Abstract: A suspension nut for use in a wellhead assembly of an oil and/or gas well is provided. The nut includes a lower body portion threaded for connection to the wellhead assembly. It also includes an upper body portion adapted to support equipment in the well. The upper body portion is spaced from a surface of the wellhead assembly in the absence of force applied thereto when the lower body portion is connected to the wellhead assembly. The upper body portion is adapted to be forced into abutment with the surface in reaction to the weight of equipment supported by the upper body portion.
