Stainless machined M8 nut design to slot easily into any cross bar or outer bar on your ProSpeed Expedition or Expedition Aero roof rack. Can be used to mount ProSpeed and other aftermarket accessories. 

We recommend buying this version if you specifically want to mount things onto your roof rack outer bars, such as Sideloks and light brackets. If you want to mount things onto your roof rack cross bars there is a cheaper hex channel nut alternative. 

• Slots in anywhere along cross bars and outer bars
• A quarter turn positions the nut to grip firmly in the channel
• Machined from corrosion resistant 304 stainless steel

• 5/10x diamond nut
