When it comes to heavy-duty construction, hex lag screws offer more strength than other wood screws. They’re longer and thicker, making them better suited to support heavy objects. They can also withstand significant stress without breaking or succumbing to damage. This makes them a popular choice for manufacturing companies and construction companies.
In fact, hex lag screws are one of the most durable screw types available. They typically have a galvanized finish, which protects them from rust and corrosion. The outer coating also prevents moisture and oxygen from reaching the lag screw’s underlying steel core, which means they can withstand significant stress and last for decades.
The drawback of hex lag screws is that they require predrilling before use. This is because lag screws are designed to withstand withdrawal and lateral loads. The required predrilling varies depending on the size of the hex lag screw. Lag screws larger than 3/8″ in diameter need to be predrilled with a hole that is two times the fastener’s shaft diameter for shear strength.
Fortunately, there are now hex lag screws with a self-tapping tip that eliminates the need for predrilling. This new technology speeds up installation and cuts down on costs. Its also better for the environment, as it reduces the need for oil-based drilling lubricants and other chemicals. lag screws for wood
