Handiman / S&J 472 10-24 x 3/4 Well Nut Fastener (3-Pack)

The Handiman / S&J 472 well nut provides a quick and reliable solution for securing hardware when through-bolting isn't an option. Designed for 10-24 threads with a 3/4-inch grip range, this fastener is ideal for thin materials or applications where the backside is not accessible.

How It Works:

Well nuts feature a brass threaded flanged fitting surrounded by a molded rubber exterior. As the bolt or screw is tightened, the brass insert compresses and locks into place, creating a permanent threaded anchor. The rubber sleeve holds the well nut in position during installation and provides a protective barrier between dissimilar metals to prevent galvanic corrosion.

Key Features:

• 10-24 thread size with 3/4-inch grip length
• Brass threaded insert provides durable, corrosion-resistant threads
• Molded rubber exterior holds fastener in place during installation
• Flanged design prevents pull-through when tightened
• Creates permanent threaded insert that remains secure even when hardware is removed
• Includes 3 well nuts per card

Applications:

Perfect for marine installations including non-critical mast hardware, mounting brackets, electronics, and accessories where access to the back side of the mounting surface is limited or impossible. Also suitable for automotive, RV, and general mounting applications in fiberglass, thin metal, and composite materials.
