Lag bolts are often referred to as lag screws. Lag bolts are not like other bolts. They look like a screw rather than a bolt with their pointed end instead of the more common blunt end found on most bolts.
Lag bolts or lag screws may be made out of steel, stainless steel, or silicon bronze, and can be hot-dip galvanized to accommodate any and all projects as needed. Mostly used in the construction field, lag bolts are also commonly used for a variety of projects in and out of the home.
Lag bolts are made from a variety of materials to accommodate the abundance of applications in which lag bolts are used. Below are some of the more common styles of lag bolts and lag screws.
Common Types of Lag Bolts / Screws
Zinc-plated lag bolts/lag screws: Moderate protection against rust.
Stainless steel 18-8 lag bolts/lag screws: With high corrosion resistance, stainless steel is the material of choice for lag bolts in exterior and marine applications.
Silicone bronze lag bolts/lag screws: Used in wood boat building this alloy of copper has better strength and corrosion resistance than brass.
Hot dipped galvanized lag bolts/lag screws: Much more corrosion resistant than zinc-plated. These thick coated lag bolts with galvanized butts are ideal for exterior use in coastal areas.
