    • A method for assembling captive screw includes the steps of providing an annular base and positioning an annular washer on a top of the annular base; providing a screw, a coil spring, and a sleeve; downward passing the screw through the coil spring and a top opening of the sleeve; and threading a threaded section of the screw through the annular washer, so that the annular washer is fitted around a shank of the screw to locate below the top opening of the sleeve and above the threaded section of the screw. An inner circumferential edge of the annular washer is not worn away by the threaded section of the screw threaded therethrough, enabling the annular washer to keep a small inner diameter for tightly fitting around the shank of the screw and ensuring reliable assembling of the sleeve to the screw.
    • 用于组装紧固螺钉的方法包括以下步骤:提供环形基座并将环形垫圈定位在环形基座的顶部上; 提供螺钉,螺旋弹簧和套筒; 向下穿过螺丝穿过螺旋弹簧和套筒的顶部开口; 并且通过环形垫圈将螺纹的螺纹部分螺纹穿过,使得环形垫圈围绕螺杆的柄部安装,以定位在套筒的顶部开口下方和螺钉的螺纹部分的上方。 环形垫圈的内圆周边缘不会被穿过螺纹的螺纹部分磨损,使得环形垫圈能够保持较小的内径,以紧紧地配合在螺杆的柄部周围,并确保套筒可靠地组装到 拧。
