Bolts and their different types


DIC Fasteners is the leading high-quality Manufacturer and Exporter of Bolts in India. We have a variety of Bolts with ready stock for export and supply. Bolts are available in both inches and metric for various industrial applications. We also specialize in stainless steel Hex bolts, Nuts, Stud Bolts, and other types of fasteners.

A Bolt is a mechanical fastener that is usually used with a nut for joining two or more objects together. A bolted joint can be easily put together and taken apart; that is why the bolts or screw fasteners are used to a greater extent than any other type of fastener. The Bolts consist of one head with a cylindrical body with screw threads along with a portion of its length.

Usually, Bolts have more load-bearing capacity than screws; this is the reason bolts are used in most industrial applications. High Tensile Bolts are most important in the development of steel structures because the bolts have more strength. Grades are provided to bolts according to their strength, which is usually stamped on the head of the Bolts. The ordinary type of bolt is the Hex bolt. It has a hexagon-shaped head, which is providing flat surfaces for tools to apply force during its fastening process.

Types of Bolts:

*Anchor Bolts: These Bolts are used to connect structural and non-structural elements to concrete Anchor Bolts prevent separation, lifting, and falling of the objects to which they are fastened.

* Carriage Bolts: Carriage Bolts come with a square neck under their round head. These bolts have a smooth domed head with a square section under which pulls into the material to prevent spinning during its installation.

* Elevator Bolts: These bolts are commonly used in the conveyor system. It has a flat, plain, or countersunk head that holds the bolt in place when tightened.

* Eye Bolts: Eye bolts are externally threaded fastener which is commonly used in various construction works. These bolts are used to lift and transport heavy objects.

* Flange Bolts: Flange Bolts are also known as frame bolts. These bolts can distribute the load by utilizing a washer attached to the underside of the head.

* Hanger Bolts: These Bolts are threaded at both ends with one tip featuring a wood screw point. These bolts are used for overhead applications such as attaching sheet metal.

* Heavy Hex Bolts: These bolts are designed for use in a variety of high-temperature and high-strength industrial applications. They have a wide head than the hex standard hex bolts and it provides a great bearing surface that distributes the clamping load over a wide area.

* Hex Bolts: These types of bolts are used to fasten two or more objects together. They are either fully or partially threaded with a six-sided head at the top of this bolt.

* T Bolts: T Bolts are commonly used to make a bolted joint. These bolts are the same as T nuts in their function. These bolts come in different thread types and lengths for their different applications.

* J Bolts: These bolts are J-shaped bolts that can be used in various industrial applications. These bolts are often used in structural applications like securing walls to concrete foundations.

* Lag Bolts: These bolts are also known as lag screws, they are large wood screws with hexagonal heads, having a sharp cutting thread and shoulder below their head.

* Machine Bolts: Machine bolts are regular hex head or square head bolts, which come with an externally threaded body, used with Nut or a tapped hole.

* Plow Bolts: This type of bolt is commonly used in construction tools and on other devices due to its durability, and is featured by its flat countersunk head.

* Square Bolts: Square bolts mainly consists of a square head equipped with a smooth shank with thread. This head design facilitates its easy grip during its installation.

* Shoulder Bolts: Shoulder bolts are widely used in a variety of applications because of their versatility and unique attributes during installation. These bolts have three main parts: the head, the shoulder, and the thread.

* Structural Bolts: Structural Bolts are often used in structural steel-to-steel fastening applications. It is a hex head style fastener designed to provide the heavy-duty holds needed in the steel building foundation.

* Toggle Bolts: These bolts are also known as butterfly anchor bolts, and are used for hanging objects on unfilled walls like drywall.

* Tap Bolts: Tap bolts are hex head bolts with a fully threaded shank. These bolts can be used in a variety of projects including exterior woodworking.

* U Bolts: U bolt’s shapes are similar to staples, featuring a bent design that creates “U” with partial threading on both ends.
