Martyr Anodes CMC04 Limited Clearance Shaft Anode with Stainless Steel Allen Head, Zinc

The Martyr Anodes CMC04 is a zinc shaft anode specifically designed for limited clearance applications where space is at a premium. This compact sacrificial anode provides reliable corrosion protection for propeller shafts in marine environments while accommodating tight installation spaces.

Key Features:

• Zinc alloy construction optimized for saltwater applications
• Low-profile design ideal for restricted clearance installations
• Stainless steel Allen head set screw for secure, flush mounting
• Sacrificial anode technology protects valuable shaft components from galvanic corrosion
• Easy installation and replacement maintenance

This shaft anode works by corroding preferentially to protect more expensive metal components like propeller shafts, struts, and rudders. The zinc composition makes it suitable for saltwater use, while the Allen head screw design allows for installation in areas where traditional hex nuts or external hardware won't fit. Regular inspection and replacement of shaft anodes is essential for maintaining effective corrosion protection in marine environments.
