Understand Big Head Screws
What are Big Head Screws?
Big head screws are a unique category of fasteners characterized by their larger head diameters. This design enhances their load-bearing capabilities and provides a wider bearing surface, making them ideal for applications where material integrity is paramount. The larger head allows for better distribution of forces, decreasing the risk of material damage, especially in softer or thinner materials.
Advantages of Big Head Screws
- Load Distribution: The increased head diameter spreads the load over a larger area, which is particularly useful in applications involving thin materials or larger holes.
- Versatility: Available in various materials such as stainless steel, carbon steel, and plastic, big head screws can be suited for both indoor and outdoor applications.
- Enhanced Grip: The design improves the grip on materials, making them ideal for applications where high shear strength is required.
- Ease of Installation: Different drive types like Phillips, Torx, and flat heads offer flexibility depending on the installation requirements.
