A hand tool for carrying out at least the screwing/unscrewing and/or percussion operations for boring, marking or punching, in particular on assembling means such as screws, bolts or pins. The hand tool includes at least one body attached to a handle. A tool-carrier rod is provided for carrying an impression corresponding to the operation to be carried out. An integrated means is provided for imparting an axial percussion in the direction of the tool-carrier rod. According to the invention, a shock rod is provided inside the tool-carrier rod and is capable of longitudinal movement for directly imparting the percussion force to the impression.

A container top punch apparatus which is suitable for forming an air pressure equalization opening in a beverage or other liquid dispensing container for equalization of air pressure between the interior and exterior of the container may include an apparatus housing. A punch assembly may include a punch shaft slidably disposed in the apparatus housing. The punch shaft may be retractable in a pre-punching position in the apparatus housing and extendable from the apparatus housing to a punching position. A punch spring may be disposed in the apparatus housing. The punch spring may apply a punching force to the punch shaft and normally bias the punch shaft in the punching position. A finger lever may engage the punch shaft. The finger lever may be operable to facilitate digital retention of the punch shaft in the pre-punching position and digital release of the punch shaft for deployment of the punch shaft from the pre-punching position to the punching position via the punching force, responsive to operation of the punch spring.

An orifice plate centering tool for use in centering an orifice plate includes a thin elongate member. A distal centering end is configured to contact the orifice plate. An opposed proximal end is configured to receive a force which is transferred to the distal centering end through the elongate member. A plurality of optional demarcations are provided along a length of the elongate member.

A marking apparatus and its method of use facilitate blind slide-mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. The apparatus includes a post element, a retention element, a tightening element and a cover. The retention element is movable against resilient bias to allow the apparatus to capture a mounting slot in the object. The resilient bias moves the retention element to a gripping position, and the cover can be rotated so as to cause the tightening element to secure the grip of the apparatus to the object. When the object is aligned with and pushed toward the mounting surface, the cover moves against an elastic bias to allow a marking end of the apparatus to contact the mounting surface so as mark the appropriate location for installation of a fastener to supportingly engage the slide-mount slot of the object.

A punch tool includes a body having a contoured profile configured for holding in a user's hand. The body includes at least one opening for receiving a user's digits and the contoured profile has at least one extension configured for contact with another of the user's digits. A strike portion for applying an external force is located at an upper portion of the body centered on a force line extending through the body. An impact portion is located at a lower portion of the body concentric with the force line and has an end tip configured to focus at least a portion of the external force to a work surface.
