This rivet tool is highly durable and very straightforward to use. It fits steel and aluminum rivets from 3/32 inch to 3/16 inch and stainless steel rivets up to 5/32 inch.
It also has a feature that you don’t often see. It has a square shoulder fulcrum pin that is made from cold formed steel that is also heat treated. This is important as it means that it can prevent pin rotation so that users can be safe against hole elongation or even premature tool failure.
