Ancor Stainless Steel Cushion Clamp - 5/16" - 10-Pack

The Ancor Stainless Steel Cushion Clamp – 5/16" – 10-Pack is a marine-grade fastening solution engineered to secure hoses, cables, and wiring in saltwater environments where corrosion resistance is non-negotiable. Built from stainless steel with a cushioned design, this 5/16-inch clamp absorbs shock and vibration while preventing the chafing and noise that plague poorly secured rigging on active vessels.

Each clamp features a nominal diameter of 5/16" (8mm), 0.04" thickness, and 3/8" (10mm) width with an #8 screw for secure fastening. The cushion design isolates vibration from engine and propeller activity, a critical feature that extends the life of fuel and coolant lines subject to constant flex and movement. Operating across a wide temperature range from -50°F to 300°F, these clamps remain flexible in cold weather startups and resist thermal degradation in engine compartments. The stainless steel construction resists oils, acids, and saltwater spray—the three primary culprits that degrade standard steel clamps within a single season on coastal boats.

This 10-pack suits both weekend fishermen managing small outboard rigs and serious offshore operators running complex hydraulic and fuel systems. The 1/4" clearance mounting hole accommodates standard through-bolt installations on helm consoles, engine blocks, and transom structures. For anyone operating in marine environments—whether freshwater lakes, coastal bays, or open ocean—stainless steel cushion clamps eliminate the false economy of cheaper alternatives that rust through within months and require repeated replacement.
