3/8" Hollow Drop-In Anchor, Zinc

• 

Simpson Strong-tie zinc plated hollow drop-in anchors are ideal for a strong, reliable connection in hollow base material as well as solid base material. To install, simply pre-drill the hole and set the anchor flush with the base material. Once installed, the anchor is ready to accept any length bolt or threaded rod of the same diameter, 3/8", offering flexibility for a wide range of applications. The hollow drop-in anchors are a great choice for secure fastening when a flush finish is required, giving your project a clean look.
