Special Features

  • Dimensions: Internal thread 1/4x1-1/4x1/2. Internal thread length 1/4 inch, external diameter 1/2 inch, drilled with a 1/2-inch electric drill.
  • Application: For use with mechanical screws or bolts in soft masonry. It can also be used on harder materials, including stone, brick, concrete, or blocks.
  • Tap the expansion screw into the hole until flush, then screw in the screw. The expansion screw will distribute the tension shield to both sides, making it easier to screw in the screw.
  • The expansion screw guard is made of high-quality zinc alloy, durable and resistant to breakage or deformation, suitable for long-term use.
  • Style: Two-piece tubular guard, hollow wedge-shaped cone, and wedge-shaped nut. Tightening the screw causes expansion at both ends.
