Bulk 1/4"-10 Hex Lag Screws Stainless Steel 316 (A4)

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

Enhance your marine, chemical, and outdoor projects with our premium 1/4"-10 Hex Lag Screws, crafted from 316 (A4) stainless steel. These lag screws—often called lag bolts—have a 1/4" diameter and 10 TPI (threads per inch), offering excellent holding power in wood and superior corrosion resistance for harsh environments.

The hex head design allows for easy installation using a wrench or impact driver, and the coarse threads and sharp point ensure maximum grip in wood. Pre-drill pilot holes to prevent splitting and ensure proper alignment. These marine-grade screws are ideal for securing beams, constructing outdoor structures, or any application exposed to saltwater, chemicals, or moisture where long-lasting durability is essential.

Key Benefits of Our Stainless Steel 316 Hex Lag Screws
