Their six-lobe drive head provides excellent torque control and tamper resistance while maintaining a flush, architectural finish ideal for visible hardware applications.
Six-Lobe / Torx barrel screws — also referred to as Torx sex-bolt screws, 6-lobe security screws, binding post screws, 6 lobe screw, and Chicago screws (male posts) — are externally threaded fasteners engineered to engage with the barrel nut post. The Torx-drive design enhances torque transmission and reduces cam-out, making these fasteners ideal for architectural and public-access installations where strength, appearance, and anti-tamper performance are critical.
