What is Hexagonal Bolt? Uses, Dimensions and Types

Hexagonal Bolt

Hexagonal bolts are an essential part of modern construction and engineering. From small-scale DIY projects to large-scale industrial installations, hexagonal bolts are a must-have for any job. But what exactly is a hexagonal bolt, and how can you use it effectively? Keep reading to find out!

What is Hexagonal Bolt?

A hexagonal bolt is a fastener with an external six-sided head and internal threading. The most common type of hexagonal bolt is the carriage bolt, which has a round shaft with threads that taper off at the end. This helps keep the bolt in place when tightened into its nut or other receiving material. Other types of hexagonal bolts include lag bolts, machine screws, and structural bolts.

Hexagonal Bolts Uses

Hexagonal bolts have a variety of uses depending on their size and design. Smaller hexagons are used to hold together furniture or machinery, while larger ones are used to secure heavy loads in construction projects or industrial installations. Hexagons also come in different materials such as steel, stainless steel, brass, aluminium, and bronze which makes them suitable for both indoor and outdoor use.

Hexagon Bolts Types

There are many types of hexagon bolts available for different kinds of applications. Carriage bolts are the most common type used for general-purpose applications, while lag screws provide superior holding power for heavier loads in woodworking projects. Structural bolts offer increased strength for larger projects such as bridges or buildings, while machine screws can be used to securely fasten two separate objects together without needing additional nuts or washers for support.
