Wedge anchors are post-installed expansion anchors used in solid concrete. They are common in base plates, pipe supports, equipment brackets, railings, steel frames, and light-to-medium structural fixing.
For buyers, the key point is simple: wedge anchor size is not only the diameter. Length and embedment depth are just as important. If any of these are wrong, the anchor may not seat properly, the nut may not engage fully, or the concrete connection may not reach the expected capacity.
Key Wedge Anchor Dimensions
A wedge anchor is usually defined by diameter and overall length. However, project buyers should also confirm thread length, fixture thickness, required embedment, and installation clearance.
| Dimension | Was es bedeutet | Warum es wichtig ist |
|---|---|---|
| Durchmesser | Anchor body and thread size | Affects hole size, nut size, and load range |
| Gesamtlänge | Full anchor length from end to end | Must cover embedment plus fixture thickness |
| Gewindelänge | Usable threaded section above the concrete | Must allow washer and nut engagement |
| Einbettungstiefe | Depth of anchor inside concrete | Directly affects holding performance |
| Dicke der Vorrichtung | Thickness of the plate or bracket being fixed | Reduces available embedment if not calculated |
For general sourcing, buyers can review standard fastener options under Standardbefestigungen.
Diameter Selection
Match the Load and Hole Requirement
Larger diameters usually provide higher potential load capacity, but only when concrete strength, edge distance, spacing, and embedment are suitable.
Do not select diameter only by the hole in the base plate. Confirm:
- Betonfestigkeit
- Tension or shear load
- Randabstand
- Ankerabstand
- Fixture hole size
- Required approval or project standard
For load-bearing installations, review hochfeste Verbindungselemente and confirm engineering requirements before ordering.
Length and Embedment Depth
Overall length must be long enough to pass through the fixture and still reach the required embedment in concrete.
A practical calculation is:
Anchor length = fixture thickness + required embedment + washer/nut allowance + thread projection
If the anchor is too short, embedment may be insufficient. If it is too long, installation may be difficult or unnecessary cost may increase.
Häufige Auswahlfehler
Vermeiden Sie diese Probleme:
- Ordering by diameter only.
- Ignoring fixture thickness.
- Confusing overall length with embedment depth.
- Using wedge anchors in weak or unsuitable concrete.
- Placing anchors too close to concrete edges.
- Forgetting washer and nut requirements.
- Choosing coating without checking thread fit.
For outdoor or humid environments, compare coating options under verschiedene beschichtete Verbindungselemente.
RFQ Checklist for Wedge Anchors
Bevor Sie ein Angebot anfordern, stellen Sie Folgendes bereit:
- Anchor diameter and length
- Gewindelänge
- Dicke der Vorrichtung
- Erforderliche Einbettungstiefe
- Concrete strength and condition
- Belastungsrichtung: Zug, Scherung oder kombiniert
- Oberflächenveredelung oder Beschichtung
- Anforderungen an Muttern und Unterlegscheiben
- Erforderliche Prüfberichte oder Zertifikate
For unusual dimensions or project-specific anchor designs, use kundenspezifische, nicht standardmäßige Verbindungselemente und Zeichnungen zur Verfügung stellen.
Abschließender Rat
Wedge anchor size should be selected by installation conditions, not by diameter alone. Confirm diameter, length, embedment depth, fixture thickness, concrete condition, and coating before production.
A complete RFQ helps avoid wrong anchors, weak installation, and costly jobsite rework.
