Zeron Fastners
SS 310 Anchor Fasteners
SS 310 Anchor Fasteners are specialized metal components used to secure various types of refractory linings (such as bricks, monolithic casts, or ceramic fiber blankets) to the shell or structure of high-temperature equipment. These fasteners are critical for maintaining the structural integrity of the insulation under extreme thermal conditions and thermal cycling. Typical forms include V-anchors, Y-anchors, C-clips, and stud anchors. The material, high-chromium, high-nickel austenitic stainless steel (UNS S31000), provides exceptional resistance to oxidation and scaling, remaining structurally sound in continuous service up to 2000°F (1093°C). This superior performance prevents anchor failure and costly insulation collapse common in high-heat environments like industrial furnaces, petrochemical heaters, and cement kilns. Zeron Fasteners manufactures and supplies a variety of robust SS 310 Anchor Fasteners, designed for easy installation and long service life in the most demanding thermal applications.
