BoltHold SP58 is a heavy duty asphalt anchor rated at 5,000 lbs. pull (at 3″ asphalt thickness). The 10″ long anchor Zinc plated anchor is designed to mount speed bumps and kerbs directly to asphalt surfaces.
The anchor incorporates a 5/8″-11 UNC (coarse) female thread. The thread of the bolt inside the anchor should not exceed 4″.
