Hex Bolt
Hex Bolts are standard fastening components characterized by their six-sided head, which allows for secure tightening with a wrench or socket. They are widely used in various industries including construction, automotive, and machinery due to their durability and strength. The hexagonal shape provides a greater surface area for applying torque, ensuring a tight and reliable connection.
These bolts are available in various materials and sizes to accommodate different load requirements and environmental conditions.
- Standard six-sided head for secure fastening
- Suitable for a wide range of applications
- Available in multiple materials and sizes
- Provides strong and reliable connections
- Easy to install with standard tools
