Abstract
A small bore expansion plug having an inner wedge pin and a plug body with an outer hard surface with small, peripheral V-shaped grooves, a partly hemispherical end wall at its inner end and a tapered coaxial bore for receiving the wedge pin. To provide a radial expansion force within an acceptable tolerance between the plug body and the wall of its mounting bore, the wedge pin has a coaxial bore to form a high-strength spring and the plug body has a base material with a yield strength providing the desired plug body resistance to deformation.
