Self-Clinching Studs for Permanent, High-Strength Threads in Sheet Metal Assemblies

When working with thin sheet metal, creating durable, load-bearing threads can be challenging. That’s where Self-Clinching Studs provide a robust and space-saving solution. These fasteners offer permanent threads that withstand high torque, vibration, and repeated installation—without compromising the strength of the sheet.

At Dongguan Sango Hardware Fasteners Co., Ltd., we specialize in self-clinching studs for metal enclosures, communication equipment, electrical panels, and industrial electronics, delivering high retention performance and assembly efficiency.

1. What Is a Self-Clinching Stud?

A Self-Clinching Stud is a type of fastener that is pressed into sheet metal using a squeezing force, embedding itself permanently. The knurled or undercut groove of the stud displaces the surrounding material, locking it in place and creating a load-bearing threaded stud.

🔩 Key Benefits:

• Provides high-strength threaded posts in thin metal
• Permanently installs without welding, rivets, or loose hardware
• Supports high pull-out and torque resistance
• Maintains flush mounting on the opposite side
• Installs in seconds with a simple press-fitting process

2. Common Types of Self-Clinching Studs

🔹 Flush-Head Studs

• Head remains flush with panel surface after installation
• Ideal for tight-space electronics and clean exterior finishes

🔹 Non-Flush Head Studs

• Head slightly protrudes but offers greater retention strength
• Used in load-bearing brackets, frames, or machinery bases

🔹 Studs with Dog Point

• Tip of the stud is narrowed for easier component alignment
• Used in blind assembly positions or automated systems

🔹 Threaded or Unthreaded Studs

• Can be delivered with or without thread depending on application
• Common in grounding posts, support pegs, or boss mounts

3. Applications of Self-Clinching Studs

Self-clinching studs are essential in thin metal sheet assemblies that require strong, permanent fastening:

• 🧰 Enclosures and panels for telecom, electrical, and server systems
• 📦 Industrial equipment frames, support brackets, mounting points
• 🛠 Automotive panels and body frame connections
• 🧪 Medical equipment and instrument cases
• 🧱 Aerospace electronics, control boxes, and radar housings
• 💡 LED panels, displays, and modular housings

4. Material and Finish Options

Finish options:

• Zinc plating for corrosion resistance
• Black oxide for anti-glare and mild rust protection
• Passivation for stainless steel
• Nickel plating for conductivity and brightness
• Plain finish for cleanroom or special coating use
