Review on 180 Piece Rubber Grommet Assortment by InstallGear by Kevin Carr

Designed for SAE drilling in thin sheet metal, very narrow gap. Metric holes don't work very well and will pull them out if you pull something through them. The SAE holes fit snugly and they stay in place. The case broke open upon delivery leaving the sockets all over the place and some lost through a hole in the crumpled box. Wasn't thrilled but what to do with rude native speakers otherwise it's ok for what they do in a pinch.
