BMX pedal thread pitch I found a bmx in the garbage and fixed it up but when went to replace the pedals bought the wrong size. I'm wondering if someone can help me out. I was testing the old thread in my socket set an it screws into a 15/32 inch socket.
Most pedal threads are 9/16&quot; with the left pedal being left-hand thread (ie backwards to normal)   Kids bikes might have 1/2&quot; axles or 9/16&quot;
There were some crazy metric threads used in the 80s but they were very rare and never took off.
Not sure how you got it to work into a 15/32&quot; other than that's vaguely close to 1/2&quot; suggesting a kid's BMX.
