Our BoltHold asphalt anchors find use in hundreds of applications. The Library contains about 60 documents that are yours to read and download, as long as this is done in compliance with our Copyright Statement. All anchors are supplied with a bolt and a washer.
Below are popular examples of uses of our anchors. The Blog may also refer to some case histories.
-
Tent Anchoring- Use SP18 anchors to secure pole plates directly to the asphalt.
- Use SP12 if holes in base are below ½" diameter
- Use SP58 anchors with eye bolts to attach the tent guy wires to the ground.
- Use SP18 if tension in guy wires can be kept below 500 lb.
- The installation does not damage the asphalt.
- See Application Note AN60 for background information about the use of anchors for tents and canopies.
- See the Installation Guide for best installation practices.
- UNIQUE BENEFITS: Tent can be removed and anchors stay embedded in the asphalt for reuse.

Posts & Fences- You can install any post that has a mounting plate to asphalt
- Use our Fence Post calculator to choose suitable anchors
- The type of fence (solid wall, slats, chain link) has a major bearing on the wind force that needs to be resisted
- Use an oversized mounting plate to reduce the size/quantity of anchors required
- Consider placing a larger plate over the one the comes with the post
- Here is a link to an Application Note with more details about fence anchoring
- For posts that protect equipment against vehicle bumping, see Bollards application below

Bollards Bollards are heavy duty posts, used to prevent vehicular access or to protect structures from being accidentally hit. Bolt-mounted bollards can be installed directly to asphalt using our BoltHold anchors.Recommended anchors

Bike Racks One of the most common applications for our asphalt anchors is for mounting bike racks to asphalt. The suggested anchor is SP10-38.Recommended anchors

Road DelineatorsDelineators are vertical markers that guide vehicular traffic by creating a visible lane. A typical application is to separate traffic from crossing over from one lane to another, or to separate vehicles from pedestrians.Delineators are subject to heavy physical abuse from meandering vehicles. Most modern delineators are made from flexible high-visibility plastic, so that they yield but bounce back up if attacked. The forces on the base of the delineators are quite high, and most often epoxy glues are not strong enough to keep the delineators firmly attached for any length of time.

Signage Parking signs, traffic sign and any surface-mounted signs can be secured to asphalt using our BoltHold anchors.- Use our Sign Calculator to find the least-cost type and number of anchors that will meet the wind force requirements
- Note that sometimes using 2 of the stronger anchors is less expensive than using 4 of the smaller ones
- If using only two anchors, these must be installed diagonally from each other
- If there are only 3 holes in the base plate, use 3 of the anchor size where 2 would do. The reason is that with 3 hole bases, the holes are 120 degrees apart and you can not install them diagonally.

Speed Bumps- Plastic or rubber speed bumps and speed humps are used for traffic calming in private streets, parking lots and access roads.
- Speed humps are shallower and wider (in the direction of travel) than speed bumps.
- The SP18 is the recommended anchor for this application.
- For tough applications where continuous trucking traffic pounds the bumps, use our SP58 anchors.

Shopping Cart CorralsShopping cart corrals are mostly installed in parking lots. After at least one person was gravely injured during a windstorm that hurled a shopping corral, some major grocery chains started tying the corrals down using our BoltHold anchors.We recommend using the SP10 for areas with moderate (50mph) wind gusts or SP12 for areas where winds up to 70 mph are expected. Over 70 mph consider using the SP18 anchors.Always consult a professional engineer.Recommended anchors

Outdoor Furniture Outdoor furniture, such as benches, tables, multi-seated benches, and charging stations, can all be installed directly to asphalt. This is a significant cost and time saving over the replacement of asphalt with poured concrete, then installing expansion anchors in the cured concrete, and finally installing the furniture. The furniture can be readily removed or replaced by simply unbolting it from the anchors.Our anchors are used in hundreds of furniture installations in the public sector and in private facilities and parks.

Carports Carport anchoring is a popular application for our anchors. We have developed a special calculator that will guide you as to the type and number of anchors required for each post of the carport. The information below is a general guide. We recommend that you consult the calculator to find the lowest cost solution that meets the wind resistance requirements in your area.- For protected areas with winds below 50 mph, use 4 SP12 for each post
- For windy areas, use 4 SP18 for each post
- For lean-to carports that use the house as support on one side, use 4 SP10 on each post
For more elaborate carports, contact us for a free consultation.Recommended anchors

Storage Racks BoltHold asphalt anchors have been used to secure industrial storage racks against earthquakes and against accidental bumping by forklifts. As a rule, lighter shelving needs heavier anchors, because the weight of the shelving provide by itself resistance against accidental bumping. For earthquake protection the heavier anchors will likely perform better. Please consult a professional engineer when attempting to meet local safety codes.- Shelving must be stable with and without the merchandize on it.
- Shelf vertical posts must have heavy duty mounting plates on the bottom.
- The plates distribute the weight over a larger area of the asphalt to prevent sinking.
- Anchors must be installed under the mounting plates.
- Use SP18 or SP58. The SP10 or SP12 bolts do not have adequate shear capacity.

Ice Hockey Rink Recreational Ice Hockey rinks are often assembled over asphalt parking areas. The wall surrounding the rink is typically 4 feet high and is called the Boards. The boards need to resist player crashing into them. Our anchors have been used successfully to secure the brackets supporting the Boards. And once the season is over, the installation can be disassembled. The anchors stay in the asphalt, flush with the surface, and can be reused next season. To protect the thread of the anchors when not in use, use our ThreadGuard plastic snaps.
