Hex Head Lag Screws

• Use a bit having a slightly smaller diameter than the selected lag screw and drill a pilot hole all the way through the surface.
• Use a ratchet, nut driver or power drill with the right driver bit to install the hex head lag screw.

It is highly recommended to use washers with lag bolts. Using a washer under the screw head increases the surface area in contact with the application surface. This decreases chances of the screw head digging into the surface and cracking it due to heavy load.

• Wood screws are used to connect only wooden materials whereas hex head lag screws can be used to join wooden materials with other materials as well.
• Wood screws do not require pilot holes as they thread into the surface, but lag screws require a pre-drilled hole.
• Lag screws can handle heavier loads than wood screws.

Hex head lag screws adhere to international standards like ASME, ASTM, SAE & DIN for meeting performance, safety, dimensional & material requirements.
