Martyr Anodes Limited Clearance Shaft Anode with Stainless Steel Allen Head Screw Zinc Anodes/Zincs

Martyr Limited Clearance Shaft Anodes are zinc propeller shaft anodes (shaft zincs). They protect your boat's shaft and underwater metals from galvanic corrosion and electrolysis damage in saltwater. The low-profile collar design suits tight spaces where a standard streamlined shaft anode will not fit. Each anode mounts with a stainless steel Allen head screw.

Key Features:

• Zinc construction: a sacrificial anode that corrodes in place of your shaft, propeller and other submerged metal components
• Limited clearance design: a slim collar profile for installations with little room along the shaft
• Stainless steel Allen head screw: a secure, corrosion-resistant fastener that is simple to tighten with a hex key
• Saltwater use: zinc is the standard anode material for saltwater environments
• Available in multiple shaft diameters: choose the child item that matches your shaft

Martyr Anodes is a well-known marine brand of sacrificial anodes. Replace the anode as it wears down to keep your running gear protected. This is routine maintenance for boat owners.
