Figure 6. Interior wood screws

Lag screws and Lag bolts are two names interchangeably used yet are the same fastener. Lag bolts are the most common term known for the component since the screw appears with a machine thread and a larger size. They are mostly used in applications of wood-to-wood and wood-to-metal and sometimes in concrete. They function in heavy-duty workpieces like connecting hardwood or lumber to other materials. 

Stainless Steel Lag Bolts

Stainless steel is the most prevalent material used in making lag screws. This material offers high corrosion resistance and strength. The common grade for stainless steel lag screws is 304 stainless steel and 18-8 stainless steel.

Hot Galvanized Lag Bolts

The HDG process creates an alloy coating to lag screws. Its purpose is to make steel fasteners highly resistant to corrosion making no room for damage and sustaining a harsh environment of applications.

Zinc Plated Steel Lag Screws

Zinc plating on lag bolts makes a hardened fastener. These screws are less likely resistant to corrosion compared to hot dip galvanized lag bolts but they are ideal for exterior use. 

Silicon Bronze Hex Lag Screws
