2020 T-Slot Aluminum Extrusion Kit

This kit provides ten 1000 mm anodized aluminum profiles made from 6063-T5 alloy. It includes 21 pairs of M5 nuts and bolts plus ten cast aluminum connector blocks for immediate assembly. The set targets makers building 3D printers, CNC machines, or laser engravers who need a complete framing package.

20 x 20 mm Profile with 5 mm Center Hole

Each rail measures 20 mm by 20 mm in cross-section and features a 5 mm center bore for accessories. The T-slot grooves accept M4, M5, and M6 nuts, pulleys, and brackets without modification. This European standard dimension decides whether the extrusion matches existing linear motion components or printed parts.

Anodized Finish with Included Fasteners

The black anodized surface resists corrosion in humid or dry environments and requires no welding for assembly. Cast connector blocks join profiles at right angles using the supplied hardware, freeing the builder from sourcing separate brackets. The 4.5 kg total weight keeps structures light while maintaining rigidity for motion systems.

Questions about this item

How rigid is a 1000 mm 2020 profile when used as a frame rail?

The 6063-T5 alloy and anodized finish give a lightweight but stiff 20 × 20 mm rail; ten pieces weigh 4.5 kg total, so deflection stays low on typical 3D printer or CNC frames.

Which T-slot nuts actually fit the 2020 groove?

The groove accepts M4, M5 and M6 square nuts; the kit includes 21 M5 nuts with matching bolts for immediate assembly.

What clearance do the 5 mm center holes and connector blocks need?

Each profile has a 0.19 in center bore; the ten cast aluminum connector blocks bolt into the T-slots, adding roughly the block height without welding or extra machining.
