How Structural Blind Fasteners Work
Each Huck structural blind fastener is engineered with a unique set of features that deliver industry-leading solutions to common manufacturing challenges, from high-speed assembly, hole-filling, and water-resistance to needs for a wide grip, for welding replacement, and applications with one-sided access.
Installation is similar for each fastener type using our extensive line of Huck tooling and nose assemblies.
Huck structural blind fasteners insert through aligned holes of the materials being joined. The tool nose assembly grips the pintail, pulls the mandrel head towards the sleeve, causing the sleeve to expand or bulb on the blind side of the hole. This pulls the materials together, locks the mandrel and sleeve, and breaks the pintail flush with rivet head, all within a couple of seconds.
