100x ZYLtech Hammer Nuts (T-Slot) for 2020 Aluminum Extrusion - M4 or M5

Fairly standard hammer nuts

These are good quality hammer nuts, no complaints with the product itself. Each package is labelled. My only hesitation is that sometimes these can tighten without actually engaging the t slot, but that's just the drawback of this type of nut. I'd like to have purchased some sliding nuts, but I think these will work well.

These worked perfectly and the price was great!

Another good product from Zyltech. Nice threads and long enough where you will not strip them out
