ANCHORING TO ASPHALT
BoltHold is a family of anchors specifically designed for asphalt. The anchors are flush-mounted to the asphalt and provide a clean internal thread for attaching bolts to the anchors. All anchors are supplied with bolts and washers.
Installation requires drilling a hole and filling it with our inexpensive grout (EPX2 or AGE2*), then pushing the anchor in until it is flush with the asphalt surface. The grout hardens in 15 minutes allowing immediate installation. Full strength may take an hour. Anchors are rated for asphalt 2" (50mm) or thicker.
Here is a link to an article in American Fastener Journal titled Asphalt Anchors 101. It provides an extensive introduction to the do's and don't when it comes to fixing anything to asphalt.
We offer a choice of 3 materials (Carbon steel with Zinc plating, Carbon steel with Dacromet coating, or 304 Stainless Steel) and 2 standards of internal threads (Imperial and Metric).
Our anchors will resist pullout forces exceeding 1,500 lb., with some rated at 2,500 lb in 2" asphalt. The resistance is much higher in thicker surfaces.

* The EPX2 is available only in the USA and Canada. In EU and other countries, we offer the AGE2 grout instead.
