Martyr Anodes Clamp Shaft Anode with Stainless Steel Hardware Anodes/Zincs

Martyr Anodes clamp shaft anodes (also called shaft zincs or clamp-on shaft anodes) give propeller shafts dependable sacrificial corrosion protection. The anode corrodes in place of your underwater metals, so shafts and other fittings last longer. This product line is designed for easy installation and a secure hold on the shaft.

Key Features:

• Full shaft contact: A clamp insert gives a tight fit to the shaft for the life of the anode.
• Stainless steel hardware: Stainless steel hardware and lock washers are included.
• Bolt retaining washers: These keep the anode from falling off, so it is easier to install underwater.
• Slotted head hardware: The hardware comes with a slotted head, a lock washer and a bolt retaining washer.
• Material options: Anodes are offered in zinc, aluminum and magnesium to match your operating environment.

Choosing the Right Anode Material:

• Zinc is for saltwater.
• Aluminum is for saltwater or brackish water.
• Magnesium is for freshwater only.

Martyr Anodes offers these clamp shaft anodes in both imperial and metric shaft sizes. Choose the size and material that suit your boat and the water it runs in.
