High-Strength Anchor Rods (ASTM F1554 Grade 105)

Anchor fasteners are critical components used to secure structural steel columns, large machinery, and equipment foundations to concrete bases. The ASTM F1554 standard specifically covers anchor bolts and rods, and Grade 105 is the high-strength option, often supplied as L-shaped, J-shaped, or straight threaded rods. Due to their high yield strength, these rods are commonly paired with ASTM A194 Grade 2H Heavy Hex Nuts to achieve the required high preload without the nut stripping. These assemblies are used in heavy construction, bridge building, and power plant installations where seismic or high wind loads require maximum anchoring capacity. Zeron Fasteners manufactures F1554 Grade 105 rods from alloy steel, ensuring the material is quenched and tempered to meet the specified mechanical properties.
