What distinguishes Lockbolt/Huckbolt fasteners from other tension and shear fasteners?

Lockbolt and Huckbolt fasteners are specifically designed with a unique locking mechanism that involves a locking collar that is crimped onto the tail of the fastener. This design feature provides resistance to loosening under vibration and dynamic loads, which is a significant advantage over other types of fasteners.

The number and design of locking collar grooves play a critical role in the effectiveness of this type of fastener. These grooves ensure that the collar properly engages the fastener when installed, resulting in a secure connection that can withstand considerable stress. This technical aspect is fundamental to their application, particularly in the aerospace industry, where performance and safety are paramount.

While other fasteners may have different materials, shapes, or coatings, it is the specific feature of the locking collar grooves that sets Lockbolt and Huckbolt fasteners apart and contributes to their reliability and integrity in tension and shear applications.
