5/8" x 3 1/2" Long Lag Screw Expansion Shield, Zinc

• 

Our 5/8" x 3 1/2" Lag Screw Expansion Shields are used with lag bolts to secure into concrete or masonry. Often, these are ideal to help support connection in hollow or brittle base materials. The shield distributes the load, reducing the risk of cracking. Further, the lag screw shields help support the threads also reducing the risk of pulling out for heavy duty mounting.
