Upgrade your roof rack mounting hardware with a stronger, more dependable solution built for serious touring.
Treklo Roof Rack Nuts are CNC-machined from solid 304 stainless steel to provide a premium alternative to common cast or plastic channel nuts. Designed to suit Rhino-Rack Pioneer 4, 5 & 6 platforms, Yakima LockNLoad systems and many other compatible roof racks, they simply drop into the rack channel before twisting into position as you tighten your bolt.
Whether you're mounting recovery boards, awnings, solar panels, rooftop tents or custom brackets, these heavy-duty channel nuts provide the confidence that comes from quality hardware. When your gear is travelling hundreds of kilometres on the roof of your vehicle over corrugations, vibration and harsh weather, every mounting point matters.
<>• Solid CNC-machined construction – Precision machined from solid 304 stainless steel for exceptional consistency and strength.
• Superior to cast hardware – Unlike lower-cost cast nuts, the solid machined construction delivers cleaner threads, improved dimensional accuracy and a more consistent finish.
• Built for touring – Designed for vehicles regularly driven on corrugations, rough tracks and long-distance off-road adventures.
• Larger contact surface – Broad bearing surface helps distribute load more evenly across the roof rack channel.
• Simple drop-in installation – Insert into the rack channel and tighten your M8 bolt to rotate and lock into position.
<>These channel nuts are designed to slide directly into compatible roof rack channels before rotating into their locked position as the mounting bolt is tightened.
Unlike plastic Zwifloc-style hardware, Treklo Roof Rack Nuts are manufactured entirely from solid 304 stainless steel, providing a premium mounting point for heavier accessories and demanding off-road environments.
Because they're CNC-machined rather than cast, every nut is produced to tighter tolerances with cleaner threads and a smoother finish. The machining process also reduces the surface imperfections and moisture traps commonly found in cast components, resulting in a cleaner, higher-quality part built for years of outdoor use.
When you're travelling with valuable equipment mounted above your vehicle, investing in quality mounting hardware simply makes sense.
<>• Greater confidence – Solid stainless construction provides a robust mounting solution for roof-mounted accessories.
• Better manufacturing consistency – CNC machining delivers precise dimensions and accurate thread engagement.
• Cleaner finish – Smooth machined surfaces reduce imperfections commonly associated with cast components.
• Long-term durability – 304 stainless steel resists corrosion in harsh outdoor environments.
• Built for vibration – Ideal for touring setups regularly exposed to corrugations and rough tracks.

• Rhino-Rack Pioneer 6

• M8 female thread – Compatible with standard M8 mounting hardware.
• Drop-and-twist installation – Quick installation without removing the roof rack.
