What distinguishes Lockbolt fasteners in their design?

Lockbolt fasteners are characterized primarily by their unique design feature, which includes the number of locking collar grooves. These grooves play a crucial role in the fastening process, as they provide a means for the locking collar to effectively secure the fastener in place once it has been installed. The presence of these grooves allows the fastener to achieve a strong, vibration-resistant joint, which is essential in applications where reliability and strength are paramount, such as in aerospace or heavy machinery.

While the length of a fastener may vary based on application needs, it does not uniquely define lockbolt fasteners compared to other types of fasteners. Additionally, color can differ among various fastener types and is not indicative of their function or design. The material used in the construction of lockbolt fasteners can vary as well and, like length and color, does not distinguish them specifically from other fasteners. The number of locking collar grooves, however, is a definitive feature that sets lockbolt fasteners apart based on their intended performance characteristics.
