How to Install
- Drill the hole to the chart size and remove any burrs.
- Thread the rivet nut all the way onto the matching mandrel.
- Insert the nut into the hole so the flange sits flat on the sheet.
- Set — hold the tool nut with a spanner, turn the bolt until tight, then back the mandrel out.
Go steady on the last turn, especially with a drill — stop once it pulls up firm.
