Lag Screws Hex 18/8 Stainless Steel 3/8 X 14 are a premium fastener designed for heavy-duty timber connections that resist the elements.

Engineered with 18/8 stainless steel, these hex lag screws deliver superior corrosion resistance and strength for outdoor decks, pergolas, fences, and structural framing. The 3/8 inch diameter and 14 inch length provide robust holding power in dense wood while minimizing the risk of pull-out under load.

Why choose hex lag screws in stainless steel?

• Material: 18/8 stainless steel (304-grade) for corrosion resistance in damp and outdoor environments.
• Size: 3/8 in diameter x 14 in long for deep embedding and strong joints.
• Head: Hex head for easy driving with a hex bit or socket.
• Strength: Ideal for heavy timber connections, fence posts, and deck framing where high load capacity is required.
• Durability: Stainless construction resists rust, staining, and weathering over time.

Recommended applications

• Outdoor decks, pergolas, retaining walls, and garden structures
• Timber-to-timber connections where a secure, long-lasting joint is needed
• Projects exposed to moisture, splash zones, or coastal environments

Tips for best results: predrill pilot holes suited to your wood species to reduce splitting, and use a compatible hex driver to achieve full seating without stripping the hex head.
