High Strength Friction Grip Bolts
High Strength Friction Grip (HSFG) Bolts are specialized high-tensile fasteners used in structural steel connections where load transfer occurs through friction between connected surfaces rather than shear on the bolt. These bolts are tightened to a specific torque to create a clamping force, ensuring slip-resistant joints. HSFG bolts are widely used in critical applications such as bridges, buildings, and heavy engineering structures.
Key Features of High Strength Friction Grip Bolts
- High Load Capacity: Designed to handle heavy structural loads efficiently.
- Friction-Based Connection: Ensures slip-resistant joints for enhanced safety.
- High Tensile Strength: Typically made from high-grade steel like 8.8 or 10.9.
- Reliable Performance: Maintains joint integrity under dynamic and vibration conditions.
- Corrosion Resistance: Available in galvanized or coated finishes for durability.
- Precision Tightening: Requires controlled torque for accurate installation.
