Blind Bolt/Abrafast

About

Blindbolts function in numerous ways. The initial Blindbolt operated via gravity, utilizing a toggle which rotated around the axis of a non-load bearing pivot pin. It can be removed when needed and operates in both the vertical and horizontal positions. HD and TW bolts, meanwhile, operate as expansion bolts irrespective of orientation. This means that they can be used in any position and at any angle. There is also a Heavy Duty (HD) bolt which was created specifically to be used for structural connections, while the Thin Wall (TW) bolt is specifically for lighter steel frame connections.
