- Overview:
- A type of sheet metal screw known for its sharp-pointed end and deeper threads compared to other types.
- Features:
- Point: Sharp-pointed to penetrate materials more easily.
- Threads: Fewer threads per inch than type AB screws, with deeper threads designed for better gripping power.
- Material: Often used in stainless steel (18-8), particularly in marine environments.
- Applications:
- Preferred for use in various metal and non-metal applications, especially where a strong grip is needed.
- Common in the marine industry due to its durability and resistance to corrosion.
- Advantages:
- Better Gripping Power: The deeper threads provide superior holding strength compared to type AB screws.
- Durability: Suitable for use in harsh environments, such as marine settings, where resistance to corrosion is essential.
- Notes:
- Despite the Industrial Fasteners Institute labeling type A screws as ‘obsolete,’ they remain widely used and preferred in specific applications, particularly in stainless steel and marine contexts.
