Lag bolt
Lag Bolt
A Lag Bolt or lag screw is a type of fastener used in woodworking and construction industries. It is designed for securely connecting heavy lumber or other materials that bear an intense load.
Design and Function[edit | edit source]
The Lag Bolt is characterized by a large, hexagonal head and a coarse thread that covers a portion of the bolt. The design of the lag bolt is such that it can be driven into wood or other materials with the use of a wrench or a screwdriver. The coarse thread is designed to hold tightly into the receiving wood, providing a secure, tight connection.
Applications[edit | edit source]
Lag Bolts are commonly used in applications where heavy loads need to be secured. This includes the construction of decks, wooden bridges, and other heavy-duty structures. They are also used in the installation of heavy equipment, such as electrical utility poles and large machinery.
Types of Lag Bolts[edit | edit source]
There are several types of Lag Bolts, each designed for a specific application. These include:
- Stainless Steel Lag Bolts: These are used in applications where corrosion resistance is important. They are often used in outdoor applications, such as in the construction of decks and marine structures.
- Galvanized Lag Bolts: These are coated with a layer of zinc to provide corrosion resistance. They are commonly used in outdoor applications where they may be exposed to the elements.
- Structural Lag Bolts: These are designed for use in structural applications, such as in the construction of buildings and bridges. They are typically larger and stronger than other types of lag bolts.
Installation[edit | edit source]
Installation of a Lag Bolt involves drilling a pilot hole into the receiving material. The bolt is then driven into the hole using a wrench or a screwdriver. The size of the pilot hole is typically slightly smaller than the diameter of the bolt to ensure a tight fit.
