Anchor Bolts – ASTM F1554 Grade 55
High-Strength Fasteners for Industrial Applications
Our ASTM F1554 Grade 55 Anchor Bolts are engineered for structural anchoring applications requiring superior strength, ductility, and durability. Manufactured to meet ASTM F1554 standards, these bolts are widely used for foundation anchoring of structural steel, columns, poles, and heavy equipment in commercial, industrial, and infrastructure projects.
Standard Compliance: Manufactured to ASTM F1554 Grade 55 requirements for guaranteed quality and performance.
High Yield Strength: Minimum yield strength of 55 ksi (380 MPa) ensures reliability in critical applications.
Ductile Material: Offers a balance of strength and flexibility to resist cracking under heavy loads.
Variety of Configurations: Available in straight, L-shaped, J-shaped, and forged head designs.
Thread Options: Supplied in UNC (Unified Coarse) or UNF (Unified Fine) threads, with full or partial threading available.
Protective Finishes: Options include plain, hot-dip galvanized, or zinc-plated finishes for enhanced corrosion resistance.

Q: What is the difference between ASTM F1554 Grade 36, 55, and 105?
A: Grade 36 has lower strength, Grade 55 offers medium strength with good ductility, and Grade 105 provides high strength but less ductility.
Q: Are Grade 55 anchor bolts weldable?
A: Yes, ASTM F1554 Grade 55 is weldable when ordered with supplemental requirements specifying weldability.
Q: What is the typical lead time for custom anchor bolts?
A: Standard sizes are usually in stock; custom lengths and configurations can be manufactured quickly based on project needs.
Q: Can these bolts be used in outdoor environments?
A: Yes, hot-dip galvanized or zinc-plated finishes provide excellent corrosion resistance for outdoor applications.
