Zeron Fastners
SS 347 Anchor Fasteners (Chemical / Mechanical Anchors)
SS 347 Anchor Fasteners are specialized fasteners designed for securing heavy loads and structural elements to concrete, masonry, or stone foundations. Unlike standard anchors, this high-grade material is an austenitic stainless steel stabilized with Niobium, making it exceptionally resistant to intergranular corrosion when exposed to high-heat zones (e.g., adjacent to welding or high-temperature ducts). Supplied by Zeron Fasteners, these anchors provide the dual benefit of high tensile strength and superior corrosion resistance, ensuring the integrity and safety of structures in harsh industrial environments such as power plants, chemical refineries, and coastal infrastructure. We offer variations including wedge anchors, sleeve anchors, and chemical anchor studs.
