- Lighting: Heat sink attachment in LED fixtures
Installation Guide
- Drill Prep:
- Drill hole = shank dia + 0.1mm (e.g., 4.1mm for M4 rivet)
- Deburr hole edges to prevent scratching
- Insert Rivet:
- Place rivet through materials with head flush against surface
- Ensure materials clamped tightly (max gap 0.05mm)
- Tool Setup:
- Use semi-tubular rivet setter with flat anvil (match head angle)
- Select punch diameter = 90% of hollow dia (e.g., 1.8mm for M4)
- Installation:
- Apply steady pressure (M4: 800-1,000N)
- Bucktail should form 140-160° mushroom shape
- Inspection:
- Verify head is fully seated (no gap)
- Bucktail diameter ≥ 1.5x shank dia (e.g., 6mm for M4)
