Seachoice RP-MP9696SC 1/4-20 x 5/8 Well Nut (2-Pack)

The Seachoice RP-MP9696SC well nut fastener provides a secure, watertight mounting solution for marine applications. This specialized fastener features a 1/4-20 thread size with a 5/8-inch length, designed to compress and seal when tightened, creating a vibration-resistant connection that won't loosen over time.

Key Features:

• 1/4-20 thread size for standard bolt compatibility
• 5/8-inch overall length
• Rubber body compresses to create watertight seal
• Ideal for mounting hardware on fiberglass, thin metal, and composite panels
• Prevents water intrusion and corrosion at mounting points
• Includes 2 well nuts per package

Well nuts are essential fasteners for marine installations where traditional nuts cannot be accessed from the back side. The rubber construction expands to fill the mounting hole when the bolt is tightened, eliminating the need for backing plates or access to the rear of the panel. Perfect for installing cleats, rails, electronics mounts, and other deck hardware on boats and watercraft.
