A T-slot nut is used with a threaded clamp to position and secure pieces being worked on in a workshop.
The T-slot nut slides along a T-slot track, which is set in workbench or table for a router, drill press, or bandsaw.
[1] A heavy-duty T-slot nut with a M12 bolt is rated to support 10000 N (about 1 imperial ton at rest).
[3] The item aluminum framing system has since been expanded to include a variety of t-slot nuts that have been designed for specific applications.
The item system is very similar to the "channel-and-groove design" used in some toys.
