4mm Ball Connector M2, model accessory, 5-piece

This 5-piece set of 4 mm Ball Connector M2 hardware adds a compact connection point to model mechanisms that rely on precise moving links. Each connector uses a polished spherical head above a short neck, hex section and threaded post, creating a clear interface for compatible snap-on or pivoting parts in tight installation spaces. The 4 mm head size and M2 thread make these connectors suited to small-scale mechanical layouts where clean movement and accurate mounting matter. The metal construction gives each piece a defined shape for repeated fastening and removal during setup, adjustment or replacement work. The hex base supports tool-assisted tightening, while the threaded post seats into matching mounting points for a secure mechanical hold. With 5 identical connectors in the pack, the set can equip several linkage positions in one assembly or replace worn hardware across existing running gear. On the workbench, these connectors fit naturally into repair, tuning and fresh build tasks where steering links, control rods or other articulated parts need a ball-end mounting point. The consistent dimensions across all 5 pieces help keep left and right connection points matched when a model uses mirrored hardware.
