Lag Screw Shield

Lag screw shields are durable expansion anchors designed for securing lag screws into masonry materials such as concrete, brick, block, and mortar. Made from high‑strength, corrosion‑resistant materials (typically zinc alloy or similar die‑cast metals), these shields provide a secure, vibration‑resistant hold where direct screw insertion isn’t reliable.
The shield expands outward when a lag screw is driven in, gripping the surrounding masonry firmly. Their longer body and segmented expansion design allow for deep embedment and strong load capacity, making lag screw shields an excellent choice for heavier installations where simple plastic anchors would fail.
These anchors are commonly used in both residential and commercial settings for medium‑ to heavy‑duty anchoring tasks. Not finding what you're looking for? Reach us by calling 866-463-2910 or by filling out the contact us form, and one of our knowledgeable sales staff will contact you shortly!

Lag screw shields are typically used for fastening:

Outdoor fixtures
Handrails & guardrails
Signage & mounting plates
Machinery and equipment supports
Exterior hardware
Pipe straps, conduit clips & bracing
Utility boards, furring strips & lumber
Available in short and long styles to match the depth and strength required, lag screw shields offer reliable expansion performance even in softer or crumbly masonry substrates. Installation is simple—drill the appropriate hole, insert the shield flush with the surface, and drive the lag screw to expand and secure the anchor.
These shields provide consistent torque resistance, strong pull‑out values, and a dependable long‑term hold for structurally demanding applications.
