Wedge Anchor

Wedge Anchor Bolt is a high-strength anchoring component that is fixed using the mechanical wedge principle. It consists of a threaded rod, expansion sleeve, nut, and wedge block. When tightening the nut, the wedge block forces the sleeve to expand, forming a mechanical interlock with the concrete hole wall, in accordance with ASTM F1554 standard.

Features of Wedge Anchors


Wedge Anchor Bolt Title:

High Quality expansion wedge anchor bolt steel & stainless steel concrete anchor bolt


Core advantages

Instantaneous load bearing: Using patented mechanical locking technology, it can directly bear the design load without waiting for curing time after installation, especially suitable for emergency reinforcement scenarios.


Dynamic stability: The unique wedge-shaped expansion structure is designed with multi-directional stress dispersion, which can maintain over 90% of the initial preload force under continuous vibration, impact and other dynamic load conditions, meeting the high dynamic environmental requirements of bridges, rail transit, etc.


Anti corrosion upgrade: We offer two anti-corrosion solutions: hot-dip galvanizing and A2/A4 stainless steel, suitable for extreme corrosive environments such as coastal areas and chemical plants.


Aperture adaptation: The innovative elastic sleeve design enables a single product diameter to be compatible with a drilling tolerance of ± 1mm, effectively solving the problem of on-site drilling deviation and significantly improving construction efficiency.


Material specifications:

Carbon steel: ASTM grade 8.8, hot-dip galvanized;

Stainless steel: AISI 316, passivated treatment;

Standard diameter: M6-M24 or Customized

Manufacturing process:

Adopting multi station cold heading forming+fully automatic heat treatment line+optical sorting and detection;
