Bolts are a common type of fastener used to hold things together. They are typically made of metal and have a cylindrical head with a threaded shaft. Here's a breakdown of what bolts typically look like:
Key Components:
- Head: The head of a bolt is the part that you tighten or loosen. It comes in various shapes, including:
- Hexagon: The most common shape, with six flat sides.
- Square: Four flat sides.
- Round: A smooth, rounded head.
- Slotted: A head with a slot for a screwdriver.
- Phillips: A head with a cross-shaped recess for a Phillips screwdriver.
- Shaft: The shaft is the threaded portion of the bolt that extends from the head. It's what screws into the nut or a threaded hole.
- Thread: The thread is a helical pattern cut into the shaft, allowing the bolt to grip and secure the parts it's fastening.
- Point: The end of the shaft may be pointed or rounded.
Examples:
Here are some common examples of bolts you might encounter:
- Hex Head Bolt: A bolt with a hexagonal head, often used in construction and engineering.
- Lag Bolt: A large, heavy-duty bolt with a blunt point, often used for attaching wood to other materials.
- Machine Screw: A smaller bolt with a finer thread, often used for fastening metal components.
- Carriage Bolt: A bolt with a rounded head and a square neck, often used for attaching wood to metal.
