1. Why Proper Installation Matters
Incorrect installation can lead to:
- Spin-out failure
- Reduced torque resistance
- Panel deformation
- Assembly rework
Even high-quality fasteners fail if installed improperly.
2. Correct Installation Process
Step 1: Hole Preparation
- Accurate hole diameter
- Clean edges
- No burrs
Step 2: Alignment
Nut must be perpendicular to the panel before pressing.
Step 3: Press Installation
- Use parallel pressing force
- Avoid impact or hammering
- Ensure full seating
3. Common Installation Errors
- Oversized holes
- Installing into hardened steel
- Insufficient press force
- Using incorrect tooling
4. Quality Inspection After Installation
- Visual flush check
- Torque test
- Spin-out resistance test
Conclusion
Following standardized installation procedures ensures maximum performance of SP self-clinching nuts and extends service life of sheet metal assemblies.
