產品說明
| 此為擠壓式螺母，預先在金屬板件上開孔沖壓，問世已超過60年歷史，至今已發展出多款材質及牙路，滿足不同族群的需求 |
| Self-clinching nuts are installed by placing them in properly sized holes in sheets and applying a parallel squeezing force to the head of the nut. The sheet metal surrounding the head cold flows into an undercut thereby making the fastener an integral part of the sheet. A serrated clinching ring prevents the fastener from rotating after installation. |
