It held the weight of my bike rack to my roof rack with my mountain bike attached for over 100 miles I’d say 5 star review worked as needed

  • Fits perfectly for what I needed
Color: M8x30mm,6pk
Bought this to mount a car awning i bought from amazon. This T slot bolts save my crossbar from being drilled. The washers that came with is was a plus, held everything together. Easy to use and fit perfectly in my yakima crossbars.

  • Very complete set, good quality
Color: M8x65mm, 8pk
So many washers and gaskets - very complete assembly. Good quality. Good material. Really wanted the shorter bolts, but all the kits with the shorter M8 bolts were delayed delivery, so I ordered the longer set. A bit of a project, but I cut them down, ground them flat and re-threaded the ends. The right length would have been easier out of the box, but I don't mind a little DIY. ... show more

  • These bolts fit my pop up camper roof tracks perfectly. Additional product dimensions in pictures.
Color: M6x65mm, 8pk
I bought these T Bolts to mount something to the OEM roof tracks on a 2010 Jayco Jay Series 1207 pop up camper. I didn't see the dimensions of the square part of the bolt in the product pictures or description info so I took a chance on buying them, and they fit perfectly! See attached pictures for the additional dimensions. I bought the 60 mm length bolts but presume other lengths have the same square dimensions. ... show more

  • What a bolt!

Great bolt does everything you ever wanted a bolt to do! It’s the boldest bolt I have ever used!

  • Too short for my setup, had to return
Color: M6x35mm,6pk
Key takeaway: Didn’t work for my setup. The bolts were too short, so I had to return them. Real usage experience: Tried using these on my roof rack cross bars, but the bolts didn’t have enough length to properly secure anything. Fit into the T-slot was fine, but they just didn’t extend far enough to be usable for my setup. Pros: * Fit into T-slots without issue * Threading seemed fine * Decent quality for the price Cons: * Bolts are too short for certain setups * Limited versatility depending on your rack/accessories Who it’s good for: Might work if you have a low-profile setup or thinner mounting points. Not ideal if you need extra length for platforms or thicker accessories. Comparison: Compared to other T-slot bolts I’ve used, these run shorter than expected. I’ve had better luck with longer variants that give more flexibility. ... show more
