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. T-slot nuts are also used with extruded aluminum framing, such as 80/20, to build a variety of industrial structures and machines. A T-slot bolt is generally stronger than a T-slot nut and hex head cap screw.〔 David Alkire Smith. ("Quick Die Change" ). 2005. p. 106. 〕 A heavy-duty T-slot nut with a M12 bolt is rated to support 10000 N (about 1 imperial ton).〔 item Industrietechnik GmbH. ("T-Slot Nut 12 St M12, heavy-duty" ). 〕 Profile 40x40 (40mm by 40mm, with 8 mm grooves) extruded aluminum profiles and the T-slot nuts to fit into them were developed for use in mechanical engineering in 1980 by item Industrietechnik.〔 item Industrietechnik GmbH. ("timeline: 1980" ). 〕 It is very similar to the "channel-and-groove design" used in some toys. ==References== * Erik Oberg et al. "T-Bolts, slots, nuts and tongues." (2008).
