Garbage. I used this for a month until the movable jaw broke. Absolutely useless. I didn't think it was very well made because the weight was so light. So I didn't tighten it, hammer it in, or do any other offensive things that you can normally do with a quality vise. But it still broke off when this user tightened it in his 60-year-old hand. Too heavy to send back so I threw them in the trash and started looking for old US made vise grips before the foundries took their products overseas and sold their good name. Do not buy Wilton or any other "American" brand younger than 40 years old! However, there is a premium for buying quality. live and learn
