A bolt is a type of fastener with a hexagonal head and a threaded shaft.
Anatomy of a Bolt
Here's a breakdown of the key components:
- Head: The top part of the bolt, usually hexagonal or square-shaped, allowing for tightening with a wrench.
- Shaft: The cylindrical body of the bolt, extending from the head to the tip.
- Threads: Helical ridges cut into the shaft, allowing the bolt to engage with a nut or threaded hole.
- Tip: The pointed or rounded end of the bolt, designed to fit into a hole.
Types of Bolts
Bolts come in various types, each suited for specific applications:
- Hex Head Bolts: The most common type, with a hexagonal head for easy tightening.
- Square Head Bolts: Feature a square head, often used in applications where a hexagonal head might interfere.
- Flange Bolts: Have a wide, flat head with a flange that provides a larger bearing surface, distributing the load more evenly.
- Carriage Bolts: Designed with a rounded head and a square or hexagonal underside, commonly used in wood construction.
Visualizing a Bolt
Imagine a metal rod with a hexagon-shaped cap on one end. The rod is covered with spiral ridges, similar to a screw. This is the basic structure of a bolt.
