Review on 🔒 Swift-Lock Diameter Usable Length Fasteners: Unleash Efficiency with Quick Release Technology by Matt Heringer

I lost one and couldn't find a 5/16" (or 8mm) replacement. It appears that 1/4" (6mm) quick release pins are much more common. I bought 2 packs to have spares in case I lose another one. They fit perfectly and should last forever if not lost.
