Lag Bolts

What Are Lag Bolts?

Lag bolts are exceptionally strong bolts with a hex head. They’re generally used to connect heavy lumber or other materials which bear an intense load. More info

When selecting a lag bolt, always measure the materials being joined. The length of the lag bolt should not be more than half of the total thickness of the materials.

Features of a Lag Bolt

• 1. Lag Screws are heavy duty wood screws with strength and durability that keep them in place in high-stress environments.
• 2. The hex head is designed for use with a wrench, ratchet, or impact driver to accommodate higher installation torque.
• 3. As with wood screws, a stepped pilot hole is recommended. The pilot hole for the unthreaded shank should match the diameter of the screw, and the hole size for the threaded portion is dependent on wood density.

Frequently Asked Questions About Lag Bolt Screws

What is the purpose of a lag bolt?

Lag screws are used for woodworking in instances where the attached segments are fairly beefy and where a lot of holding power is required.

Do lag bolts hold better than screws?

It depends on your application. Lag screws for wood work well for bulky projects, but some other types of wood screws have similar holding power and are better suited to more delicate applications.

Which materials are lag bolts usually made of?

Lag bolts typically consist of galvanized steel, stainless steel 316, or stainless steel 18-8.
