Upgrade your assembly game with Orion Van Gear’s self-aligning 10 Series stainless steel roll-in T-nuts (1/4-20 thread), built for strength, precision, and corrosion resistance. Designed for DIY’ers, van builders, and professional fabricators, these fasteners make installing components on 10-Series aluminum extrusions faster, cleaner, and more secure. The perfect solution for securely attaching components to our Sprinter and Transit Roof Rack Crossbars.

Why Choose Orion Van Gear T-Nuts

  1. Premium 304 Stainless Steel: Built to withstand outdoor and rooftop use without rusting or seizing.
  2. Self-Aligning Groove Design: Dual grooves center the nut automatically for faster, more accurate installation.
  3. Ball Spring Retention: Keeps the nut firmly in place, even in vertical or overhead positions.
  4. Roll-In Access: Installs from either the side or end of the profile, perfect for areas where the extrusion ends are blocked.
  5. 8020 Compatible: Fits all 10-Series T-slot aluminum extrusions, including 1010, 1020, 2020, and our Sprinter and Transit roof rack crossbars.

The Original Stainless 10-Series Upgrade

When we first started, stainless steel 1/4-20 T-nuts didn’t exist - only zinc versions that quickly rusted on roof racks. We created the first all-stainless option for long-term durability, and have since upgraded it again with two precision self-aligning grooves that make positioning easier, faster, and more consistent. You won’t find these grooves on any other stainless 10-Series T-nuts.

Perfect for Any Project

Attach solar brackets, deck panels, corner brackets, hinges, joining plates, and more with confidence. Whether you’re building a roof rack, CNC frame, 3D printer, robotics setup, or custom fabrication project, these T-nuts deliver professional-grade reliability for any application.

FAQ (Frequently Asked Questions) click to expand

1.What are roll-in T-nuts used for?

They’re used to secure components to T-slot aluminum extrusions. Perfect for van builds, roof racks, and fabrication projects, especially where end access is limited.

2.What makes these different from standard T-nuts?

Ours are 304 stainless steel and feature both a ball spring and dual self-aligning grooves, giving you easier installation and better precision.

3.Are they compatible with all 10-Series extrusions?

Yes - fully compatible with 8020 10-Series and equivalent profiles, including Orion Van Gear roof rack crossbars.

4.Why stainless over zinc or carbon steel?

Stainless steel provides superior corrosion resistance, especially outdoors. Zinc and carbon steel nuts eventually rust; these won’t.
