Lock bolts are high-strength, tamper-resistant fasteners used in structural applications to securely join materials. They consist of two main components: a hardened steel pin with locking grooves and a collar that swages onto the grooves during installation.
Lock bolts are commonly installed using pneumatic or hydraulic tools that pull the pin while swaging the collar into place. Once installed, the excess pin breaks off at a predefined point, leaving a smooth, finished joint.
Key Features of Lock Bolts:
- High Strength: Designed for heavy-duty applications like construction, automotive, aerospace, and railway industries.
- Vibration Resistance: The swaged collar provides a tight fit, preventing loosening due to vibrations.
- Tamper-Proof: Once installed, lock bolts cannot be easily removed without specialized tools.
- Corrosion Resistant: Often made of stainless steel, aluminum, or coated steel for durability in harsh environments.
- Consistent Clamp Force: Ensures uniform and secure fastening compared to conventional nuts and bolts.
