Application:
Outdoor equipment joints, stamping machines, medical equipment adjustment, etc

Advantage of Retractable Indexing Plunger:
Diversified thread specifications: Supports standard threads such as M10 and M12, suitable for compact or conventional installation needs
Rest Type and safety locking design (with locking nut or plastic knob) reduce the risk of displacement caused by vibration and improve the stability of heavy equipment.
Black zinc coating:
enhances wear resistance and corrosion resistance, suitable for conventional industrial loads;
Stainless steel polishing:
No additional coating required, suitable for clean workshops or food processing equipment;
Non standard customization: supports adjusting spring load, thread specifications (if non-standard), and knob materials;
