Replacement Square Head Bolt for Thule Fairings - 853-208909

Average Customer Rating:  4.9 out of 5 stars   (88 Customer Reviews)


Great product and exactly what I was looking for. Used this product to mount my Thule 593 Wheel On to my Yakima Whispbar on my 2013 Volkswagen Jetta GLI. Very simple setup and probably took about a total of ten minutes. I used this product along with the low profile wing nut that is already supplied with the Thule 593 Wheel On to maintain a clean look with no bolts or adapters visible. This setup will help with those looking for sun roof / moon roof clearance with low profile bars such as Whispbars and Aerobars!


this part is prefect for the modification I use it for in my metal work as I make these wheels and metal arms in my shop and need this part to fill a hole in the metal that is pre drilled in oval shape where I do not need it so this fits perfectly in there!


I have the Yakima Jetstream crossbars and just needed some M6 t-slot bolts, but did not want to buy the $20 Yakima Item # Y03098 with the extra plastic brackets. These Thule bolts fit the T-slot in the Yakima Jetstream bars perfectly.


Exactly what I needed to fit old accessories to my aerobars. I had a set of old Thule ski racks that I wanted to mount directly to the bars and not use the adapter "clamshell style" clamps. I slid these bolts into the T slot on the aerobars, put the threaded end through the bottom of the ski rack, then bolted them up with some washers and locknuts. I now have a lower profile ski rack, and they are more rigidly mounted to the crossbars.

I would suggest these bolts for anyone looking to mount non-standard things to your aerobars with the T slot. Just be sure to get the right bolts. I believe the threads are standard M6 threads.


Just as described.


Used to fit a Thule Pulltop 726 to Factory MB GLK roof bars (made by Thule) using channel mounting. The bolts were slightly too long and interfered with the pulltop functionality. I used a couple of metal washers for spacers to ensure a proper fit and to retain the functionality of the Pulltop.

Thank you for the comment! We do offer different lengths of the T-Bolts from different Xadapt kits, such as from the Xadapt2, it sounds like a shorter T-Bolt would have prevented the need for the washers.

Stock up on these T-bolts, not just for fairings. You can use them on any load bars with a slot that will take T-bolts. Fits my OEM Audi load bars perfectly. I use them for a Thule Big Mouth bike rack. No need to order the Xadapt 2 kit. This is a bargain at $1.00 apiece.

Still working really well one year later. A really good buy.

These are perfect for the racks that have a track to slide your accessories into. I bought a bunch of these and stuck them onto all of my accessories. Then I just grab what I need, and put it on the rack - no messing around with screwing this into each accessory. Why not - they are cheap.


Works with the T-Tracks well, and much more solidly connected than other footings. Use with surf racks to replace the strap feet. Now it is lower profile, less wind noise, and firmer connection. It is also fairly easy to remove with a ratchet, and is still locked to the roof when the rack is locked shut.


These fit perfectly in my Audi-branded, Thule-made roof rack. Weirdly the bolts for my BMW-branded, Thule-made roof rack were just slightly too wide. I wish the threaded portion of the bolt were a little longer, I'm using them in a 20-ish year old Thule Weekender box and the plastic strap holders that serve as the washers are pretty thick. These are long enough to work but another 1/8th - 1/4 inch would make them a bit easier to work with.


This is pretty much the universal "attach stuff to your base bars" bolt. I got these as a replacement bolts for my peloton bike rack and for my thule snowboard rack. They can also be used to attach things that are not thule, in most cases. Etrailer was great to work with.

Great for:
Audi OEM roof rack (produced by thule)
Peloton Bike Rack bolts
4 top Universal Ski/snowboard rack bolts


I used this to replace the strap feet for my Thule double decker surf/paddle board carrier so that they sit flush in my AeroBlade T-Track. Is much sturdier, quieter, and looks much better. I needed to cut the bolt shorter to allow the strap to fit inside the device, but was easy enough to do.


I bought these for use on my Thule-DeWalt truck rack. They will work, but the bolt is smaller diameter than the orignials. These may be made for the smaller Thule track racks.

This was the only place I could find the bolt heads to fit inside the track - so Thanks etrailer for carrying them, and especially for your fast service.

Etrailer also carries a stainless bolt that looks similar; I'll check out the diamter of this bolt to see if its larger.


A year has passed and these are still the same great quality product.


I used these fasteners to attach the third brake light to a 1999 BMW M Coupe. The square head fit perfectly. Once washers and bolts were secure, I used a Dremel tool to cut the bolt down. I found the bolt when using the phrase "BWM square head bolt" searching the Internet.

Fast delivery and cost-effective because the OEM part had to be shipped from Germany to the States at higher cost per bolt, higher shipping charges, and much longer wait time.


this is the proper bolt to utilize within the track of the Thule AeroBlades so that one can mount universal brackets to mount an ARB awning. Add a couple of washers and a nylox nut to complete this task.

Thanks to eTrailer for all their help and support.


Wow! Great price (absolutely the lowest I could find either via the internet or locally) and fast delivery. Super satisfied! I'm sure I'll be back!

Still working just fine!

Work good for me I heard he already had Factory roof rails on my truck canopy I was installing a solar panel and there's some weird size that fit the tracks9


Perfect screws to adapt my Thule bike racks to my stock 2016 vw golf roof racks.


Products work great. Etailer representatives were very knowledgeable and helpful in determining the exact parts I needed for my Thule roof rack. I would highly recommend tthem for their quick shipping, helpful insights and their expertise.


The square head bolt fit perfectly on the wind fairing. Make sure to buy the replacement 3-wing hand knob for Thule bike, board and ski carriers (used to secure it), because it comes separate.


Works perfect putting my attachments on my Yakima Whispbar rack! I'm so glad I found this site. Super helpful, quick and all those random parts you didn't know you ever needed but that make your life easier. Thanks!


The t bolts are well constructed but intended for something other than my thule basket as they are too long. The good news is a hacksaw resolves the issue quickly. As always etrailer has been exceptional with service, price and communication.


Fits my 2004 GTI OEM VW roof rack perfectly. I purchased these to mount custom and retrofitted accessories safely and securely. I know, for sure, that these t-bolts will fit all OEM VW roof racks from (At least) 1993-2021, regardless of car model.


Works as advertised. Good quality and well built. They look to be OEM Thule t-bolts.

These are in fact, OEM Thule t-bolts. We get our Thule replacement parts direct from Thule.
