Type L5020 Light weight keylocking threaded inserts

Installation process of bolt screw sleeve

1. Drilling: The drilling depth should be greater than the length of bolt sleeve. Note that the tapping drill size is larger than usual.

2. Tapping: The specifications of tapped threads should correspond to the specifications of external threads of bolt sleeves.

3. Installation: Screw the bolt sleeve into the corresponding threaded hole, and require the bolt sleeve to be lower than the workpiece surface.

4. Lock key: Press the bolt fixing key of the bolt sleeve into the bottom hole with appropriate tools.

Drilling and tapping are completely the same as machining common internal threads, and it is best to use special tools to improve working efficiency when screwing in and installing
