Built for Real-World Use Each T-nut is CNC-machined from durable 304 stainless steel for maximum strength and corrosion resistance. Dual alignment grooves guide the nut perfectly into place inside the T-slot, while the integrated ball spring holds it securely, even when working vertically or overhead. No more sliding, guessing, or lost hardware during installation. A Design First for 15 Series Builders When we started Orion Van Gear, stainless steel 1/4-20 T-nuts didn’t exist - the only options were zinc versions that rusted quickly on roof racks. That's why we created this all-stainless 15 Series T-nut for outdoor use. Fast, Versatile, and Compatible These roll-in T-nuts can be loaded from either the end or side of the extrusion, ideal for builds where the ends are blocked. They work with standard 1/4-20 bolts (not included) to attach solar brackets, deck panels, corner brackets, hinges, and other accessories to 8020-compatible aluminum frames. Perfect for van roof racks, solar mounts, CNC machines, 3D printers, robotics projects, and custom fabrication setups. Why Builders Choose Orion Van Gear Self-aligning groove design – faster, more precise installation Ball spring retention – holds securely in any position 304 stainless steel – rust-proof for outdoor and rooftop use Optimized for 15 Series / 8020 extrusions – professional-grade fit Trusted by van builders, makers, and DIY enthusiasts worldwide Whether you’re assembling an industrial aluminum frame, building a roof rack, or tuning your next CNC project, these stainless roll-in T-nuts are a reliable upgrade for every builder’s toolbox.
