NG usage example [Cell Spacer Edition]! What if there is a 1mm gap between the cell spacer and the mounting components...? The manufacturer verified it themselves!
Press-in spacers used as support pillars inside the casing. What happens to the spacer if the convex side of the spacer is not in contact with the mounting member while tightening the bolt? The manufacturer of self-clinching fasteners (press nuts), "Sel Japan," has verified this! We provide a document summarizing the torque test results for both correct and incorrect usage examples. ★For details, please download the "NG Usage Example (3) / Spacer Breakage Edition" below★ ■Product Used DFB-M4-8S ■Test Conditions 1. The cell spacer is in contact with the mounting member. 2. The cell spacer is approximately 1mm away from the mounting member.
