20Sets 1010 Series Aluminum Profile Connector,20pcs 1010 Corner Bracket,40pcs T-Nuts,40pcs Hex Screw Bolt and 1pcs Wrench,for T Slot Aluminum Extrusion Profile

First off I was impressed with the lightness of the brackets. At this price I was concerned that the screws might be soft metal but was pleasantly surprised that they are quite good quality. There was some material left from casting but that was very easily removed since the bracket material is pretty soft. They are a little fiddly getting them to sit correctly in the groove so sometimes I'd think one was set correctly and tight only to find it loosen later with movement of the rest of the structure. So, had to re-tighten entire assembly several times before it was truly solid. Good product though and one of the few vendors with brackets for 1010 series at a small fraction of what 80/20 charges.

Strong pieces to hold our 1” pieces of extrusion together in our sprinter.
