Bought this to mount a BMW cargo box to my Thule AeroBlade vis the gutter mount. The thread pitch matched the BMW screw knob (M8 / 1.25) but the square head on the T-bolt rotates freely in the gutter making it hard to tighten. The BMW T-bolt was rectangular to prevent this. The saving grace with this bolt is that the bolt is slightly tapered near the head so it lightly catches on the track (barely). Not the best bolt to get to mount my cargo box but hard to even find a T-bolt with M8 / 1.25.


Way too expensive. $x.xx for a simple 5/16 bolt is utterly ridiculous.
I bought 12 to hold my ladder racks to my bed topper t-slot rails.
I went by the dimensions on the site but when I recieved them I found there is a pyramid shape on the underside of the t-slot head which will not be good for my aluminum slots as only a slight fraction will contact the inside of the slot. Very good chance of distorting my rail.

The listing description and pictures showed nothing of this.
$xx some dollars for a few bolts that are useless to me.


After attempting to grind down bolts to fit this non standard Trac Rac system, these bolts fit perfect !


Great, timely service at fair price.


Needed to replace the t-bolts on a Mini branded rooftop cargo capsule to fit Jeep Wrangle 2021 Mopar roof rack. These matched in threading, length, and diameter to both products. It would be great if whoever actually makes the rooftop and cargo accessories (Thule, Yakima, etc.) could be identified rather than going through the relabeling guessing game.


I bought these bolts to attach my Thule ski rack to the crossbars on my 2015 XC60 Volvo. While slightly long, the bolts do work and I have had no problems with them or their attachment to the crossbars. I'm thankful I was able to find these bolts because I was getting absolutely no response from Thule. Thank you etrailer.


Excellent rating. I ordered replacement parts for a Thule gutter-mounted rack. The parts arrived within a couple of days and were exactly what I needed. I highly recommend for those looking for parts and equipment. Customer service-oriented company for sure.


Hard to find but they had the part in stock. Great customer service!


I ordered these for my new Inno Aero rack and they fit perfectly in the crossbar slots. Excellent quality t-bolts!!


Hard to imagine writing a review for a t-bolt, but here it is: the ordered t-bolt was delivered on time and in good shape! I will say having access to a t-bolt meant I didn't need to replace my entire bike rack when I swapped cars which required a new roof rack with a different t-slot dimension-


The head on this is not 22mm as advertised, it's actually 3/4" or ~19mm and more rounded than stock Thule. This means that the bolt will freely spin when placed into a Thule, in my case Land Rover, T-Slot. I made this work by cutting a slot in the top of the threads to use a screw driver to prevent it spinning while tightening. Otherwise great to have these available.


These bolts fit my old locking knobs and are plenty long, however the square end is not a tight fit for the feet to clamp lock setup. They twist when near tightness, hence I use locking pliers to seal the deal. A little more square beneath the head would fit feet/clamps better.


Great replacement part for at DAC integrated trail RTT


It has worked very well and I thank you


This bolt was very difficult to source! ETrailer had them and swiftly shipped them. Terrific service, especially considering such a small order. Thanks!


Retrofitting a Sears Sport 20-SV onto new BMW X3 Roof rails. The parts arrived on time and worked perfect.


Exactly as described and helpful for mounting older style racks to aerobars


Was happy I could find replacement Thule parts at a reasonable cost. Very happy!


It was good doing business with you guys thank you


They were 8 "T" bolts. Just what I was looking for and the right length.


Good quality, fast shipping


Just exactly what I needed


This part works pretty well for me, my only comment is that the screw part (for lack of technicality) although longer, as I needed, is also thicker and will not fit the same hole-size the other gutter feet I had purchased (thinking they would be about the same).


exact bolt, knob and end caps for what I needed. A++


worked great no problems
