Hands-free mutual rotation stopper - Japan Plarado

last updated:Mar 27, 2026

  • Official site

Hands-free even when facing down without falling! Prevents large bolts from rotating together, compatible with M20 to M100.

● Fixed with a stop screw, it won't fall even when facing down, allowing for hands-free operation! It effectively prevents large bolts from turning together. Since it's hands-free, "tasks that previously required two people can now be done safely by one person." ● Easily removable with just a hex wrench. It won't get stuck. ● One unit accommodates two sizes of nut across dimensions. ● No sparks are generated, making it usable in explosion-proof areas. ● Backup wrenches are large and heavy. Impact wrenches may not fit into narrow bolt spaces and pose a risk of pinching fingers during work. This anti-rotation stopper allows for compact and safe operation. Custom sizes and inch sizes can also be manufactured. ● Comes with a fall prevention wire and shackle.
