Bulk 1/2" Hex Lag Screws Stainless Steel 316 (A4)

Marine-Grade, Corrosion-Resistant Fasteners for Demanding Wood Connections

Enhance your marine, chemical, and outdoor projects with our premium 1/2"-6 Hex Lag Screws, made from 316 (A4) stainless steel. These lag screws—often called lag bolts—feature a 1/2" diameter and 6 TPI (threads per inch) coarse threads, providing exceptional holding power in wood and superior corrosion resistance in harsh environments.

The hex head design allows for easy installation using a wrench or impact driver. Their coarse threads and sharp point ensure maximum grip in wood, but remember to pre-drill pilot holes to prevent splitting and ensure proper alignment. These marine-grade screws are ideal for securing beams, building docks or waterfront structures, and other applications where exposure to saltwater, chemicals, or moisture demands top-tier durability.
