Stainless Steel Concrete Wedge Anchors
Weight Range ： 0.5g–500kg
Dimensional tolerance ： ±0.1mm
Stainless steel concrete wedge anchors are high-strength mechanical anchors designed specifically for concrete. It is made of 304 or 316 stainless steel, with a chromium content usually exceeding 16%, which provides excellent anti-corrosion protection and can have a service life of more than five times that of ordinary carbon steel anchors in harsh environments. It is locked by expansion of the wedge-shaped structure at the tail. For example, an M12 anchor bolt can provide a pull-out force of more than 15 kN in C30 concrete. The installation process is also easy to control, and the standard installation torque of the M10 specification is about 40 to 50 Nm.
The design of this anchor bolt strictly follows safety regulations, and its minimum burial depth is generally 6 to 10 times the diameter of the bolt to effectively disperse stress and prevent concrete cracking. After the installation is completed, it can be loaded immediately without waiting, and can reach more than 80% of the rated bearing capacity, thus significantly improving construction efficiency. In addition, its all-metal structure has excellent high-temperature resistance and can maintain structural integrity in an environment lasting approximately 870 degrees Celsius, providing a reliable guarantee for fire safety in key parts.

Advantages
-
Strong earthquake resistance
High load-bearing capacity and shear resistance are provided by the wedge-shaped expansion mechanism, which creates a robust mechanical lock at the hole's bottom. Safe and dependable, suitable for dynamic loads and earthquake-resistant structures, and difficult to loosen under impact or vibration.
-
Small spacing requirement
Because it expands at the bottom of the hole, there is less space needed between the anchor bolt and the concrete substrate's edge, allowing for more creative fastening design in confined areas.
-
Later disassembly
After installation, the anchor can usually still be taken out of the hole by unscrewing the nut. This offers a benefit that many chemical anchors lack: ease of use for equipment modifications, repairs, or temporary structures.
Why choose us
Low risk of damage to concrete substrate
Its expansion stress can be distributed more evenly to the depth of the hole bottom because its expansion force is concentrated on the wedge-shaped portion at the end of the anchor bolt and the burial depth is typically required to be six to ten times the diameter of the anchor bolt.
This successfully lowers the possibility of splitting damage to the concrete surface during installation, particularly in thinner elements or close to edges.
Extremely high mechanical bearing capacity
This kind of anchor can generate incredibly high locking force at the bottom of the concrete hole thanks to its special wedge-shaped expansion principle.
An M12 304 stainless steel wedge anchor in C30 concrete, for instance, has a design tensile strength that can easily surpass 15kN, offering strong protection for vital structural connections.
Easy installation and controllable quality
Drilling, cleaning, inserting, and tightening are the only four standard steps needed to install it. Torque directly affects the final fastening quality.
For instance, an M10 anchor bolt's installation torque is typically between 40 and 50 N·m. This quantitative index lowers human error and facilitates the inspection and control of construction quality.
certifications that meet international standards
The fasteners offered by JOYEAR are frequently utilized in materials like grade 8.8 and higher alloy steel, 304/316 stainless steel, and others. Their mechanical characteristics meet GB, ASTM, DIN, and other international standards.
This makes it possible for its products to be readily utilized in high-quality engineering projects both domestically and internationally, as well as export equipment.
