RED WOLF 3/8-16 T-slot Nut Kit 10-Pack for Toyota Tundra & Tacoma — 304 Stainless, Button-Head Screws

RED WOLF 3/8"-16 T-slot nut kit is a 10-pack of stainless-steel T-slot nuts and button-head socket cap screws (with wrench) designed to mount cleats, tie-downs, racks and accessories into pickup truck bed rails without drilling.

This hardware set was engineered to let you attach cargo anchors and modular accessories to compatible bed rails quickly and cleanly. The kit includes ten 3/8"-16 T-slot nuts, ten matching button-head socket cap screws and one wrench, all made from 304 stainless steel for long-lasting corrosion resistance. Before ordering, measure your bed rail slot dimensions to confirm fit: this kit was cut to match rails approximately 7/8" wide with a 9/16" slot opening.

How do I know if these T-slot nuts will fit my truck?

Measure the width of your bed rail and the slot opening. These parts are sized for rails about 7/8" wide with a table slot of about 9/16" and use a 3/8"-16 threaded fastener; many Toyota Tundra and Tacoma models match these dimensions.

• Thread: 3/8"-16 standard
• Base footprint: 1-1/4" L x 7/8" W x 5/16" H
• Protruding section: 1-1/4" L x 9/16" W x 5/16" H
• Total height: 5/8"

What accessories can I mount with this T-slot nut kit?

The kit lets you fasten a wide range of bed-mounted hardware without drilling through the bed floor. Use the nuts and screws to secure D-rings, cleats, toolboxes, bike and motorcycle racks, cargo rails, or custom brackets into compatible rails.

• Install tie-down cleats and D-rings for cargo security
• Mount toolbox brackets or slide-in storage solutions
• Attach bike or motorcycle tie-down frames and cargo rails
• Fit hub lock brackets or custom mounting plates

How durable and corrosion-resistant are these fasteners?

All components are 304 stainless steel, chosen for mechanical strength and resistance to rust in outdoor, road-facing conditions. The button-head socket cap screws deliver a clean low-profile finish and the nuts are tapped through so bolts pass freely for secure clamping.

• Material: 304 stainless steel for corrosion resistance
• Button-head socket cap for low-profile appearance
• Full-length tapped nuts allow through-bolting
• Supplied wrench for quick installation and removal

How do I install these into my bed rail?

Installation is straightforward: remove the rail end cap, slide the T-slot nut into the rail at the desired position, align your accessory, then thread and tighten the button-head screw. The included wrench fits the screws for proper torque control.

• Remove rail end cap to access the slot
• Slide T-slot nut into position inside the rail
• Align accessory and pass through the bolt
• Tighten using the supplied wrench to secure the clamp

Who is this for: This RED WOLF T-slot nut kit is aimed at pickup owners who want a non-destructive way to add professional-grade tie-downs and modular accessories to their truck bed rails — especially Toyota Tundra and Tacoma drivers or anyone with similar 7/8" wide rails and a 9/16" slot. It suits DIY installers, fleet managers, overlanders and weekend riders who need reliable mounting points without drilling into their bed floor.
