Large-Diameter Strength for Demanding Applications
The Huck C50L® Lockbolt System is a heavy-duty fastening solution engineered for structural applications that require maximum shear and tensile strength. This large-diameter lockbolt delivers permanent metal-to-metal joints with exceptional fatigue life and vibration resistance, even under high dynamic loads.
C50L fasteners are ideal for demanding industrial sectors such as mining, transportation, construction, and heavy equipment manufacturing. The swaged collar design creates a consistent, high clamp load, providing long-term joint integrity without re-torqueing or maintenance.
Accufast supplies the full range of Huck C50L® lockbolts across Canada, with tooling support and fast shipping available for qualifying orders.
