EYPINS 20 Pcs Right Angle Bracket, 90 Degree Corner Brace Connector T-Nut Screw 3030 Aluminum Extrusion Profile L Angle Brackets for DIY Projects Silver

Although the product is of good quality, the quality control is poor. The description says "with M6 Hexagon Screws and T-Nuts" this is not what is provided and not on display. It is provided M6 bolts which screw into the insert. One of the inserts came with no thread so is unusable. I will now have to adapt my fittings so I can use these items rather than sending them back and ordering more causing even more pollution to the planet.

What you receive is NOT AS DESCRIBEDIt says they are 30mm wide - they are 28mm wide.It says they are 41mm long - they are 35mm longThe supplied screws WILL NOT FIT many 3030 channelsA 3030 channel is at most 9mm deepThe brackets are ~5mm deepSupplied washers are 1mm deepSupplied screws are 16mm long9 + 1 + 5 = 15mmThus, the 16mm screws will not tighten fully, as they hit the end of the 3030 extrusionI contacted the seller, and got some nonsense response - they did not sort it.Note that seller's other listing for 40x bracketsactually include 12mm screws (Not the 16mm that it says in the listing), but these screws will fit properly, and are the dimensions actually described.

Bolts too long so cannot be tightened enough.

Fast delivery great product. Was able to complete my mobile dust collection trolley. Really robust.
