Bright Hexagonal Bright Bars
Hexagonal Bright Bars, commonly specified and ordered by their Across Flats (AF) size, are primarily used for components that require positive grip, easy tightening, and reliable assembly. The six-flat geometry allows tools to engage securely, making these bars especially suitable for parts that are frequently fastened, loosened, or assembled into systems.
Unlike round or square sections, hexagonal bright bars are preferred where functional flats are required directly in the finished component. This reduces secondary machining operations and supports efficient production of repeat-use parts such as fasteners, fittings, and connectors.
Consistent section geometry and controlled material selection help ensure uniform behaviour during turning, threading, and assembly, which is critical for high-volume and precision-dependent applications.
