Bulk 5/8"-5 Hex Lag Screws Stainless Steel 18-8 (A2)

High-Strength, Corrosion-Resistant Fasteners for Demanding Wood Connections

Enhance your toughest woodworking, construction, and outdoor projects with our premium 5/8"-5 Hex Lag Screws.

Made from 18-8 (A2) stainless steel, they offer superior corrosion resistance, ensuring long-lasting performance in challenging environments.

The hex head design allows for easy installation using a wrench or impact driver, while the coarse threads and sharp point ensure maximum grip.
