This replacement Hex Key set includes four 5/16" hex keys for Yakima roof-mounted bike and boat carriers. Hex keys attach to bolts and help secure the carrier to your roof-rack crossbars.


I have an "experienced" Yakima rack system with an original basket case, lockjaw rack and tandem rack...more experienced than the average Yakima employee these days and while Yakima tried to help their website is pretty crummy and the customer service staff don't recognize the older products. Etrailer on the other hand has a great website, I found all the little things I needed to refurbish my components and the shipping is super-fast and very reasonable. I ordered bolts, hex keys and components for my railgrab towers and my system is good as new.

Can't recommend them highly enough.

Products were/are great. Allowed me to refurb and reuse my original Yakima rack system...


I have many friends who have Yakima rack systems for carrying boats, bikes, etc.
When a part is needed I tell them to contact I have always been very satisfied with not only the availability of parts, but with the prompt delivery.

Thanks for realizing that we don't always want a complete system that Yakima seems to think we do.


good price and worked perfectly to replace old style load stops no longer available


etrailer always has just the replacement and/or modifications parts I am looking for. Used these along with the Yakima Replacement 5/16" x 2-1/4" Bolt Package to make installing and removing my Raptor bike racks easier.


Well these are just exotic wingnuts for Yakima rack accessories, but it's really great that someplace like etrailer is around with this kind of small part in the inventory.


Yakima makes a good quality product which always works as advertised. has one of the largest inventory of Yakima parts that I have ever seen. If etrailer doesn't have it Yakima doesn't make it. Got good on line help.


These were the perfect parts. Best deal on the internet and they came very quickly. E trailer will be my first stop for all my recreational accsesories.

Still work great! I check them every couple of months and they are always tight!


A hex nut fell off my Yakima bike rack—possibly loosened by vandal or attempted theft on a road trip. I only needed 1 new part and these appear to be genuine Yakima parts so I was happy to find these and with quick service.


I lost a Hex Key for my Yakima rack. I found just what I needed
Ordering was easy, service was great, shipping was timely. Thank you!


Arrived promptly and the quality was A+!


Fit my Subaru branded kayak carrier that is no longer made so unable to easily locate replacement parts- misplaced the original hex bolt locks and thought i was going to be out of luck. Arrived within 4 days of placing the order and that involved a weekend.


Good to be able to find the Yakima bits & pieces to complete rack system that's been collecting dust in the garage for many years.


Just as described and nice to find somebody carrying Yakima accessories and parts. Will definitely be back in the future


The Hex Keys replaced the originals perfectly.

Fast service and fair price from,.

Still working!


Am glad you guys are out there, was able to get the parts I needed.

The only way you could improve would be to deliver to Canada. I had to route my order to my son in Tucson who then re routed to me in Canada.


missing part replacements


These are holding up very good and I use them at least one time per month going to slat water.


I was delighted to find these parts after several unsuccessful attempts at other sites. I appreciate the order being filled rapidly, too.


perfect as advertised


Items were correct and arrived as scheduled.


Perfect fit


Fast service, careful packaging.

  • Will Replacement 5/16 Hex Key Set 8810041 Fit with Yakima Raptor Aero Roof Mount Bike Rack
    The Replacement 5/16" Hex Key Set # Y8810041 that you referenced will fit the Yakima Raptor Aero Roof Mounted Bike Carrier Y02093. The only reason they aren't listed as a fit is because the Raptor Aero only requires one of the hex keys and the direct replacement for that is the Long Hex Key # Y8820028. Since both options use the 5/16" size though they are interchangeable on the Raptor Aero. I confirmed this with my contact at Yakima.

  • Replacement Mounting Kit for Older Yakima Lift Ticket Ski Carrier
    I checked with Yakima and my contact there believes the ski carrier you actually have is their older model called the Lift Ticket. They do offer a complete mounting hardware kit for this rack, part # Y8830033. The replacement hex key sets # 8810040 and # Y8810041 are for bike and boat carriers.

  • Replacement Hardware For Yakima BasketCase
    I did some looking around and we do offer the Replacement 5/16" Hex Key Set for Yakima Roof Mounted Bike Carriers # Y8810041 and the Yakima Replacement 5/16" x 2-1/4" Bolt Package # Y8880010 which will give you four bolts and four wing nuts, but not the square washer. Your best bet is to purchase the Replacement Hardware for Yakima BasketCase Roof Rack # Y8870043 which will include everything you need.

  • Replacement 5/16 Inch Knobs for Yakima SnapAround Mounting Brackets
    I pulled the parts you mentioned from the warehouse and the Yakima Replacement Luggage Knobs, # Y8870048, and the Replacement Capnut and Washer, # Y8810155, do not use the same threads as the SnapAround mounting bracket hardware, like part # Y8840018. The part you will need is the Yakima Replacement 5/16 inch Hex Key Set, # Y8810041.

  • Seeking Yakima Raptor Aero Bike Rack Square Bar Mounting Hardware
    To allow the Yakima Raptor Aero Bike Rack Y02093 to fit on square crossbars you will need the Yakima SnapAround Mounting Brackets (SNARs) - Round and Square (QTY 4) # Y8810135. These are confirmed to fit and work well with your Raptor bike racks and square bars. If you want the locks you can use the Yakima Accessory Lock Housing - Same Key System (SKS) Compatible # Y07220 (one for each rack) and then use the Yakima Same Key System (SKS) Lock Cores (QTY 2) # Y07202.

  • How to Carry a Trike on a 2007 Chevy HHR
    We do have some trike carriers that would likely work with your trike but the issue is the hitch. The trailer hitches for the 2007 Chevy HHR are all Class I hitches and the 2 carriers are designed for Class II or Class III hitches. The only way to carry the trike would be on the roof and it requires a little creativity. You would start with a roof rack such as the Thule rack using parts # TH712100 and # TH710401. Then you would need the Yakima Boa, # Y02065. that takes care of 2 wheels...

  • Bike Rack Needed to Transport a Recumbent Trike
    I do have a few options for you to carry a recumbent trike on your SUV. The first option would be to use the SeaSucker Roof Bike Rack for Trikes # 298-BD1005. You will simply need to place the Vacuum Cups in the appropriate places on your roof and pump them up until the orange band disappears. This has a 45 lbs weight capacity. Another option would be to use the Yakima Boa Roof Mounted Bike Carrier # Y02065 on your roof rack. For this to be compatible with your trike you will also need...
