Drop-in fasteners can be placed directly into the T-slot to attach components—no need to disassemble your existing structure. They consist of a screw and nut.

Push-in nuts clip in to the rail and expand when you tighten the screw. Use them to install lightweight objects such as document holders.

Button-head fasteners are more compact than flanged-button head fasteners for use in tight spaces.

Spring and spring-tab fasteners hold the nut in place so it won't slide down vertical rails.

Spring-loaded ball fasteners hold the nut in place so it won't slide along vertical rails.

Fasteners with a handle are easy to grip and drop in place. The flexible rubber handle bends to fit underneath objects mounted to the rail.

Fasteners with stud twist into place. Tighten with a socket wrench.

Hammer fasteners drop in to the slot and turn into place when the screw is tightened. They're serrated to break the anodized coating on the rail, allowing static to dissipate.

Self-aligning fasteners have a ridge that keeps them centered in the T-slot.
