I got this to pair with a metal pegboard also available on Amazon, and while this is listed as working for both 1/8th and 1/4 holes, it barely stayed in the 1/4s. When I went to bend the back of a 5 inch hook to get a more snug fit against the board, part of the piece snapped off with light pressure as if it had been soldered instead of welded. I wouldn't trust these to hold any sort of moderately heavy tool. What's worse, they are so cheap that the return shipping is almost as much as the hooks were originally. Still, I'd rather have my $2 back.
