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.
| Dimensi | Apa Artinya | Mengapa Itu Penting |
|---|---|---|
| Diameternya | Anchor body and thread size | Affects hole size, nut size, and load range |
| Panjang keseluruhan | Full anchor length from end to end | Must cover embedment plus fixture thickness |
| Panjang benang | Usable threaded section above the concrete | Must allow washer and nut engagement |
| Kedalaman penanaman | Depth of anchor inside concrete | Directly affects holding performance |
| Ketebalan perlengkapan | Thickness of the plate or bracket being fixed | Reduces available embedment if not calculated |
For general sourcing, buyers can review standard fastener options under pengencang standar.
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:
- Kekuatan beton
- Tension or shear load
- Jarak tepi
- Jarak jangkar
- Fixture hole size
- Required approval or project standard
For load-bearing installations, review pengencang berkekuatan tinggi 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.
Kesalahan Seleksi Umum
Hindari masalah ini:
- 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.
- Memilih pelapis tanpa memeriksa kecocokan benang.
For outdoor or humid environments, compare coating options under berbagai pengencang berlapis.
RFQ Checklist for Wedge Anchors
Sebelum meminta penawaran, berikan:
- Anchor diameter and length
- Panjang benang
- Ketebalan perlengkapan
- Kedalaman penyematan yang diperlukan
- Concrete strength and condition
- Arah beban: tegangan, geser, atau gabungan
- Permukaan akhir atau pelapisan
- Persyaratan mur dan mesin cuci
- Laporan pengujian atau sertifikat yang diperlukan
For unusual dimensions or project-specific anchor designs, use pengencang non-standar khusus dan memberikan gambar.
Saran Terakhir
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.
