more tough and complex. Also, several bolts that offer maximum stiffness when applied to particular materials may not provide equal strength for other materials. Therefore, choosing the proper bolt type according on your usage is vital for seamless installation.

Overview: Bolts
 

A bolt is a type of mechanical fastener used in conjunction with a nut to secure a connection between two or more components. Because of the ease with which a bolted joint may be disassembled and reassembled, bolts and screw fasteners are more commonly employed than any other form of mechanical fastener and have been instrumental in the evolution of mass-produced goods and steel structures.

The bolt features a threaded section along its length and a cylindrical body connected to the head. The nut is the female half of the fastener and features threads on the inside that correspond to the bolt. It is common practice to utilize washers in order to avoid loosening and crushing. For related terms, see nut and washer.

Types of Bolts
 

1. Carriage bolt

Carriage bolts have a squared-off bottom and a dome or countersunk head to prevent them from working after installation. As such, they are frequently applied to wooden and brick structures.
 

2. Flange Bolt

Flange bolts are a variant on the standard hex head fastener; the flange serves as a washer to disperse pressure across the bolt's threads.
 

3. Hull Bolts

Some hull bolts have a squared-off counter top, much like carriage bolts. Other examples feature a dome shape. When it comes to industrial machinery or other heavy-duty uses, these bolts are your best bet.
 

4. Hex head bolt 

A wide variety of bolts having a hexagonal head are referred to together as hex head bolts. They come in a wide range of lengths and can be threaded in various ways. The most often used type of hex bolt is the hex head cap screw, which features a particularly high tolerance.
 

5. Square Head bolt

As the name implies, square head bolts have square heads, as opposed to the hexagonal heads of hex head bolts. The shape of the head makes it easier to get a firm hold with tools, and the design also makes it simple to set up.
 

6. Socket head cap Bolt

The top of the socket head cap screw is flat and chamfered, while the cylindrical sides are smooth or curved. Some examples of high-strength fasteners made from specific alloy aggregates are forged and heat-treated alloys designed for the most rigorous mechanical applications.
 

7. Cylindrical Bolt

These fasteners are sometimes referred to as cheese head bolts due to the cylindrical shape of the head.
 

8. Shoulder Bolt

The pivot is made out of shoulder bolts, which are also known as stripper bolts.
 

9. U-Shaped bolts

This U-shaped bolt is ideal for joining spherical objects such as pipes together. It also manifests as a square band.
 

10. Eye Bolt 

The top of this bolt has a circular ring, indicating that it is a bolt. To facilitate the lifting of the machine's massive frames, eye bolts are installed.
 

11. T-Shaped Bolt

The common application for this style of bolt is to secure a job or workpiece to a table, as its head resembles the letter "T" in English.
