In the world of fasteners, breakstem fasteners play a crucial role in joining materials quickly and reliably, especially when access is limited to only one side of a structure. These fasteners are a go-to solution in industries ranging from aerospace to automotive, and even in DIY home repairs.
What Are Breakstem Fasteners?
Breakstem fasteners consist of a tubular body and a mandrel (or stem) that is pulled through the body to expand it. As the mandrel is drawn in, it creates a bulge on the blind side of the material, effectively clamping the materials together. Once the correct tension is achieved, the stem snaps or "breaks" off—hence the name breakstem.
Key Benefits
Blind installation: Perfect when you only have access to one side of the workpiece.
Speed: They allow for fast assembly with minimal training.
Consistency: Provide uniform clamping and joint integrity.
Versatility: Available in various materials and sizes for different applications.
Where Are They Used?
Breakstem fasteners are ideal for:
Joining sheet metal in aircraft or vehicles
Assembling enclosures in electronics
Quick repairs in field service applications
Whether you’re working on a production line or fixing a metal panel in your garage, breakstem fasteners offer a secure and efficient fastening solution.
