Anchoring – Technical Guidance and Anchor Selection
Selecting the right anchor depends on more than the product itself. Load, base material, concrete condition, edge distance, spacing, embedment depth and installation method can all affect the performance of an anchoring system.
Fabory's anchoring guidance helps engineers, installers and purchasing professionals understand the factors that influence anchor selection and installation, from light-duty fixings through to structural anchoring in concrete.
Anchors as the basis for a reliable connection
From fixing a balustrade to concrete to anchoring a steel column to a foundation, every application places different demands on the anchoring system.
The correct solution depends on factors including the applied tension and shear loads, the base material, cracked or non-cracked concrete, anchor spacing, edge distances and installation conditions. Correct drilling, hole cleaning, embedment and installation are equally important to achieving the specified performance.
For structural fastenings in concrete, anchor design may also need to be verified in accordance with EN 1992-4 using the performance data given in the relevant European Technical Assessment (ETA).
Calculate structural anchors with the Fabory Anchor Calculator
Anchor calculations can involve multiple interacting factors, including loads, concrete condition, anchor geometry, spacing and edge distances.
The Fabory Anchor Calculator helps you design post-installed anchors for structural use in concrete in accordance with EN 1992-4. Enter your project conditions to identify suitable anchoring solutions and understand why alternative anchors may not meet the design requirements.
- Design post-installed anchors to EN 1992-4
- Calculate for cracked and non-cracked concrete
- Assess fire and seismic design conditions
- Generate calculation reports for project documentation

Frequently asked questions about anchoring
Find answers to some of the most common questions about anchor selection, design and calculation.
What factors determine which anchor I should use?
Anchor selection depends on factors including the applied load, base material, concrete condition, edge distances, anchor spacing, embedment depth, environmental conditions and the requirements of the relevant product approval.
When is an anchor calculation required?
Structural and safety-critical fastenings should be designed in accordance with the applicable design standard and product approval. For post-installed fastenings in concrete in Europe, EN 1992-4 provides the design framework used alongside performance data from the relevant European Technical Assessment (ETA).
