These clamps worked better than expected. They are strong enough to hold all of my work pieces so far. I have a drill press with both T-track and large angled slots. An added bonus was that you can add a 1 1/4" washer to the bolt head and use them in the large slots of the drill press table and the washer can be stored on the bottom of the clamp when using the clamp in the T-track. This allows the clamp to get very close to the drill bit. This allows you to hold down very small work pieces.I would definitely recommend these clamps.
Love the item, love the Massca products. Everything I've got so far is made very well and durable!
I am 100% satisfied with these clamps. Will buy again when the need arises.
These clamps are quality clamps!
I love to do business with nice local people, they are great to work with.
