7 Must‑Try Anchors for Asphalt – Top Picks Reviewed
We’ve tested countless options, and these seven anchors consistently deliver superior grip and durability for any asphalt application.
7. Bosch Speed Steel Screws for Asphalt & Concrete
These 30 stainless‑steel speed‑steel screws are the workhorse you need for every asphalt‑anchor job. Each screw is engineered as an expansion anchor that bites into concrete, asphalt, or packed soil, giving you a rock‑solid hold for speed‑bump plates, parking curbs, driveway railings, and even indoor projects such as wall brackets, picture frames, or cabinet fittings. The package includes a mix of bolt stoppers and plastic speed‑bump pads that resist deformation, so the bump stays firm under repeated vehicle loads. Thanks to their corrosion‑resistant finish, the fasteners stay reliable year‑round, whether you’re fixing a road‑grade curb or a drywall‑mounted shelf. Installation is straightforward: drill a pilot hole, insert the screw, and the built‑in expansion wedge secures the anchor instantly, eliminating the need for extra washers or nuts.
Pros
- Versatile application – works on concrete, asphalt, driveways, walls, cabinets, and more.
- Durable stainless‑steel construction – resists rust and heavy‑load fatigue.
- Easy, one‑step installation – expansion design locks in place without extra hardware.
Cons
- Requires a pre‑drilled hole of the correct diameter; improper sizing can reduce holding power.
- Plastic bump pads, while sturdy, may need occasional replacement in high‑traffic areas.
6. BoltHold SP10-38 Asphalt Anchor Kit
BoltHold’s SP10‑38 zinc‑plated asphalt anchors make mounting anything on asphalt as easy as a three‑step drill‑fill‑tighten process. Each 6‑inch anchor is forged from zinc‑plated steel, features a 3/8‑16 UNC female thread, and comes pre‑installed with a 1‑inch hex bolt and matching washer—six anchors per pack. The welded spiral design bonds securely with EPX2 or EXP3 anchoring grout (sold separately), creating a stress‑free, long‑lasting connection that reaches through the asphalt into the compacted gravel below. Rated for a 1,500 lb pull‑out and 1,000 lb of moderate shear, the anchors handle light‑to‑medium loads such as sheds, carports, bike racks, signage, and lighting fixtures. The top washer prevents the anchor from sinking below the surface, keeping the installation flush with the ground and eliminating tripping hazards. Installation time ranges from 15 minutes to an hour, depending on grout cure conditions, delivering a fast, cost‑effective alternative to pouring concrete footings.
Pros
- Rapid, no‑concrete installation – drill, fill with grout, and tighten in minutes.
- Strong pull‑out and shear capacity – 1,500 lb pull rating and 200 in‑lb torque for reliable performance.
- Flush‑mount design – washer keeps the anchor level with the surface, eliminating trip hazards.
Cons
- Requires separate grout – EPX2/EXP3 anchoring grout is sold separately, adding an extra purchase.
- Best for light‑to‑medium loads – not intended for heavy‑duty structural applications.
5. BoltHold SP12-38 Asphalt Anchors
BoltHold SP12‑38 zinc‑plated steel anchors are built for the toughest asphalt‑mounted projects. Each 12‑inch, 5/8‑inch anchor comes with a 1‑inch hex bolt and washer, letting you secure sheds, carports, bike racks, signage, lighting, parking barriers, and more without ever touching concrete. The industrial‑grade zinc coating resists corrosion, while the deep‑embed design locks the anchor into the asphalt’s sub‑base, eliminating the wobble and loosening that plague traditional wedge anchors. Installation is a breeze: drill the recommended hole, fill it with EPX2 or EPX3 grout (sold separately), tap the anchor in, and tighten the bolt. In under 15 minutes you have a 2,000 lb pull‑rated, 1,500 lb shear‑rated connection that stands up to wind, traffic, and everyday use.
