   Overshot

Overshot

Releasing and Circulating Overshot is an external catch fishing tool designed to retrieve tubular items from the well bore. It is rugged, economical, and easy to use. Overshoots come with a wide range of available accessories. These fishing tools have proven to be the most versatile and reliable in the field.

Standard Components

Top sub - The top sub is the uppermost component of the assembly. It is equipped with a box connection, as specified by the customer, to assure proper make-up with the fishing string.

Bowl - The bowl is the major working component of the overshot. The upper end of the bowl is threaded for assembly with the top sub. The lower end is threaded for assembly with the standard guide.

Standard guide - The standard guide is the lowermost component of the assembly. It guides the fish into the overshot, allowing the internal gripping mechanism to properly engage and grip the fish.

Spiral Grapple - The spiral grapple is a left-hand helix that conforms to the inside of the overshot bowl. Especially hardened wicker threads assure a positive grip to engage the fish securely.
