钢丝螺纹套规格
3 安装
钢丝螺套装配操作第三步就是借助钢丝螺套专用扳手进行安装
在一般情况下应用手工安装器进行钢丝螺套安装。
钢丝螺套放入安装工具内 , 使安装柄嵌入导杆槽内转动安装工具手柄使钢丝螺套旋入螺孔 , 并使其距表面留有
0.25-0.75 圈空螺纹。
少量安装钢丝螺套时和M14×2 以上粗牙钢丝螺套安装时可采用“T ”型开槽或螺纹头简易工具安装 , 并注意不要在钢丝螺套安装柄上施加较大的轴向力以防“ 乱扣” 。
钢丝螺套安装后 , 为检查所形成的标准内螺纹孔精度等级 , 可用相应的级别塞规检验。
4 去柄
钢丝螺套装配操作第四步就是去尾柄
对有折断槽的钢丝螺套，旋入螺孔后应将安装柄去除，需用去柄工具。
通孔时 , 要将钢丝螺套安装柄折断 , 一般用冲断器对准安装柄 , 用 200g 左右的榔头猛打一下即可去除 , 对于M18×2.5 以上的粗牙钢丝螺套和M14×1.25 以上的细牙钢丝螺套 , 用尖嘴钳上下弯曲安装柄就能折断，然后将断下来的安装柄从螺孔中取出即可。

公制和英制螺纹对照表
公制和英制螺纹对照表
公制和英制螺纹是两种常用的螺纹标准。
公制螺纹用螺距表示螺纹的尺寸，而英制螺纹则用每英寸包含的螺纹数量表示尺寸。
以下是公制和英制螺纹之间的转换表，以mm（毫米）为单位：
1. 公制螺纹尺寸转换为英制螺纹尺寸：
- M = 0.63659 inches = 1.27 inches (公制螺纹)
- NPT = 0.30642 inches = 1 inches (英制螺纹)
- PT = 0.23624 inches = 1/4 inches (英制螺纹)
- NPSC = 0.29371 inches = 3/8 inches (英制管螺纹)
2. 英制螺纹尺寸转换为公制螺纹尺寸：
- 0.3048 inches = 0.64676 inches (英制螺纹)
- NPT = 3.14 * 0.3048 = 1.1304 mm (公制螺纹)
- NPSC = 3.14 * 0.29371 = 0.9919 mm (公制螺纹)
- PT = 3.14 * 0.23624 = 0.6096 mm (公制螺纹)
注意：上述转换表仅供参考，实际应用中可能因螺纹类型、材料等因素而有所不同。
在进行螺纹转换时，请根据实际情况调整。
