• Exhibition Displays: Quick-assembly hardware for modular shelving and booth structures.

Unlock New Capabilities (Project Evolution)

• Past Projects (Prerequisites): If you've been using glue or plastic brackets, you've likely dealt with "wobble" and structural sagging.

• Feature Upgrade: This metal hardware kit unlocks High-Torque Rigid Assembly. You can now bolt your frame together with significant clamping force, making it suitable for high-vibration motors.

• Effort/Requirements: Beginner. Only requires a 3mm Allen key for the M5 screws.

Virtual Technician & Assembly

• Safety Tip: Use a drop of blue thread locker if you are building a high-vibration machine like a CNC router.

• Assembly Step 1: Insert the M5 screws through the bracket holes.

• Assembly Step 2: Thread the T-nuts onto the screws (leave them loose).

• Assembly Step 3: Slide the T-nuts into the profile slots and tighten. The nuts will automatically rotate 90 degrees to lock.

Accessories

• Included: 1x 20x20 Aluminum Bracket, 2x M5 Button Head Screws, 2x M5 T-Nuts.

• Required Additional: 3mm Allen Key, 2020 Aluminum Profile.

Frequently Asked Questions (FAQ)

1. Are the nuts the "drop-in" type? Yes, they are hammer-head T-nuts that can be inserted anywhere in the slot.

2. Will this fit 2040 profiles? Yes, on any of the 20mm faces.

3. What is the screw length? Standard 8mm or 10mm screws optimized for 20-series brackets.

4. Is the bracket painted or anodized? It is a standard silver die-cast finish with a light protective coating.

5. Can I use these for 3030 profiles? No, the M5 hardware and bracket dimensions are for 20mm series only.

6. How much weight can one bracket hold? For static loads, a single bracket can support several kilograms; use pairs for heavy loads.

7. Is an Allen key included? No, you will need a standard 3mm hex key.

8. What is the material of the screws? High-tensile alloy steel with a zinc or black-oxide finish.

9. Can I use these on V-Slot? Yes, fully compatible with 2020 V-slot profiles.

10. Do I need to drill holes? No, this is a "no-drill" assembly solution.

11. Are these rust-proof? The aluminum bracket is rust-proof; the steel hardware is zinc-plated for corrosion resistance.

12. What if the T-nut doesn't turn? Slightly loosen the screw and try again; they require a small amount of "slack" to rotate in the slot.

13. Is it sold as a single kit? Yes, one "unit" includes one bracket and four hardware pieces.

14. What is the bracket thickness? Approximately 2mm to 3mm at the casting walls.

15. Can I use M4 screws with this bracket? The holes are sized for M5, but M4 with washers can work in an emergency.

16. Is it compatible with 1515 profiles? No, the bracket is too large for 15mm profiles.

17. Can I use this for outdoor builds? Yes, though for extreme environments, stainless steel hardware (sold separately) is recommended.

18. Is this stronger than the hidden L-joint? Yes, external cast brackets generally offer more surface area and rigidity.

19. What is the weight of one kit? Approximately 25 grams.

20. Does Probots offer a 10-pack? Yes, please check our "Bulk Packs" section for better value on large builds.
