RED WOLF 3/8-16 T-Slot Nut Kit for Toyota Tundra & Tacoma — 6-Pack 304 Stainless, Low-Profile with Screws & Wrench

RED WOLF 3/8"-16 T-slot nut kit is a stainless-steel mounting solution that slides into compatible pickup bed rails to secure cleats, tie-downs, toolbox mounts and accessories without drilling.

Designed for owners of Toyota Tundra and Tacoma pickup trucks (and other trucks with similar bed rail dimensions), this kit includes six 3/8"-16 T-slot nuts, six button head socket cap screws and a compact wrench. Each nut is machined from 304 stainless steel for corrosion resistance and reliable clamping, and the low-profile geometry fits most 7/8" wide bed rails with a 9/16" slot. The packaged parts let you add or relocate tie-down points, D-rings, custom cleats and rack hardware while keeping the bed floor intact.

How do these T-slot nuts attach to my truck bed rails?

The nuts slide in from the end of the bed rail after removing the end cap and then are positioned where you need a mount. Bolts thread through the nut to clamp accessories securely; the nut is tapped through so the bolt can pass completely. Installation is straightforward with the included wrench and requires no drilling or permanent modification.

• Slide into rail after removing end cap
• Position, insert bolt and tighten with supplied wrench
• No drilling — removable and reconfigurable

What are the exact dimensions and hardware in the kit?

The kit contains six T-slot nuts and six 3/8"-16 button head socket cap screws plus one installation wrench. Each nut has a base and protruding profile sized to fit typical cargo-bed T-slots and provides a total height for secure clamping. Check rail width and slot depth to ensure compatibility before purchase.

• T-slot nut thread: 3/8"-16
• Base size: 1-1/4" L x 7/8" W x 5/16" H
• Protruding size: 1-1/4" L x 9/16" W x 5/16" H; total height 5/8"

Which trucks and accessories are compatible with this kit?

These T-slot nuts are engineered for Toyota Tundra and Tacoma factory bed rails but will also work with other trucks that have roughly 7/8" rail width and a 9/16" table slot. They are intended to secure cleats, D-rings, V-rings, cargo anchors, small toolboxes and accessory brackets designed for T-slot mounting.

• Fits Toyota Tundra and Tacoma bed rails
• Also fits other rails ~7/8" wide, 9/16" slot
• Use with cleats, tie-downs, bike racks, and toolbox brackets

How durable and corrosion resistant are these components?

The nuts and screws are manufactured from 304 stainless steel, giving them solid resistance to rust and road salt compared with ordinary plated steel fasteners. The material and precision machining deliver consistent clamping force for repeated use and outdoor exposure. For harsh marine environments, consider additional protective coatings, but for truck bed applications 304 stainless offers long-term reliability.

• 304 stainless steel construction resists corrosion
• Precision threads for reliable torque and repeat use
• Button-head screws reduce profile and snag risk

Who is this for: The RED WOLF 3/8"-16 T-slot nut kit is aimed at pickup owners who want a flexible, no-drill way to add or move tie-downs and accessory mounts — especially Toyota Tundra and Tacoma drivers. It's also a practical choice for anyone with aftermarket bed rails that match the stated dimensions who needs heavy-duty stainless hardware that installs and repositions quickly.