Pros
- Heavy‑duty pull capacity – 2,000 lb pull rating and 1,500 lb shear rating provide a rock‑solid hold for medium‑load applications.
- Designed for asphalt – Deep‑embed geometry creates a stress‑free bond that won’t loosen like standard wedge anchors.

3. FOMMEN Rebar Stakes 16 Inch Metal Spikes (6 Pack)
The FOMMEN Rebar Stakes are built for demanding traffic‑control and landscaping jobs. Each 16‑inch, ½‑inch‑diameter steel spike is galvanized for rust‑proof durability, making it perfect for asphalt, concrete, tarmac, or any hard‑surface installation. The 1‑inch wide, chisel‑pointed top grips securely, so when you wrap a rope or cable around it, the material won’t slip. Their high‑strength construction lets you anchor speed bumps, wheel stops, garden plants, tent lines, survey markers, and even concrete‑forming timbers with confidence. The six‑pack gives you enough stakes for a small project or to keep a reliable stock on hand.
Pros

Buying Guide
When selecting anchors for asphalt, the most important considerations are the anchor’s holding power and its resistance to corrosion.
- Load capacity – Choose an anchor rated for at least the maximum static and dynamic loads you expect, because undersized anchors can pull out under traffic vibrations.
- Corrosion resistance – Asphalt environments expose metal to moisture and road salts; stainless‑steel or hot‑dip galvanized anchors will maintain strength longer.
- Installation method – Look for anchors that can be driven or screwed with standard impact drivers or concrete drills, reducing labor time and tool costs.
- Material compatibility – Ensure the anchor’s shank and sleeve match the asphalt thickness and any underlying base material, preventing cracking or settlement.
- Price‑to‑performance – Compare the cost per anchor against its load rating and warranty; a slightly higher price often yields longer service life and better value.
By weighing load capacity, corrosion protection, ease of installation, material fit, and overall value, you can choose anchors that stay secure for the life of your asphalt project.
Frequently Asked Questions
What type of anchor is most suitable for securing fixtures in asphalt surfaces?
Answer:
A concrete wedge anchor (also known as a sleeve anchor) is generally the best choice for asphalt. It expands against the surrounding material when the bolt is tightened, providing strong, vibration‑resistant holding power. Look for anchors rated for ≥ 3,000 psi compressive strength and a minimum embed depth of 1½ in to ensure reliable performance.
How should I prepare the asphalt before installing an anchor?
Answer:
1. Clean the area – remove loose debris, dust, and any oil or grease.
2. Drill a pilot hole using a carbide‑tipped masonry bit sized per the anchor manufacturer’s specifications (usually ½ in to ¾ in).
3. Clear the hole with compressed air or a vacuum to eliminate dust, which can reduce the anchor’s grip.
4. Moisten the hole lightly (if recommended) to prevent the bit from overheating and to improve the anchor’s expansion.
Can I use expansion bolts or lag screws directly in asphalt without a sleeve?
Answer:
While expansion bolts can work in some cases, they are less reliable in asphalt because the material can compress and crack under load. Lag screws are not recommended unless a metal sleeve or anchor plate is used, as they rely on thread friction alone, which asphalt cannot provide consistently. For lasting, safe installations—especially for heavy loads—always opt for a wedge or sleeve anchor system designed for masonry and asphalt.
Conclusion
Choosing the right anchor for asphalt applications hinges on balancing strength, durability, and ease of installation, ensuring the fastener can withstand both static loads and the harsh environmental conditions typical of pavement projects. Prioritizing corrosion‑resistant materials and secure engagement with the substrate reduces long‑term maintenance while protecting the integrity of the surface. Equally important is matching the anchor’s design to the specific load requirements and the type of asphalt product being used, which helps prevent premature failure and costly repairs. By evaluating these factors holistically, contractors can achieve reliable performance, extend the lifespan of their work, and ultimately deliver safer, more resilient infrastructure.
