Patent ID: 7614453

Claim:
A method of joining a body to a wellhead comprising: supporting the body on the wellhead having a first connection profile; and engaging the body to the wellhead by advancing a collet having a second connection profile that sequentially engages the first connection profile on the wellhead, wherein the second connection profile comprising first, second, and third teeth, wherein the axial distance from a first point on a first ridge surface of the first tooth to a corresponding second point on a second ridge surface of the second tooth is greater than the axial distance from the second point to a corresponding third point on a third ridge surface of the third tooth, wherein the axial distances of the second connection profile are sequentially different from corresponding axial distances between teeth of the first connection profile, and wherein the second connection profile engages the first connection profile on the wellhead in a sequential manner due to the sequentially different axial distances, such that the first tooth engages the first connection profile before the second tooth engages the first connection profile, and the second tooth engages the first connection profile before the third tooth engages the first connection profile.
