Heavy-Duty M6-M20 Strike Anchors for Rapid Concrete Installation

Our Strike Anchors are the go-to solution for contractors who prioritize speed and reliability. Designed for use in solid concrete, these hammer drive anchors work by driving a center pin into the anchor body, forcing the bottom to expand against the hole walls. This impact-expansion mechanism ensures a permanent hold without the complex torque requirements of wedge anchors.

Available in Zinc Plated Carbon Steel for indoor use and Stainless Steel for maximum corrosion resistance in outdoor construction projects.

Why Use Strike Anchors?

  • No Torque Required: Saves significant labor time; just drill and hammer.
  • Visual Confirmation: Once the pin is driven flush with the top of the bolt, the anchor is correctly set.
  • Versatile Sizing: Full range from M6 to M20 to handle various load capacities.
  • Pre-assembled: Comes with nut and washer already attached for immediate use.

How to Install Strike Anchors Correct-way

  1. Drill: Use a hammer drill to create a hole the same diameter as the anchor.
  2. Clean: Clear all dust and debris from the hole for maximum grip.
  3. Insert: Place the strike anchor through the fixture and into the hole until the nut is snug against the fixture.
  4. Strike: Using a hammer, strike the drive pin until it is flush with the top of the threaded bolt. The anchor is now fully expanded.

Common Industrial ApplicationsThese Concrete Strike Bolts are ideal for projects requiring multiple fast installations:

  • Perimeter Fencing: Securing fence posts and railings to concrete slabs.
