Heavy-Duty Hex Head Lag Screws for Robust Construction

Hex head lag screws, also known as lag bolts, are robust fasteners used for heavy-duty wood construction. With a hexagonal head designed to be driven by a wrench or socket, these screws offer high torque application, which is essential for pulling thick, dense materials tightly together. They are ideal for heavy-duty connections that may not be adequately supported by typical wood screws or timber screws. The deep, coarse threads are specifically engineered to grip wooden substrates securely, ensuring a lasting hold in both indoor and outdoor applications, from framing to deck building.
The practical design of hex head lag screws – also available in flange hex head styles - allows them to function as both a screw and a bolt, offering the best of both worlds in terms of easy installation with a wrench and holding power. They are essential for creating joints with exceptional strength and stability in structural applications. When used properly, these screws distribute stress over a wide area, reducing the likelihood of material splitting while offering superior clamping force. This makes them ideal for attaching heavy lumber or other substantial materials.
  • High Torque Application: Their robust nature ensures tight assembly in heavy-duty environments.
  • Durable Construction: These screws are available in stainless steel and low carbon steel with hot-dipped galvanized, plain, or zinc clear finishes to offer superior durability and specified corrosion resistant options.
  • Enhanced Safety: They offer reliable performance in critical structural applications.

Hex Head Lag Screw Installation Best Practices

It is important to pre-drill a hole for the screw so the wood does not split, and to ensure that the hole is sized correctly to facilitate a proper hold. Additionally, make sure you are using the right installation tool to prevent stripping or overtightening.
