Huck® Lockbolts

Unlike any other fastener in the world, Huck® Bolts from Macros Fastening Systems are precision engineered two-piece fasteners that, once installed, never come loose. Even in highly vibration-intensive environments, Huck® Bolts deliver unmatched reliability and long-term performance.

Huck® Bolts provide direct metal-to-metal contact when installed, which eliminates the transverse vibration often found in conventional nuts and bolts. Engineered for a wide range of applications, Huck® Lockbolts by Macros Fastening Systems offer superior joining strength, shear, and tensile strength for an unmatched fastening solution.

In demanding structural and industrial applications, choosing the right fastening system is critical. A genuine Huck® Bolt installation delivers consistent clamp force and vibration resistance, making it ideal for heavy equipment, transportation, and infrastructure projects. Advanced Huck® Lockbolts are designed to provide superior fatigue strength compared to traditional fasteners. For applications requiring enhanced safety and tamper resistance, Huck® Bobtail Lock Bolts offer a pintail-free design that improves durability and long-term performance while reducing maintenance needs.
