Bulk 3/8"-7 Hex Lag Screws Stainless Steel 18-8 (A2)

Robust, Corrosion-Resistant Fasteners for Reliable Wood Connections

Enhance your woodworking, construction, and outdoor projects with our premium 3/8"-7 Hex Lag Screws. With a 3/8" diameter and 7 TPI (threads per inch) coarse threads, these lag screws—often called lag bolts—deliver excellent holding power in wood. Crafted from 18-8 (A2) stainless steel, they provide outstanding corrosion resistance, making them ideal for challenging conditions where durability and stability are essential.

The hex head design allows for easy installation with a wrench or impact driver, while coarse threads and sharp points ensure maximum grip in wood. Remember to pre-drill pilot holes to prevent splitting and ensure proper alignment. These screws are perfect for securing beams, mounting heavy fixtures, or constructing durable outdoor structures.
