Remark:
The pole is a double aluminum pole structure. The internal screw with size M6 is used in the poles.
The anti-torsion of pole is 8Nm.
The torsion should be less than 8N m when used. The effective thread hole depth is 6mm.
Note: now we upgrade to LF280K with more than 6000 cycles and M6 threaded hole: LF280K
