Product overview

The STEAM AK4060C is an orange ball link set for AK400/420 helicopters. Each link incorporates a thread-depth inspection hole, while stainless steel anti-burst rings reinforce the assembly. The set contains four orange ball links measuring M3.0×Φ4.5×Φ4.8×19.0mm and four Φ5.0 stainless steel anti-burst rings.

The ball links accept Φ2.5mm threaded mounting rods. Installation requires an effective screw engagement depth greater than twice the screw diameter.
