Applications
- Used in structural projects like bridges and high-rises.
- Essential for industrial machinery assembly.
- Ensures corrosion-resistant connections in outdoor environments.
- Provides strong, secure connections in civil engineering.
Process
- Position the Washer: Place the HSFG washer between the bolt and the structure for high-strength applications.
- Insert the Bolt: Place the bolt through the washer and into the pre-drilled holes.
- Tighten: Tighten the nut to the required torque, ensuring the washer compresses to create a secure connection.
- Check Tightness: Ensure proper tightening and recheck torque after installation to ensure load distribution.
Precision-Engineered HSFG Washers for Structural Applications
Our HSFG washers are manufactured to support high tensile bolts in structural steel joints where slip resistance and load stability are critical. Each washer is engineered for accurate thickness, uniform hardness, and dependable field performance.
What Are HSFG Washers?
HSFG (High Strength Friction Grip) washers are used along with HSFG bolts and nuts to create friction-based structural connections. These washers help maintain clamping force and prevent joint slippage under dynamic loads, making them ideal for bridges, steel structures, and heavy engineering works.
Our Manufacturing Capability
Fasteners India uses precision stamping and machining systems combined with heat treatment and surface finishing processes to manufacture HSFG washers that meet industrial standards. Each batch undergoes inspection to ensure performance consistency and compliance.
