    T-Nut Iin-Line Fastener
    • Used for end-to-end connections of 40 mm and 50 mm series extrusions
    • Material: galvanized steel
  • Miter Fastener

    Miter Fastener
    • Fasteners for extrusions with miter cuts
    • Material: galvanized steel
  • Special Fastener

    Special Fastener
    • For mounting parts onto Robotunits extrusions where no holes are to be seen from the outside of the assembly
    • Material: galvanized steel, NBR
    • In contrast with all other Robotunits fasteners, this fastener requires drilling
  • Facts

    • Play-free, accurate and centrally aligned connections
    • No drilling or milling necessary
    • Equal strength on both sides of the connection
  • Benefits

    • 100 % repeatability
    • Quick and easy installation
    • Strength comparable to a welded connection

  • One slot size fits all

    • 13 profile shapes in 40 mm and 50 mm extrusion sizes simplify the application
    • large, uniform 14 mm wide and 14mm deep T-slot
    • same T-slot dimensions for all extrusions in the Modular Automation System
    • Post insertion of heavy duty Drop-in Nuts up to M8 possible
  • Maximum stability

    • worldwide unique play-free, accurate and centrally aligned connections
    • single fastener provides up to 4 tons of tensile strength
    • tubular honeycomb structure for outstanding torsion and load resistance
    • maximum stability for all your applications
  • One fastener, double value

    • two-sided fastener provides equal strength on both sides of the connection
    • twice the strength for the price of one
    • no additional connectors needed
    • strength comparable to a welded connection
  • Any hole drilled is one hole too many

    • all connections made without drilling or milling
    • maximum wall thickness in key areas
    • unlimited re-usability
    • for required hole an integrated location groove guarantees precise and straight drilling
  • Stability increases with every turn

    • every turn positions centering inserts tighter into the T-slot
    • absolutely play-free, accurate and centrally aligned connection
    • concave surface of extrusion guarantees durable vibration resistance
    • low fastener height saves space in your design
  • Inserting the drop-in nut

    • Simple and quick insertion of the drop-in nut into the 14 mm wide T-slot
    • leaf spring assembly protects drop-in nut against unintended movement, guaranteed contact surface
    • to position the the drop-in nut, just slide to stop position
  • Anything is possible - even post assembly

    • simple post-assembly integration of struts without dismantling the frame
    • easy repositioning of struts at any time
    • no cutting of existing structures
    • no surface treatment required
  • Save time, cut cost

    • minimum assembly time required
    • simple and quick selection of Extrusion and Fastening Technology
    • no measuring of boreholes and no drawings necessary
    • length of the extrusion is the only measurement needed
    • labeled and tapped extrusions allow immediate assembly
