What Makes a Lag Screw the Strongest Wood Screw?

The Strength of Lag Screws

A lag screw is the strongest member of the family of wood screws due to its design and construction. Lag screws, also known as lag bolts, are heavy-duty fasteners that are commonly used when heavy load-carrying capabilities are required. These screws have robust and durable construction, which sets them apart from standard wood screws.

Key Features of Lag Screws

Lag screws are characterized by their large size, coarse threads, and tapered points. These features contribute to the exceptional strength and holding power of lag screws. The coarse threads on lag screws are designed to grip into wood effectively, providing a secure hold even under significant pressure and weight.

Comparing Lag Screws to Standard Wood Screws

When compared to standard wood screws, lag screws are significantly stronger and heavier. This strength makes them ideal for applications where stability and strength are paramount, such as in construction projects or heavy-duty woodworking.

Applications of Lag Screws

Lag screws are commonly used in structural applications, such as securing beams, trusses, and ledgers. Their unparalleled strength and holding power make them the preferred choice for projects where safety and reliability are crucial.
