QA Heavy Duty Anchor Bolt

Grade of screw strength: Grade 8.8 for carbon steel, SS A2-70 and A4-70

Range of use: Steel structure, railing, cantilever bracket, cable tray, mechanical equipment, elevator, stair, door & window and curtain wall.

Advantages:

1. The anchor bolt will be anchored in two ways with high shock resistance and outstanding safety performance.

2. The action directions of the anchor bolt at two self undercut positions are adverse, which may offset the expansion strain and results in small edge distance for anchoring.

3. It is unnecessary to drill additional holes when replacing with new anchor parts. Rotate the screw of the anchor bolt to remove it and replace with new anchor parts. Then re-install and fasten the removed screw.
