I recently picked up this assortment of brackets and fasteners for my aluminum extrusion projects, and it’s exactly what I needed. The fit and finish are solid—no rough edges, clean cuts, and everything feels durable. One thing that really stood out (no pun intended) is that every screw comes with its own t‑nut. That saves a bunch of extra steps and trips to the hardware store, which is a relief mid‑build. And can I just say how awesome it is that they toss in an Allen key? It’s such a simple touch, but it means you can dive right into assembly without scrambling to find the right tool—or worse, spending five minutes wondering where your Allen keys disappeared to this time.I’ve used it for building a desktop enclosure and a small shelving unit, and it’s been perfect for both. The pieces lock together cleanly, and the t‑nuts slide into the channels smoothly. No stripped parts, no misfits—just straightforward, reliable assembly. If you’re working with extruded aluminum and want a grab‑and‑go kit that actually has everything you need (including the tiny, easy‑to-lose bits), this is it.

I recently purchased the 240Pcs 2020 Aluminum Extrusion Hardware Accessories kit, and I’m very impressed with the quality. The set includes various lengths of M5 screws, along with "T" nuts and slide nuts, making it the perfect addition for assembling or connecting 8020, 2040, and 2020 V-slot aluminum extrusion profiles.I primarily use these with the 2020 aluminum extrusion on my Creality Ender 3 3D printer. The material quality is excellent, and I’ve yet to find any flawed pieces. The T-nuts fit snugly, ensuring a solid and secure connection every time. I’ve used the kit on several projects, and everything works as expected. The assortment is just right—there's no surplus of unnecessary pieces, which keeps things neat and organized.The only downside was that the original case cracked at the hinge, but I had planned on moving to a separate hardware organizer anyway, so it wasn’t a big deal.Overall, I would definitely recommend this kit to anyone working with aluminum extrusions. It's a great value for the price, and the hardware is reliable for both beginners and experienced builders alike.

The storage case was a nice touch, and helps keeps the individual pieces seperated. My only two complaints are quality related. The black oxide coating (or whatever surface treatment they used) on the screws was very cheap/poorly applied and did not adhere very well to the base metal. Much of the "coating" rubbed off in my bare hands prior to use. If you're worried about rust, these may not be the best option for you in the long run.When it comes to the ease of use and overall functionality, the hex heads were slightly undersized. (Almost as if their broaching tool was excessively worn during production.) It wasn't a deal-breaker, but it was annoying. My brand new Bondus and Wera allen wrenches would not fit inside the hex unless I used the "ball" end of the wrench. (Yes I was using the correct sized wrench.) I'm sure if you were to use a cheapo Chinesium Allen wrench of dubious quality it would work better, but quality tools made to proper tolerances were too tight to be useful unless using the "ball" end - and even then the fit was snug. You could physically feel the ball end "snap" into place.For the money and speed of delivery, I can't complain too much. It's just a mildly annoying.

Good quality. Perfect fit.

Well-made and gets the job done.

Just look closer at size. Didn’t even need to break seal on container . I saw it was too small for my application.

Doesn't fit standard 2020 rail (20x20mm) which has about 5.3mm wide slots, only fits 2020V which is closer to 6.3mm wide slots
