Abstract
A tool adapted to be manipulated single-handed for providing a direct reading of the size of small objects, particularly nuts and bolt heads. The tool includes a pair of tongs which are activated by a thumb slide. The latter is disposed in a slot formed in a planar surface of the tool. Scales, such as SAE and metric, are placed on opposite sides of the slot in operative side-by-side relation. The thumb slide includes a pair of index projections on opposite sides thereof which overlie the scales. Movement of the thumb slide to the point of contact of the extremities of the tongs with the object to be measured, provides a direct reading of the size of the object via the projections and scale markings. The tool includes a lubrication chamber and applicator for use in lubricating couplings and fasteners.
