Products Description

Also known as a coach screw in the UK, a lag screw is basically a big metal screw with a hexagonal head. It's made for tough jobs where there's a lot of stress. Lag screws are longer and thicker, they're super strong and last a long time. That makes them perfect for woodworking when you need to join heavy stuff together. A lag screw features a high-carbon steel core with a galvanized zinc exterior. The presence of the galvanized zinc protects the law screw's underlying steel core for rust and corrosion. Moisture and oxygen can't easily penetrate galvanized zinc, so lag screws generally don't rust or corrode.

The name "lag screw" comes from their original use - securing wooden lags. These screws can handle a ton of stress without breaking or getting damaged. That's why lots of manufacturing and construction companies use them to join heavy objects. Since they're bigger and stronger than other screws, they perform better. They stay put even under the weight of heavy stuff, thanks to their strength and durability.

Pilot Holes

For larger lag screws, it is recommended to pre-drill (create pilot holes) to prevent wood from splitting, especially in hardwoods or near the end of pieces.

Torque Specification

Use appropriate torque when tightening to avoid stripping the wood or damaging the screws.

Consider Wood Type

Choose the length and diameter based on the material and application, ensuring adequate holding power while mitigating the risk of damage to the surrounding wood.

Corrosion Resistance

For outdoor or moist environments, use lag screws made from corrosion-resistant materials or treated with appropriate finishes.
