A blind stud, also known as a pull-up stud, is a fastener designed to provide strong external threads on metal surfaces when you only have access to one side of the material – hence, "blind" application.
Understanding Blind Studs
Blind studs are particularly useful in situations where welding or other traditional fastening methods are impractical or impossible due to limited access. They offer a robust and reliable threaded connection.
How Blind Studs Work
Blind studs are typically installed using specialized tooling, often spin/spin tooling. The tooling pulls the stud into the prepared hole, causing the stud to expand and securely grip the material from the inside. This creates a strong, permanent external thread.
Key Features and Benefits of Blind Studs:
- Blind Application: Installed from one side only.
- Strong Threads: Provides robust external threads.
- Easy Installation: Can be installed quickly and efficiently with proper tooling.
- Versatile: Suitable for a variety of metal surfaces and thicknesses.
- Permanent Fastening: Creates a secure and lasting connection.
Applications of Blind Studs:
- Automotive manufacturing
- Electronics assembly
- Appliance manufacturing
- Aerospace applications
- General metal fabrication
In summary, a blind stud is a specialized fastener providing a strong, accessible threaded connection in situations where access is limited to only one side of the material being fastened.
