Your cart is empty.The MakerBeam T-slot nut is made of stainless steel and was specially designed to slide into the T-slot grooves of the MakerBeam aluminum profile (10mmx10mm in diameter). The MakerBeam T-slot nut is not compatible with MakerBeam XL or OpenBeam both 15x15mm in diameter. For these profiles that are 15mmx15mm in diameter there are other T-slot nuts available. The T-slot nut is great to fasten brackets or corner cubes. For these two purposes the nuts come with two types of bolts. The first type is a button head socket screw (ISO7380, M3, 4mm, A2) and is meant to be used with brackets. The second is the flat head countersunk socket screw (DIN7991, M3, 4mm, A2) and is meant to be used with corner cubes. Do note that because of the 4mm thread the load bearing capacity of structures will be limited. And be careful with the bolts that come with the corner cubes. 4mm or 6mm is hard to tell apart!

These are absolutely fantastic. They fit perfectly and let you use makerbeam just like the bigger aluminum extrusions. They are especially great for corner cubes and linear guides.

Very high quality / consistent tolerance (they're easy to slide in but not TOO loose, and very easy to thread the M3 screws into).

The product is great, except for how short the screws are :/, can’t really use it for anything on my project (I can use normal ones that come with the 20mm rails that are a few mm longer than the ones in this kit)I’d recommend them no problem but for the price I payed it’s not really worth it (and has room for complaint) but there’s really not many other options on amazon

Used with the straight brackets to butt join two Makerbeam rails together for a micro rail launcher. Very solid precision hardware. The sky's the limit ( as well as the size of your rocket motor).

The T Slot nuts are great for my MakerBeam set.Almost like the real ones for 80/20. Just tiny! They're definitely cute and it comes with plenty of screws.It’s a good set but boy is it expensive! It would have been nice if they included it in the standard set i bought.If you need them, then you have to pay the premium.

It's actually amazing that they can fit an M3 nut at this size. although it's hard to use (it screws into the extrusion) it keeps the profile very minimal, you literally cant find a smaller build system than this.
