本厂也可根据用户要求设计、制造，以满足不同的螺纹规格及锁紧行程。
四、使用方法与注意事项
1.手动泵在使用前将液压油注满，注油口在手动泵的后端，打开螺母注油，注油后锁紧。加压时将泵上方的手柄上下压动，将泵右侧的卸荷开关手柄顺时针锁紧；卸压时将手柄逆时针旋转即可。左侧接压力表，可观察加压时的压力指示，手动泵前端接注油胶管。
2.液压螺母由螺母体、压环、注油口及放油排气接头组成，使用时将螺母外观清洗干净。螺母旋进工件并锁紧螺母，压环应在原始位置，然后将手动泵的注油胶管接口插在注油口上，锁紧手动泵右侧的卸荷开关手柄，慢慢加压，同时将放油排气接头上部的放气帽向内旋，放气，直至螺母内空气排净，流出干净的液压油后向外旋松放气帽使之单向阀关闭，继续加压注油，使压环向外压出，达到压紧目的，直到加压到你所需压紧目的即可。松开卸荷开关手柄，松开手动泵的加压胶管接头。
3.松卸螺母将放油排气接头向里旋转直至液压油流出，慢慢松开螺母即可。
4.螺母在没有旋进工件锁紧前，请不要给螺母加压，防止压环偏载脱出，在不使用时请将螺母内的油放净，压环回到原始位置，以备下次使用。在螺纹处加黄油防止生锈。
