Four black anodised 4040 aluminium extrusions 600 mm long square profile

VEVOR

VEVOR 4PCS 4040 T-Slot Aluminum Extrusion 600 mm Black

SKU CH-RS0K-T7CS4

Set of four 600 mm 4040 T-slot aluminium extrusions with M6 and M8 grooves for 3D printers, CNC and laser builds

  • Product typeOther Appliances
  • Overall width3.94
  • Four 600 mm rails included for immediate builds
  • 6063-T5 alloy with anodized finish resists corrosion
  • Precision-cut burr-free surfaces reduce friction
  • M6 and M8 T-slot grooves accept standard hardware
  • 40×40 mm profile suits 3D printers and CNC frames

4-Pack 4040 T-Slot Aluminium Extrusion

This set supplies four 600 mm lengths of 4040 profile made from 6063-T5 aluminium alloy with an anodised finish. The European-standard rails suit DIY frames for 3D printers, CNC machines and laser engravers. Each piece measures 23.62 x 1.57 x 1.57 in and the pack weighs 5.84 lbs total.

Sustained structural rigidity under load

The anodised surface resists corrosion in humid or dry environments so the profile maintains its dimensions over long print or machining sessions. High-precision cutting leaves burr-free grooves that reduce friction on linear bearings and keep motion consistent without frequent re-alignment. The 6063-T5 temper provides reliable stiffness for repeated thermal cycles.

Centre-hole diameter decides accessory fit

A 6.8 mm (0.26 in) centre hole runs the full length of each extrusion and accepts only M6 or M8 T-slot nuts, pulleys and brackets. Builders needing larger fasteners or a different slot standard cannot use these rails without modification. The fixed 40 mm square cross-section also limits the maximum moment of inertia for heavy gantry designs.

Questions about this item

How much heat does the 6063-T5 aluminium profile generate when used continuously in a CNC frame?

The 6063-T5 aluminium alloy does not generate heat itself; it acts as a passive structural rail and dissipates ambient warmth through its anodized 40 mm × 40 mm surfaces.

Which T-slot nuts and fasteners must I already have to assemble the 4040 rails?

The 6.8 mm centre holes and 40 mm wide slots accept M6 and M8 T-slot nuts, so you need those nuts plus matching bolts or brackets before you can build.

Will the 600 mm black anodized extrusions align with older 4040 profile I already own?

Yes — they follow the European 4040 standard with identical 40 mm × 40 mm cross-section and slot geometry, so they mate directly with existing 4040 profile of the same spec.
