Patent ID: 8689888

Claim:
A wellhead assembly comprising: an outer wellhead member having a bore defining a longitudinal axis, the bore having a first profile portion and an annular recess; a tubular inner wellhead member adapted to be lowered into the bore of the outer wellhead member; and a centralizer/overpull ring positioned on the inner wellhead member, the centralizer/overpull ring having a lower band portion and a plurality of resilient finger members extending upwardly therefrom, the plurality of resilient finger members each being separated from one another by a longitudinal slot extending from the lower band portion to upper ends of the plurality of resilient finger members, and the plurality of resilient finger members each being biased to expand outward with respect to the lower band portion to engage the bore of the outer wellhead member to center the inner wellhead member within the bore as the inner wellhead member is lowered through the bore, wherein the recess of the outer wellhead member is adapted to receive the plurality of resilient finger members and oppose axial movement of the centralizer/overpull ring to enable an upward test pull of the inner wellhead member.
