BLIND RIVET FASTENER
The Hucklok blind rivet fastener, a structural rivet from Alcoa Fastening Systems, offers a quarter-inch grip range, allowing the product to join assemblies from 1/8 to 7/8 in. thick. The fastener's footprint, or "bulb", spreads the load over a broad area. The wider grip range is due to the shear ring. After the maximum clamp has been achieved from minimum to maximum grip, the shear ring breaks free from the pin and settles into the appropriate catch groove. The clamp is consistent through the grip range.
In addition, the fastener is double-locking, which means it securely locks assemblies from both sides.
