Replacement Carriage Bolt - M6 x 75mm

I looked for longer M6 x 75mm carriage bolts so I could use existing kayak cradles on the larger bars of my new Thule Xsporter Pro Rack. Local hardware retailers didn't have what I needed and neither did other online hardware suppliers. I was thrilled to find what I was looking for at etrailer.com. Pricing was great, delivery was prompt and follow-up customer service excellent. Now my new truck and rack are fully outfitted and ready to go. Thanks etrailer.com! 560299

I have a Nissan Xterra and the crossbars are quite thick. The longest bolts that came with my Thule kayak rack still were not long enough. These 3” bolts fit perfectly, plus they arrived a day earlier than predicted! 675348

I ordered a few 80mm M6 carriage bolts for a Thule 594XT Sidearm roof bike rack. Theses bolts are longer than the ones that were included with the bike rack and will accommodate the thicker cross bars on a new car. The bolts shipped and arrived quickly and in great condition. The bolts are what was expected and as pictured on etrailer.com. No issues. Thanks 849829

Needed this item to install the Thule hull-a-port kayak rack to my WingBar Evo roof rack. The original carriage bolts (65mm) were not long enough for the brackets to be fully secured. This did the job! 862880

The carriage bolt was shipped quickly and the product was proper length and thread as described though the shoulder, the square part under the head, was undersized as compared to the Thule original. This causes it to slip as it is tightened in the roof carrier supports. 218985

Thanks for reaching out. In terms of follow-up, the bolt still works ok, but the issue I mentioned in my review still remains. The square part under the flange is not the same size as the Thule original hardware. This still results in slipping as it is tightened.

I had searched everywhere locally for this specific size of metric carriage bolts with no luck. Since it was for attaching my car top carrier I looked on the etrailer site and found exactly what I needed. They arrived in a short amount and my project is now complete. 699477

I purchased these carriage bolts to attach my existing kayak carrier to my new Thule Aeroblades. The original bolts were too short for the new system. These bolts worked perfectly. 373794

These bolts fixed my problem and have held up with no problems.

Purchased a new vehicle and had to add thicker cross bars- thus my kayak J racks no longer fit as the carriage bolts were too short. Went to both big box retailers- no joy. Lucky enough to discover this company that had exactly what I needed at a very fair price. Came as promised with great customer service and work like a charm. It was great to be able to repurpose my racks for a couple dollars. 310615

My Thule Rooftop Cargo Box is 15+ years old and the carriage bolts had rusted so bad I used a bolt cutter to remove them. I searched local hardware stores and the big box retailers (HD & L) but no one had the pieces I needed to replace them. I resigned myself to adapting the attachments and rigging up something that would work. On a whim, I searched for Thule Replacement parts on the web (I know, I should have done that first) and eTrailer came up with exactly what I needed! Within a few days I had the parts in hand and the Cargo Box is good as new! I'll be coming back when it comes time order a hitch...eTrailer is a great find! 179077

I ordered this as a replacement for my Thule Adventurer but it is a little small compared to the bolts that came with the carrier. They worked though. 139205

They did the job. I took the Adventurer on a long trip with no worries.

Glad I could find on line, my local hardware store had nothing that I could use. 860406

I recently bought Thule Hull A Port racks for my Kayak. Somehow I misplaced (ok, lost) one of the bolts. I searched all over Charlotte looking for a replacement including old school hardware stores which say they carry everything. No luck. I came across your website and there they were! I ordered extra bolts just in case. Many Thanks!! 114408

Always great service 938503

product is made well and meets the spec ification 849070

I Needed 16: 6m x75mm bolts for my new car’s thicker crossbars and Thule kayak carriers. This was easy to order here, but impossible to get from any of my local retailers. Thanks 502457

I was so glad to find these available for Thule kayak roof racks...not something normally stocked at local hardware stores. Smooth and speedy transaction. 461460

Extra parts so I can use multiply Thule equipment on multiple vehicles at the same time. 787342

It is a perfect replacement for needing extended length bolts to fit Thule Kayak racks over newer roof rack bars. I originally had a 2003 VW Golf with OEM roof rack. Now I have a 2010 VW Golf that must have taller bars because when I went to put Kayak holders on it would not fit with longest bolts it came with. These bolts from etrailer fit perfect like original and can still use the original 3 wing knobs (nuts) with the bolt. 135563

I ordered these bolts as longer replacements for the stock ones that came with my rooftop box. They worked as expected and I'm now using the box on my forth vehicle since I purchased it. Apparently it lasts longer than the cars. More importantly to me though, is the service from etrailer. Stellar! I received my items quickly and within time to make a trip we had planned. Thank you! 266410

My Chevy removable roof rails (thicker than standard roof rails) required a longer carriage bolt for the Thule J-Racks I had for my kayaks.. Thule had 50 and 65mm length bolts but I had to search online for longer (I was able to use the hand tightening nuts that came with the racks, which is why I stuck with the 6mm diameter bolt).. was psyched when they arrived promptly using standard shipping and was finally able to haul my kayaks down to the bay to spend an afternoon with my teenaged son on the water.. Thanks guys.. 218542

Just what we needed and were unable to find locally. In fact, we really need 4 more bolts like those we ordered. I hope these arrive as timely as the first order. 848658
