DIN529 Anchor Bolts TypeA
DIN 529 Type A anchor bolts are bent-end foundation bolts designed for secure anchoring in concrete, masonry and structural applications. They feature a curved hook-shaped anchoring end and a threaded shank, allowing the embedded end to provide mechanical anchorage while the exposed threaded section is used with a nut to secure equipment, structures and other components. The standard size range covers metric thread diameters from M8 to M72, including M72 × 6, with different thread lengths and overall lengths available according to the bolt diameter and application requirements.
DIN 529 Type A anchor bolts can be supplied in carbon steel, alloy steel and stainless steel, with commonly specified carbon steel grades including 4.6, 5.6 and 8.8, as well as high-strength materials such as EN 42Crmo4(1.7225) for suitable applications. Standard and customized lengths can be supplied, while surface finishes such as plain, galvanized, electroplated, sherardized and other coatings are available depending on the material and application.
Specification:
DIN 529 Type A anchor bolts are manufactured according to the dimensional and technical requirements of DIN 529 and feature a curved hook-shaped anchoring end with a threaded shank. The standard covers metric thread sizes from M8 to M72, with M72 × 6 specified for the largest size. Available dimensions include different nominal diameters, thread pitches, thread lengths, overall lengths, hook dimensions and shank diameters according to the selected size. The bolts can be supplied in different carbon steel, alloy steel and stainless steel materials, with property classes and material grades selected according to the required application and customer specifications.
For different installation environments, DIN 529 Type A anchor bolts can be supplied with plain or protective surface finishes, including zinc plating, hot-dip galvanizing and other suitable coatings. We can also provide different thread lengths, overall lengths and material options for specific foundation and anchoring requirements.

Application of DIN529 Anchor Bolts TypeA:
Foundation & Concrete Structures
DIN 529 Type A anchor bolts are commonly used in foundations and concrete structures where equipment, steelwork or other components need to be securely anchored to a concrete base. The curved hook end is embedded into the concrete to provide mechanical anchorage, while the threaded section remains accessible for fastening with nuts.
Structural Steel & Construction
For structural steel and construction projects, DIN 529 Type A anchor bolts can be used to secure steel columns, base plates, frames and other structural components to concrete foundations. Different diameters and lengths allow the bolts to be selected according to the load requirements and installation conditions of the project.
Machinery & Equipment Installation
DIN 529 Type A anchor bolts are also suitable for installing machinery, industrial equipment and heavy components onto concrete foundations. Their embedded hook-shaped end provides a stable anchoring point, while the threaded upper section allows equipment and mounting plates to be securely fixed and adjusted with nuts.
Stainless Steel Anchoring Applications
Stainless steel DIN 529 Type A anchor bolts are suitable for anchoring applications where corrosion resistance is an important requirement. They can be used in outdoor structures, coastal and marine environments, food processing facilities, water treatment equipment and other installations exposed to moisture, humidity or corrosive conditions. Stainless steel grades such as SS304 and SS316 can be selected according to the environmental conditions and required corrosion resistance, providing a durable anchoring solution for concrete foundations and structural components.
