Used primarily with Thule roof-mounted carriers, this 3-wing knob fits over the threaded end of an M6 carriage bolt to help secure the rack to your load bars. Replacement hand knob twists on.

Hi everyone. It's Evangeline here at Etrailer. And today we'll be taking a look at our replacement part, which is the Thule M6 low hand knob for your Thule roof mounted carriers here at Etrailer. So this is a direct replacement knob for your Thule roof mounted carriers. And like what we have here is we have a kayak carrier, which is the Thule stacker, and you can see how we're using a knob for both the carrier itself, as well as the clamps used to clamp down the carrier. So if one of them gets lost, damaged, or is broken, this is what you would get to replace them.
This fits right onto your M6 carriage bolt, kind of like what we have right here. So if you don't have an M6 carriage bolt, this will not thread onto it and make sure that's what you're using to clamp down your roof mounted carriers. All you need to do is just pin it around the bolt. And that's pretty much all there is to installing this replacement knob. Now the thing about this wing nut is that the thread is kind of deep on the inside.
There is some space that you have to clear before it threads onto your bolt. So just to make sure that if you're using this to replace something lost, and you're not sure which bolt you need, or which replacement part you need, make sure you have enough thread on that bolt for this to fit onto. So from my experience of working with Thule roof mounted carriers is I definitely recommend picking up a couple of these as you get your accessory, just because it is really easy to lose these nuts because of once you do release them, I've dropped them several times onto our floor or on the roof of a vehicle. So just because of that, this is a great piece to have around as a replacement part for if you do lose, break or damage, your current knob that is on your roof mounted accessory. Again, this is designed for Thule roof mounted accessories.
This may or may not fit whatever other accessory you have, but as long as it has an M6 pattern on that fault, it probably will fit. And that was a look at our Thule replacement hand knob for your Thule roof mounted carriers. Again, this is the M6 low hand knob and you can find them here at Etrailer..

Fits perfect
Sunday night. Time to get the kayak racks on the SUV so we could leave early Saturday morning for our vacation. Oh..... no. Missing one of the wing nuts. It was getting dark, I asked my wife to check the garage to see if she could find it as I got the other three racks onto the vehicle. No luck finding the wing nut.
I jumped on the Thule site to see if I could order a couple of nuts. I found them and added went through the check out process to see how quickly I could expect these. Oh.... they'll ship in approx 5 business days.
I then went to Amazon.com thanking that I'd find a way to order them thru Prime. There they were 5 times the cost at Thule with 'free shipping' but no prime.
I then ran a quick google search and found my way here to etrailer.com. Reviewers noted and praised the quick shipping of parts and email updates from George. I opted for Priority Mail shipping to help them get here faster.
etailer did not disappoint! George notified me when they were shipped and provided a tracking number so I could see they were on the way and watch their progress. They arrived on Thursday!
Very pleased with this experience. etailer will be my first stop next time I need parts.
THANK YOU!!
I looked all over to find replacement parts for an older, but still useful X-Cargo clam-shell roof top carrier. Places like another online retailer had the part, but at an extremely high cost. I will come back to etrailer over and over based on ease of use and price!
Ordered parts for a Thule kayak rack. Parts were Thule and worked well. Also ordered replacement rubber buckle protectors for Thule straps as the rubber was deteriorating after many years of use.
This is the first survey in a long time, in which I am eager to provide a review! This was such a small order for Thule parts needed for one of our kayak racks. I'm amazed that there was no minimum required. The parts came sooner than expected, and have allowed for us to have a rack system that is as good as new.
Thanks to George for caring to do superb business for insignificant amounts. This will cause us to continue with etrailer.com in the future. You have been faithful in the small things, allowing for more substantial orders to come!
As usual, lighting fast order processing and shipping (and Great pricing). Always a pleasure to do business with.

This carrier is great. I have my power cords, camp chairs , and sunshades up there. Not a leak, even through this terribly wet summer we had.

Still works great...
This is a perfect replacement part. As a matter of fact K just returned from a 1,700 mile trip with my tandem kayak attached to mu cargo rack with these wing nuts. They did not loosen one bit. Everything was as tight as the day I put it on.
I highly recommend George and etrailer
Initially etrailer.com sent the wrong part, mistakenly sending the M8 instead of the M6. Once contacted they sent the proper part and didn't require me to return the original piece, which I appreciated. My only complaint was that the original shipping was very delayed due to low staffing, then there was the product error and as a result we were unable to use our kayak racks and were forced to rent kayaks because ours were sitting unused in the garage due to the delayed shipping and wrong products. So, these couple of inconveniences ended up being rather costly for us. That said, etrailer.com did do the right thing by us, it just took a while.
I have an old Thule bike rack and the plastic hand knobs were starting to break off of the stay bolts. The knew knobs have a threaded steel insert that hold the bolt better. I had to buy new bolts that were threaded all the way to the cap. Much stronger than the original ptoduct. I used 80 mm M6×1.0 stainless steel bolts and a little thread locker to keep the hand knob from loosening on the bolt. Thule makes M6 and M8 hand knobs, so make sure to size the one you have. The hand knobs were easy to find at etrailer with a good description and fast shipping.
Lost a knob on my Thule kayak rack - left racks on too long without checking tightness - my bad. Hunted for replacement and some spares. Googled around a bit and landed here - useful description and good price. Knobs fit like OEM equipment (which they well may be) and have served well over the past year. All good, zero complaints. Just a remineder, if you are going to keep your rack on all summer, tighten your knobs once a week!
I needed to replace knobs I lost on the Thule883 kayak carrier. These are exactly the same as the original knobs.

I would order these again if I need replacements in the future
They work great but were a bit pricey. Overall I am Satisfied with the purchase and they arrived quickly.
Perfect replacement parts to repair the deflector on my Thule carrier rack.

Fine - no issues. When I installed the wing knobs I added a little glue glob to keep from losing them on the road again I originally lost them as a result of vibration and wind -they loosened up
Worked exactly as described.
Great company. My order was processed and shipped immediately. I could even go online and not just see my order being assembled and processed, but they even provided the name and a picture of the employee performing that part of the job—very good experience.
This is an exact OM replacement part that was easy to find on etrailer.com. Although it is a part that needs to be replaced every few years it is hard to locate even on the Thule site. Price and shipping were good and the parts (I ordered extras) arrived as promised. I will definitely recommend this company and will return for rack or trailer parts.

Wonderful customer service and timely delivery!
Somehow, the side tensioning knobs on my Thule Stacker 830 came off while driving. I searched for replacement knobs and found etrailer.com (your SEO is stellar). They had exactly what I needed and so I ordered a couple extra. It was an easy ordering process, timely delivery and great follow-up to ensure I was satisfied with the product and service. They will be my FIRST stop for all of my camping/hauling needs in the future!
