Dubro SKT HD Bolt Blind Nut 4-40x1 Tool - DUB129

The Dubro DUB129 4-40 x 1 heavy-duty socket bolt blind nut is a threaded fastener designed for securing components in RC aircraft builds and repairs. Blind nuts allow you to create a captive threaded anchor point in tight or inaccessible areas where a standard nut can't be reached from behind, making them a practical solution for airframe assembly and hardware installation.

Key Features

• 4-40 thread size suits standard RC aircraft hardware and servo mounting applications
• Blind nut design installs into a pre-drilled hole to provide a fixed threaded socket without rear access
• Heavy-duty construction handles the vibration and load demands of RC flying
• Compact size suits lightweight airframe structures without adding unnecessary weight
• Sold as a set, providing enough hardware for multiple installation points on a single build

What's Included

• Dubro DUB129 4-40 x 1 socket bolt blind nuts (quantity as packaged)

What You Need

• Appropriate drill bit for pre-drilling the blind nut installation holes
• Blind nut installation tool or appropriately sized bolt and socket for setting the nut
• 4-40 bolts or screws to suit your specific application (if not already in your hardware kit)
