The Mechanical Jar is used to provide the ability to exert increased impact on subsurface tools by either jarring up or down. It is typically used in conjunction with hydraulic jars where the desire or need to jar may be necessary.


Often called “Spang Jars”, they are composed of two interlocking links which slide very much in the same way as a slide hammer.
Like other wireline tools the Mechanical Jars come with a threaded pin and box connection of desired size.
