The better quality clamps usually have acme threads on the screws
I taught my students to use this style of wood clamp to hold small, irregular, or round pieces at the bandsaw for safe cutting. The clamp positions the operator's hands away from the blade, and provides a nice large handle for holding small or round pieces. They rest squarely and slide well on the saw table. If the blade happens to nick a clamp end, not a big deal, as there is no blade damage. "Clamps are wood, it grows on trees, we'll buy more!"
Seems so simple, but very useful tip. Thanks!
Useful tip! These clamps are great for holding thing vertical on the bench. This simple tip makes them even more useful.
