【产品描述】压铆螺母柱又称压铆螺柱或螺母柱，是应用于钣金、薄板、机箱、机柜的一种紧固件，压铆螺母柱其外形一端呈六角形，另一端为圆柱状，六角边与圆柱状中间有一道退刀槽，其内形为内螺纹，通过压力机将六角头压入薄板的预置孔内（预置孔的孔径一般略大于压铆螺柱的圆柱外径）使孔的周边产生塑性变形，变形部分被挤入压铆螺母柱/压铆螺柱压铆螺母柱的退刀槽内，使压铆螺母柱铆紧于薄板上，从而在薄板上形成一下有效固定的内螺纹。【产品特性】◎板材背面保持完全嵌平；◎高抗扭矩阻力；◎装备方便，只需简单压铆；◎规格系列化，能满足多种设计要求。【产品材质】◎碳钢◎不锈钢【技术参数】公制压铆螺柱技术参数表螺纹规格Thread Size×Pitch材质型号Material Type最小钣厚Sheet ThicknessMin.钣孔尺寸Hole Size+0.08外径C-0.13对边HNOM.长度L+0.05/-0.13SteelStainless SteelM3×0.5SOOBSOOSOOSBSOOS14.24.194.755~20M3×0.6SOOBSOOSOOSBSOOS15.45.386.355~20M4×0.7SOOBSOOSOOSBSOOS16.05.9575~25M5×0.8SOOBSOOSOOSBSOOS1.37.27.1188~30M6×1.0SOOBSOOSOOSBSOOS1.38.758.72108~35美制压铆螺柱技术参数表螺纹规格Thread Size×Pitch材质型号Material Type最小钣厚Sheet ThicknessMin.钣孔尺寸Hole Size+0.08外径C-0.13对边HNOM.长度L+0.05/-0.13SteelStainless Steel.112-40SOBSOSOSBSOS.040.166.165.187.197~.787(#4--40)SOBSOSOSBSOS.040.213.212.250.197~.787.138-32?SOBSOSOSBSOS.040.213.212.250.197~.984(#6--32)SOBSOSOSBSOS.050.281.280.315.197~.984.164-32SOBSOSOSBSOS.050.281.280.315.315~1.378(#8--32)SOBSOSOSBSOS.050.281.280.315.315~1.378.190-32SOBSOSOSBSOS.050.281.280.315.315~1.181(#10--32)SOBSOSOSBSOS.050.281.280.315.315~1.378
