The Bolthold SP58-58 asphalt anchor is a heavy-duty anchoring solution designed specifically for high-demand asphalt applications. This 10" asphalt anchor bolt is ideal for securing tents, speed bumps, curbs, and similar fixtures directly into asphalt surfaces. Each anchor is pre-installed with a bolt and washer and installs flush with the surface for a clean, low-profile finish.
Load anchors to no more than 80% of rated pull strength when the structure is self-supporting. If the structure applies a static pull force on the anchors, limit loading to 20% of the rated pull strength.
Engineered for strength and removability, the SP58-58 anchor requires a 1.5" diameter hole drilled 10" deep and the use of compatible grout to achieve proper holding power. A large top header prevents pull-through during tightening while allowing mounted items to be removed cleanly without leaving surface protrusions.
Required Grout:
Listed below are the approximate amounts of grout required to install one six-pack of SP58-58 asphalt anchors.
