The Huck® Magna-Bulb® is a premium clamp-style blind fastener engineered for exceptional shear strength and lasting structural integrity, even in the most demanding applications.

Its innovative shear ring design promotes consistent bulb formation and grip adjustment, allowing for flush break performance throughout the entire grip range. This ensures a secure and clean installation, regardless of the material thickness.

During installation, the Magna-Bulb's bulbing action spreads the load over a wide blind-side surface, creating a broad bearing footprint. This distributes force more evenly, delivering greater strength and high pull-out resistance, especially in:

• Thin or lightweight materials
• Oversized or misaligned holes
• Applications requiring superior blind-side strength

Additional performance-enhancing features include:

• A unique solid circle lock that maximises strength and provides exceptional vibration resistance
• Mechanical pin retention for structural reliability under load
• Flush breaks across the grip range, eliminating the need for costly cosmetic finishing
• Easy visual inspection to confirm correct installation

Whether used in transportation, construction, or industrial assembly, the Huck Magna-Bulb® fastener is ideal for applications where strength, reliability, and precision matter most.
