Carriage Bolt
1. Descriptions:
carriage bolt, also known as a coach bolt or round head square neck
bolt, is a type of threaded fastener with a distinctive domed head
and a square or rectangular shoulder section just below the head.
Carriage bolts are typically used to fasten wood or metal
components together. Here is a description of a carriage bolt:
Construction: Carriage bolts are usually made of steel, stainless
steel, or other alloy materials. They consist of three main parts:
a round, domed head with a smooth, slightly curved top surface; a
threaded shank that extends from the head; and a square or
rectangular shoulder section located directly below the head.
Head Design: The domed head of a carriage bolt is typically larger
in diameter than the threaded shank. It provides a smooth, finished
appearance and offers a bearing surface when installed. The top
surface of the head is usually flat or slightly rounded, making it
suitable for applications where a flush or low-profile finish is
desired.
Square Neck: One distinctive feature of a carriage bolt is the
square or rectangular neck section just below the head. The square
neck is designed to fit into a corresponding square hole or slot in
the material being fastened, preventing the bolt from rotating
during installation. This feature allows for easy one-person
installation, as the bolt can be held in place while the nut is
tightened on the threaded end.
Threaded Shank: The threaded shank of a carriage bolt extends from
the head and is used to secure the bolt in place. The threads on
the shank are typically coarse, allowing for quick and easy
installation into pre-drilled or pre-tapped holes.
Applications: Carriage bolts are commonly used in woodworking,
construction, and other applications where a secure joint is
needed. They are frequently used to fasten wood components, such as
building structures, fences, decks, and furniture. Carriage bolts
can also be used in metal-to-metal applications, such as securing
brackets or plates.
Installation: To install a carriage bolt, a hole is first drilled
into the material being fastened. The square neck of the bolt is
then inserted into the corresponding square hole or slot. The bolt
is held in place while a wrench or socket is used to tighten a nut
onto the threaded end of the bolt, securing the joint.
Carriage bolts are valued for their strength, ease of installation,
and aesthetic appeal. Their unique design makes them suitable for
applications where a secure and visually pleasing fastening
solution is required.
