A leadless biostimulator, such as a leadless cardiac pacemaker, having a header assembly is described. The header assembly includes a helix mount mounted on a flange. An inner surface of the helix mount conforms to an outer surface of the flange, and the outer surface has a non-circular profile such that the conforming surfaces interfere with rotation of the helix mount relative to the flange. The non-circular profile includes a linear segment, such as a radial segment, that resists rotational movement of the helix mount. The helix mount has a protrusion that extends into a recess of the flange to interfere with longitudinal movement between the helix mount and the flange. The protrusion is formed before or after mounting the helix mount on the flange. The interfering surfaces threadlessly interconnect the header assembly components. Other embodiments are also described and claimed.
