A floating captive screw installation method includes the step of inserting a lock screw through a spring member and then inserting the lock screw with the spring member into a stepped barrel, the step of inserting the stepped barrel with the spring member and the lock screw into a rotary cap to keep the head of the lock screw outside the rotary cap, the step of forcing a toothed engagement portion of the head of the lock screw into engagement with a retaining groove in the top open side of the rotary cap tightly, and the step of letting a front coupling flange of the rotary cap be stopped against the bottom side of a top coupling flange of the stepped barrel. This installation method eliminates a secondary processing process, saving much installation labor and time. |
