Types of Bolts and Their Uses

 

A bolt is a form of fastener used to connect two parts. The bolts join the parts in a non-permanent manner, allowing the parts to be separated using an appropriate tool.

A bolt is made up of three parts, which are

1. Head: The upper portion of the bolt is referred to as the "head." The shape of the head can vary. The shape of the head is determined by the purpose of the bolt.

2. Shank: The shank is the cylindrical portion of the bolt. The bolt's tail end is threaded to a sufficient length for a nut to be engaged on it. In addition, the shank's end is clipped to facilitate inserting a hole and a nut on it.

3. Threading:  Threading is present on all bolts. Threading is the movement of a bolt into or out of a work piece. Most bolts, however, do not have complete threading. They have a smooth leg ahead of them, followed by threading. The shank may cover a larger surface area than the thread depending on the type of bolt. All bolts, however, have threading.

To join them, the threading of a bolt works with the internal threading of the workpiece. External threading is located outside the bolts' bottommost part. This allows the external threading bolt to be moved into or out of the work piece’s internal threading.

 

Bolt types include:

Bolts are one of the most versatile structural fasteners, with a wide range of configurations to suit various materials and strength requirements. 

 Bolts are classified into various types based on their unique head shapes, strengths, finishes, and materials.

Some of the prominent ones are:

Stud bolts:

A threaded rod, also known as a stud bolt, is a long rod that is threaded on both ends; the thread may extend the entire length of the rod. They are externally threaded fasteners without a head that are used with two nuts on either side to replace a traditional bolt and nut combination. Flange connectors frequently employ stud bolts.

Hex fit bolt:

Hex bolts have a six-sided hexagonal-shaped head and are a type of threaded bolt. Hex bolts come in two types: fully threaded and partially threaded (with a clear shank along part of the body) and can be used in a variety of applications, including machinery and construction.

They come in a variety of types, sizes, materials, and finishes, giving you the freedom and flexibility to choose the finest bolt for your task or application. Due to their unusual head form, hex bolts are also known as hex head bolts or hexagon bolts.

Cylinder head bolts:

Bolts that fasten an engine's cylinder heads to the engine block are known as cylinder head bolts. They serve as a link between the engine block, the cylinder head gasket, and the cylinder head.

The bolt tightening force is critical for the mutual sealing of the combustion chamber, lubrication and coolant channels, and the ambient air. A job that necessitates flawless execution with cold or extremely hot engines, as well as negative and positive pressures.

The bolt force provides the so-called surface pressure when tightening (torqueing) the cylinder-head bolts, which is necessary for achieving a flawless seal. Bolts have a significant impact on surface pressure quality when used in conjunction with the torqueing method.

Shoulder bolts:

Shoulder bolts are screws that are divided into three parts: the head, the unthreaded shoulder, and the threads. Integral threads are present on half or less of the screw shank, with the remaining shaft expanded and smooth to allow the bolted material to spin or move around the screw axis. 

Shoulder screws, like all other screws, are designed to hold items together and in a specific location. These screws, on the other hand, are intended for parts that require a mounting pin, joint, shaft, dowel, pivot, or sliding motion.

Things like: bearings, machine assistance, precision spacing, motion guiding, etc.

Banjo bolt:

A banjo bolt is a component of a banjo fitting. Pressurized fluid is frequently passed through banjo fittings. They're most commonly seen in motorcycle brake systems, but this type of fluid-transfer fitting has a wide range of non-motorcycle applications.

A banjo bolt is a hollow bolt with a hole on one side. This hole allows fluid to flow into the fitting's other half, which is also hollow.
