Concrete Screw (Tapcon) vs. Wedge Anchor
Two very different ways to fasten to concrete: a removable screw that cuts threads, or a permanent wedge that locks in place.
| Feature | Concrete Screw (Tapcon) | Wedge Anchor |
|---|---|---|
| Strength | Medium | Very high |
| Removable | Yes (unscrew) | No (permanent) |
| Base materials | Concrete, brick, block | Concrete only |
| Installation | Pilot hole + drive | Drill + hammer set + torque nut |
| Typical cost per fastener | Under $1 each in boxes | $1–3+ each |
| Tools needed | Hammer drill + nut driver | Hammer drill + hammer + wrench |
| Under vibration | Can loosen over time | Holds under vibration and shock |
| Best for | Fixtures, conduit, light loads | Structural loads, machinery |
Verdict
Use Tapcons for removable, medium-duty fastening to concrete and brick. Use wedge anchors when the load is structural and permanence is fine.

FAQ
Can Tapcon screws be removed and reused?
They unscrew cleanly and the hole can be reused once or twice, but each cycle cuts the threads looser. For a permanent re-fastening in the same hole, step up a diameter or switch to an expansion anchor.
Do wedge anchors work in brick or block?
Not reliably — the expansion force can crack brick and blow out block cells. Wedge anchors belong in solid concrete; use sleeve anchors or concrete screws for brick and block.
