The Workhorse of Any 40 Series Extrusion Build

These M8 Drop-In / Roll-In T-Nuts are an essential fastener for anyone working with 40 series aluminum extrusion profiles. Whether you're assembling a 3D printer frame, CNC enclosure, or custom rig, these T-nuts slide or drop into standard 40 series V-slot and T-slot extrusion channels for a fast, secure connection.

Drop-In or Roll-In — Your Choice

  • Drop-In: Insert directly into the open end of the extrusion channel
  • Roll-In: Slide into any point along the channel without disassembly — just position and tighten
  • M8 thread accepts standard M8 bolts and screws
  • Compatible with 4040, 4080, and other common 40 series extrusion profiles
