Description
Six-Lobe / Torx barrel nut posts — also known as Torx female posts, Torx post, torx nut, 6-lobe security posts, 6 lobe, 6 lobe with pin, 6 lobe without pin, binding posts, tamper resistance post, Chicago screw posts, and sex-bolt posts — feature an internal thread designed to pair with a mating Torx screw for secure through-panel fastening. 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.
Six-Lobe / Torx barrel nut and screw fasteners are commonly as Door hardware posts, Restroom partition posts, Furniture and display posts, Architectural panel posts, Signage posts, Outdoor and recreational facility posts.
