The HuckLok Blind Rivet Fastener is a high-strength structural rivet with an extended grip range. A shear ring permits assemblies from 1 /8 to 7 /8-in. thick to be joined. After reaching a maximum clamp force, the shear ring breaks free from the pin and settles into the appropriate catch groove. The fastener's large footprint, or "bulb," spreads over a wider area for a more durable and dependable joint. The double-locking HuckLok securely locks assemblies from both sides for added strength. The steel fastener comes in 3 /16 and 1 /4-in. sizes.
