SANTIE 5/16 in. x 1-3/4 in. Zinc-Alloy Long Lag Shields Anchor - with Lag Bolts (2-Pack)

SANTIE lag bolt expansion shield anchors effortlessly fasten lag bolts into wood, concrete, and masonry. This 5/16" long lag bolt anchor for concrete creates a secure anchoring point. Installation involves threading the lag bolt, which causes the lag shield to expand and become locked into the material. It is made of Zinc Alloy for enhanced corrosion protection. For proper installation, pre-drilling a hole is recommended.

• Purpose & Suitable Materials：The Lag Shield is a screw-style expansion anchor designed for use with lag bolts in concrete, brick, block, or stone masonry. The short version is ideal for dense materials (e.g., hard concrete), while the long version provides better grip in soft or weak masonry.
• Corrosion Resistance & Durability：Made from zinc-plated steel or zinc alloy, it offers excellent rust and corrosion resistance, making it suitable for outdoor applications like play sets, frameworks, and plumbing systems.
• Strong Grip & Installation Requirements：Features heavy external corrugations for maximum expansion and holding power. Requires pre-drilling a pilot hole—threading the lag bolt expands the shield, locking it securely in place.
• Common Applications：Ideal for anchoring shelves, window frames, and masonry projects. Not recommended for overhead or life-safety-critical loads.
• Selection & Installation Tips：Short shields reduce drilling time in hard materials.Long shields improve strength in soft materials.Ensure the lag bolt length accounts for embedment depth, material thickness, and washer space.
