Types of Nuts and Bolts Commonly Used in Construction in India

Every construction project requires nuts and bolts, which are fundamental to the stability and safety of the structure. These fasteners have many different varieties, each with unique features and specifications.

It’s essential to have a solid understanding of the numerous kinds of nuts and bolts frequently used in buildings in India since it’s a sector with rapid growth. You can save time and money by knowing which fastener to use for a specific project while ensuring that it is constructed to the highest possible levels of quality and safety. 

In this blog, we’ll look at some of the nuts and bolts that are most frequently utilized for various applications. 

Nuts & Bolts Use 

Mechanical fasteners like nuts and bolts are used to connect multiple objects tightly. They are extensively utilized in the manufacturing, automotive, aerospace, and construction sectors. These fasteners are available in various shapes, sizes, and materials. 

For the linked components to be safe and durable, nuts and bolts must be appropriately chosen and installed. They can be used in permanent and temporary connections and offer a sturdy connection that can withstand significant forces and vibrations.

Types of bolts

Hexagonal Bolt 

Also referred to as a hex bolt, this fastener features a six-sided head. It is also frequently employed in the automotive and construction sectors. A spanner or socket is needed to tighten it.

Square Head Bolt 

This fastener’s square-shaped head is frequently employed for applications that need more force to be exerted. Along with being frequently utilized in equipment and industrial building, it is also used in woodworking applications.

Carriage Bolt 

These fasteners have a square or hexagonal shank and a smooth, dome-shaped head. Usually, these bolts attach metal or wood to another object. They are also referred to as coach bolts.

Round Head or Cup Bolt 

These fasteners are the best choice for applications where the bolt will be subjected to strong loads or where the surface being connected is soft or easily damaged because of its round head design.

T- Square Head Bolt 

These fasteners are used for assembling machinery and equipment and building applications. Its wide head creates a sizable gripping surface that can be used for tightening or loosening. 

J – Bolt 

They have a J-shaped hook on one end and a threaded shaft on the other. These are mainly used to secure poles and pipes to walls, ceilings, or similar surfaces.

U-Bolt 

They have a U-shape and two threaded arms that extend from a curved base. The threaded arms attach the bolt to an object by wrapping around it and securing it with a nut. 

Eye Bolt 

These fasteners have a loop or eye-shaped head that allows ropes, cables, or chains to be attached easily. They can be inserted into a pre-drilled hole or attached to a surface with a nut.

Shoulder Bolt 

These are also known as a stripper or shoulder screws. They have a cylindrical shoulder that allows for precise axial positioning of the attached object. 

Cylindrical Head Bolt 

Also known as round-head bolts, these fasteners have smooth and rounded heads with a flat bearing surface. These are typically larger than the thread diameter and provide a large contact area for distributing loads. 

Elevator Bolt

They have a flat, countersunk head and a square neck that prevents the bolt from turning when tightened. These are used to attach conveyor belts to equipment or to secure wooden components in construction.

Hanger Bolt 

They have a threaded end on one side and a wood screw thread on the other. They are used to attach objects to wooden surfaces or to join two pieces of wood together, which makes them perfect for furniture and cabinetry.

Lag Bolt 

They have a hexagonal head and a sharp, pointed tip designed to drill into wood or other materials. They attach heavy objects to wood, such as decks, fences, and furniture.

Types of Nuts

Hexagonal Nut 

Also known as hex or six-sided nuts, they have six sides, and the corners are chamfered to provide easier installation and prevent damage to the surrounding material. These are available in different materials, such as steel, stainless steel, brass, and nylon.

Square Nut 

They have four sides and are frequently used with square-shanked bolts and screws. They are employed when more torque is needed, including in the construction, automotive, and industrial industries.

Cap Nut 

 Also known as acorn nuts, they have a domed top covering the bolt’s end or screw. They are commonly used for aesthetic purposes or to provide a smooth finish to the exposed end of the fastener.

Flange Nut

They have a broad, flat base that gives the weight more equitable distribution by providing a more excellent bearing surface. They are frequently utilized in industrial and automotive settings where vibration and stress are present.

Dome Nut 

They have a rounded top that gives the fastener a finished look. They are frequently used in ornamental applications like handrails, furniture, and lighting.

Capstan Nut 

Also known as knurled cap nuts or hand knobs, they have a broad, knurled head that offers a firm grip for hand-tightening and are. These are frequently used in applications that need frequent adjustments or removals.

Ring Nut 

They have a ring around the outside that is a safe attachment point for chains, ropes, or cables. They are frequently used in outdoor and marine settings, rigging, and lifting applications.

Knurled Nut 

For hand-tightening, they have a textured surface that offers a firm grip. These are frequently employed in settings that require regular adjustments, like machinery, equipment, and electronics.

Thumb Nut 

Also known as butterfly nuts, they have a wing-shaped head that offers a solid grip for hand-tightening without using tools. 

Wing Nut:

They have two extensions in the shape of wings that offer a firm grip for manual tightening without equipment. They are used on fixtures, equipment, and toys.
