Upgrade your fastening system with our premium 15S Roll-In T-Nuts, designed for larger T-slot aluminum extrusions like the 1.5"x1.5".

Why Choose Our 15S Roll-In T-Nuts?

• Premium 304 Stainless Steel – Corrosion-resistant.
• Self-Aligning Auto-Grooves – Ensures precise positioning and prevents misalignment.
• Ball Spring Retention – Holds the T-nut securely in place, even when working with vertical profiles.
• Roll-In Design – Easily loads from the profile end or side, ideal for hard-to-reach areas and our Promaster Roof Rack crossbars.
• Optimized for 15S T-Slot Extrusions – Suitable for 15 Series (1.5") and 40 Series (40mm) with an 8mm slot.

When we first started, stainless steel T-Nuts for 15S extrusions didn’t exist—most available options were prone to rust. That’s why we developed these using 304 stainless steel to ensure durability and longevity. We’ve also enhanced them with auto-aligning grooves for better positioning and ease of installation.

Frequently Asked Questions (FAQ)

1. What are roll-in T-nuts used for?
Roll-in T-nuts are used to secure components to T-slot aluminum extrusions. They are ideal for DIY van builds, roof racks, industrial framing, and custom fabrication projects. Their roll-in design allows for easy installation from the side or end of the extrusion, making them convenient for applications where the ends are not accessible.

2. What makes these 15S T-nuts different from standard T-nuts?
Unlike standard T-nuts, our roll-in T-nuts feature a ball spring and self-aligning grooves. The ball spring holds the T-nut in place, preventing it from shifting during installation, while the auto-alignment grooves ensure precise positioning for a secure fit.

3. Are these T-nuts compatible with all 15S extrusions?
Yes! These 1/4-20 and 5/16-18 stainless steel roll-in T-nuts are fully compatible with 15S 8020 and equivalent extrusions. They are not compatible with 10S extrusions but we do offer 10s Tnuts here.

4. Why choose stainless steel T-nuts over zinc or carbon steel?
Stainless steel provides superior corrosion resistance, especially for outdoor and rooftop applications. Unlike zinc-coated or carbon steel alternatives, these T-nuts won’t rust, making them the best choice for van builds, roof racks, and heavy-duty setups.

5. Do these T-nuts come with bolts?
No, these T-nuts are sold separately in packs of 25 or 50. You will need to purchase 1/4-20 or 5/16-18 bolts separately based on your project requirements.

6. How fast is shipping?
We offer FREE shipping to the lower 48 states. Orders typically ship within 1-2 business days.
