4 Best Concrete Anchor Kits, Ranked: Tapcon, Simpson and Hillman
Most homeowners buy the wrong anchor kit — either cheap unrated anchors that pull out under load, or overkill structural anchors for light shelving work. Here are the best kits for every application in 2026.
Quick answer: Start with a Tapcon screw kit — it covers about 80% of homeowner needs (electrical boxes, shelving, furring strips) and works in concrete, brick, and block. Add a wedge anchor kit for heavy structural work like deck ledgers or machinery (solid concrete only). For mixed substrates in one package, a Simpson Titen HD screw anchor delivers more holding power in concrete and masonry than Tapcon, or a Hillman sleeve anchor covers both concrete and masonry (brick/block) in one anchor type.

1. Tapcon Concrete Screw Kit — Best All-Round Starter Kit
The Tapcon kit is the right first purchase for any homeowner doing concrete work. Tapcon screws install with a standard hammer drill, are removable, work in concrete, brick, and block, and handle the vast majority of residential applications — electrical boxes, shelving brackets, furring strips, door frames, and light fixtures.
The standard kit includes both 3/16" and 1/4" screws with the correct carbide masonry bits. This is the one kit that covers 80% of homeowner anchor needs.
Who should buy it: Any homeowner starting out with concrete anchoring. Buy this first before investing in heavier anchor systems.
2. Simpson Strong-Tie STB2 Wedge Anchor — Best for Heavy Structural Work
When you need real load capacity — deck ledger boards, machinery anchoring, structural brackets — wedge anchors are the answer. The Simpson STB2 is ICC-ES listed with published load values and is accepted by building inspectors across North America — and unlike most wedge anchors, it is rated for cracked concrete and seismic categories A through F. A 1/2" wedge anchor in 3,000 psi concrete holds over 5,000 lbs in tension.
Important: Wedge anchors require solid concrete only. They cannot be used in hollow block, brick, or cracked concrete. For mixed substrates use the Tapcon or sleeve anchor kits instead.
Who should buy it: Anyone anchoring decks, machinery, heavy shelving, or structural connections to solid poured concrete.
3. Simpson Strong-Tie Titen HD Screw Anchor — Best Heavy-Duty Screw Anchor
The Titen HD is Simpson Strong-Tie’s heavy-duty screw anchor — the step up from Tapcon when you need more holding power in solid concrete or masonry. It’s a self-undercutting, non-expansion anchor code-listed under ICC-ES ESR-2713 for cracked and uncracked concrete, and ESR-1056 for masonry, so it holds rated capacity on a real job site pour, not just a lab-perfect slab. Install with a standard hammer drill using a bit matched to the anchor diameter — no separate sleeve, no special tools.
Who should buy it: Anyone who needs more holding power than Tapcon offers but doesn’t need a permanent wedge anchor — heavier brackets, equipment mounts, or masonry applications where wedge anchors aren’t rated.
4. Hillman Sleeve Anchor — Best for Concrete and Masonry
This Hillman sleeve anchor — unlike the wedge anchor above — works in concrete and masonry (brick, block), not concrete alone. A split expansion sleeve wraps a threaded stud body, giving full 360-degree contact with the hole for reliable holding power across substrate types. Preassembled for faster installation, and can be installed straight through the fixture into the wall — no separate pilot marking step.
Who should buy it: Anyone anchoring into mixed or unknown substrates (concrete, brick, or block) who wants one anchor type that works reliably across all three, without needing a different product per material.
How Each Anchor Type Actually Works
Every anchor in this guide falls into one of three basic mechanisms. Understanding how each one physically holds explains why substrate matters as much as brand.
Screw Anchors (Tapcon, Titen HD)
Screw anchors cut their own threads directly into the pilot hole as they're driven in — no separate expansion mechanism. Holding power comes from the threads gripping the surrounding concrete or masonry. This is why oversizing the pilot hole even slightly can cut capacity dramatically: the threads never fully engage.
Wedge Anchors
A wedge anchor has an expansion clip at the tip. As the nut is tightened at the surface, it draws a tapered pin up through the clip, forcing it to flare outward against the sides of the hole. This is a permanent mechanical expansion — which is why wedge anchors require solid, uncracked concrete with enough surrounding material to expand into.
Sleeve Anchors (Hillman)
A sleeve anchor wraps a split metal sleeve around a threaded stud body. Tightening the nut compresses the sleeve outward against the full length of the hole, rather than just the tip — giving more even contact in brick and block, not just solid poured concrete.
How to Choose the Right Anchor Kit
Three questions determine the right anchor for your project.
1. What's the substrate?
| Product | Solid Concrete | Brick | Solid Block (CMU) | Hollow Block |
|---|---|---|---|---|
| Tapcon Screw | Yes | Yes | Yes | Face shell only, not through hollow core |
| Wedge anchor | Yes | No | No | No |
| Simpson Titen HD (screw) | Yes | Yes | Yes | No |
| Hillman (sleeve) | Yes | Yes | Yes | No |
Hollow block face shells only accept screws, not expansion anchors. For true hollow-wall applications (drywall, hollow block interior cavity), use toggle bolts or specialty hollow-wall anchors instead — none of the products above are rated for that use case.

