24% failure rate best on t-nuts

24 failures out of 100, in other words I could clean some threads with a tap and make them usable, but I shouldn't have. Especially when the 76 drove nice and smooth.

Pros
  • t-nuts
Cons
  • bits and pieces

Good work! for fastener

Exactly as described and works great for retrofitting my 2020 aluminum extrusion 3D printer! Glides along the grooves and has no sharp edges to grab at the wrong moment.

Pros
  • T-nuts
Cons
  • Requires socket

Beware of ratings without a test report

These fall out. If you're looking for something 2020 extruded aluminum, this isn't it. Choose a traditional square corner. The hammer head makes you wish it were bigger so you can brawl with them for buying it.

Pros
  • fasteners
Cons
  • functionality
