What Allen Wrench/Hex Wrench Fits the M6 x 20mm Screw on the Rhino-Rack # RRRLKVA?

Question:

On the Rhino-Rack 2500 legs, the horizontal security hex bolt size is 5mm. The security bolt attaching legs to aero cross bars is a bigger size. Not 5mm too small and not 6mm too big as I have tried both. Rack was purchased in 2015. My parts manual shows it also being a different size. Do you have available the wrench for the M6 x 20mm security screw?

I can definitely provide some clarification on what size hex wrench/allen wrench you need for the M6 x 20mm security screw on the Rhino-Rack 2500 Series Legs # RRRLKVA. According to my metric size specs, you do need a hex key of 5mm for the screw. It is possible that your allen wrench or the screw itself is stripped. One way to try to solve this is by trying both sides of the 5mm wrench for the screw.

If you discover that there is a possibility that the screw is stripped, the only way to get the screw out is by drilling it out.
