产品概述
压铆螺母外形呈圆形，铆接面带有压花齿及导向槽， 通过压花齿压入钣金预置孔位形成机械互锁从而固定于薄板。根据材质可分为 S、CLS、CLA、SP 四种类型。
S 型
- 材质：采用10B21型碳钢，表面镀锌；中性盐雾 48H。
- 性能特点：具有较好的防锈性能。
- 应用场景：适用于冷轧板。
CLS 型
- 材质：采用304不锈钢冷镦，表面钝化；中性盐雾 96H。
- 性能特点：具有更高的防锈性能和耐腐蚀性。
- 应用场景：适用于铜板、铝板。
CLA 型
- 材质：采用 6063型铝合金，中性盐雾 48H。
- 性能特点：具有较高的防锈和耐腐特性。
- 应用场景：适用于铜板、铝板。如有氧化要求,需用CLA螺母
SP 型
- 材质：一般采用410系列不锈钢；真空热处理，硬度 HRC38~48；表面钝化。
- 性能特点：硬度高，防锈性能一般。
- 应用场景：适用于不锈钢板。
