This article describes a method for clamping a component between two other components when zero clearance and zero stress are required in the assembled components. An assembly of three or more parts requires that the positions of all parts be maintained relative to one another. This is usually accomplished by clamping one of the parts between the other parts which can result, due to tolerances of the parts, either in a clearance or an interference problem. The first of these fails to maintain the parts in the proper relation; the second results in high stresses with consequent deformation, creep, or failure of the parts. To attain conditions of zero clearance and near-zero stress among the parts, the following approach can be used. Parts 2 and 3 are to be clamped together, capturing another part 4.