2. How much load per anchor?
Divide your total fixture weight by the number of anchor points to get load per anchor, then check it against the anchor's rated capacity (see the FAQ below for typical ranges by size). For a project-specific number rather than a general range, the Anchor Load Calculator factors in concrete strength, embedment depth, and edge distance.
3. Interior or exterior/wet?
Standard zinc-plated hardware corrodes within a few seasons outdoors or in damp environments. Check the specific product listing for a stainless steel (SS) or hot-dip galvanized (HDG) variant before buying if the installation is exterior or exposed to moisture.
Basic Installation Steps
Every anchor in this guide follows the same core sequence — the details differ by type.
- Drill the pilot hole to the anchor's specified diameter and depth. Never oversize — even a slightly larger hole reduces holding capacity for every anchor type on this page.
- Clear the hole completely. Dust left behind acts as a lubricant and can cut holding capacity by 30–50% even when everything else is done correctly.
- Insert the anchor — through the fixture first for wedge and sleeve anchors, or hand-start screws before driving them the rest of the way.
- Torque or drive to the manufacturer's specification. Undertightening leaves the anchor loose; overtightening can crack the substrate, especially in brick or block.
- For structural or load-bearing installations, verify your spec against the Anchor Specification Engine or a licensed engineer before finalizing.
Frequently Asked Questions
What concrete anchor kit should a homeowner buy?
Start with a Tapcon screw kit - it covers 80 percent of homeowner applications. Tapcon screws work in concrete, brick, and block, install with a standard hammer drill, and are removable. For heavy structural work like deck ledger boards add a wedge anchor kit. For mixed or unknown substrates, a Hillman sleeve anchor works reliably across concrete, brick, and block without switching anchor types.
What is the difference between Tapcon screws and wedge anchors?
Tapcon screws are concrete screws that thread directly into the base material. They are removable, work in concrete, brick, and block, and handle light to medium loads up to about 500 lbs. Wedge anchors are expansion anchors that wedge against the concrete as the nut is tightened. They are permanent, require solid poured concrete only, and handle heavy structural loads up to 9,000 lbs or more depending on size.
Can I use concrete anchors in hollow concrete block?
Standard wedge anchors and sleeve anchors cannot be used in hollow block - they require solid material for the expansion mechanism to work. For hollow concrete block use toggle bolts, hollow wall anchors, or specialty block anchors. Tapcon screws can be used in the solid face shells of hollow block but not through the hollow cores. Always identify your substrate before selecting an anchor.
How much weight can concrete anchors hold?
Load capacity varies significantly by anchor type and size. A 3/16 inch Tapcon screw holds approximately 100 to 300 lbs in tension in 3,000 psi concrete. A 1/2 inch wedge anchor holds 3,000 to 5,000 lbs in tension. A 5/8 inch wedge anchor holds 5,000 to 9,000 lbs. These values depend on concrete strength, embedment depth, and edge distance. Use the Anchor Specification Engine for project-specific calculations.
What drill bit do I need to install concrete anchors?
Each anchor type requires a specific bit size matched exactly to the anchor diameter. For Tapcon 3/16 inch use a 5/32 inch carbide bit. For Tapcon 1/4 inch use a 3/16 inch carbide bit. For wedge and sleeve anchors the hole diameter matches the anchor diameter exactly - a 1/2 inch anchor needs a 1/2 inch SDS carbide bit. Never use a larger bit - the anchor will not expand properly and will pull out under load.
Not sure which bit matches your anchor?
The Drill Bit Selector gives you the exact bit size and type for any anchor, material, or fastener — free, no signup.
Can I reuse a hole if I remove an anchor?
Generally no for wedge and sleeve anchors — removing them collapses or deforms the expansion mechanism, and the enlarged hole reduces holding capacity even with a new anchor. Drill a new hole nearby instead. Tapcon and Titen HD screw anchors can sometimes be reinstalled once in the same hole if the threads are still intact, but a fresh hole is safer for anything load-bearing.
Why is my anchor spinning instead of tightening?
This almost always means the hole is oversized, the anchor bottomed out before the expansion mechanism engaged, or (for screw anchors) the threads stripped the pilot hole. Remove it, inspect the hole, and redrill nearby with the correct bit size rather than continuing to force it.
How deep should I drill?
Deeper than the anchor's rated embedment depth — typically by at least 1/4" to 1/2" to account for dust in the bottom of the hole and to give screw anchors room to seat fully. Exact embedment depends on anchor diameter and length; use the Anchor Specification Engine for your specific anchor and load.
Can I drill into rebar by accident?
Hitting rebar with a masonry bit will stop the drill dead or cause the bit to skate — don't force through it. Move the hole location an inch or two in any direction. For structural anchors in reinforced concrete, a rebar scanner is worth the cost to avoid this entirely, especially near slab edges where rebar is common.
Do worn drill bits make the hole too large?
Yes — a dull carbide bit can drill an oversized, rough hole even at the correct nominal diameter, which reduces anchor holding capacity the same way manually oversizing would. Replace masonry bits once they stop cutting cleanly; they're a consumable, not a one-time purchase.
