A downhole assembly that includes tubulars rotationally coupled to one another. An interface is between adjacent tubulars that makes up at least a portion of the rotational coupling. Certain surfaces of adjacent tubulars come into contact with one another when adjacent tubulars are rotationally coupled; and which are defined as contact surfaces. Each contact surface is profiled with facets that are complementary to facets on a corresponding contact surface of an adjacent tubular. The profiling of the contact surfaces is such that when a contact surface is brought together with a corresponding contact surface; facets on the contact surface abut facets on the corresponding contact surface along planes that are oblique or parallel with an axis of the tubular. At least some of a rotational torque transmitted between adjacent tubulars occurs across the abutting facets.

Extendable elements of downhole tools are provided having an extension direction component perpendicular to a tool axis, wherein a force is applied to the extendable element when in operation. The extendable elements comprise a first cross-section that includes the extension direction component, a first surface configured to receive a first force component of the force, the first force component substantially perpendicular to the first surface and a second surface configured to transfer at least a portion of the first force component of the force to a body of the downhole tool. The second surface and the extension direction component perpendicular to the tool axis draw a first angle that is between 0&#xb0; and 90&#xb0;.

An apparatus for locking a transmission line in a tubular includes a first clamp segment configured to surround at least a portion of the transmission line of the tubular, the transmission line having a longitudinal axis. The apparatus also includes a second clamp segment configured to surround at least a portion of the transmission line, the second clamp segment and the first clamp segment configured to apply radial forces in opposite radial directions when the first clamp segment is engaged with the second clamp segment, the opposite radial directions being perpendicular to the longitudinal axis, the radial forces operating together to maintain the transmission line in a fixed position relative to the tubular and maintain tension in the transmission line.

A downhole tool includes a tool body having an inner surface portion and an outer surface portion. The outer surface portion includes a recess having a peripheral wall and an inner surface. A multi-chip module (MCM) housing is defined in the recess. The MCM housing includes one or more fortifying members that support axial and radial loading of the downhole tool and include one or more electronics receiving zones.

A downhole tool includes a tool body having an outer surface portion and an inner surface portion and a recess formed in one of the outer surface portion and inner surface portion. At least one removable electronic component access member is detachably mounted to the tool body. The removable electronic component access member provides access to electronic components housed in the recess. A metallic seal is provided on at least one of the tool body and the removable electronic component access member. The metallic seal prevents fluid ingress into the recess through the at least one removable electronic component access member.

A threaded connector that includes a pin end having external threads and a box end having internal threads that are complementary to the external threads has a thread profile that defines at least a portion of either or both of the internal threads and the external threads. The thread profile may include a thread root connecting a first flank to a second flank and the thread root may be at least partially defined by a plurality of tangentially interconnected radii. The plurality of radii may include at least a medial radius, a first distal radius on one side of the medial radius, and a second distal radius on the another side of the medial radius. The medial radius may be larger than the first and the second distal radius. Alternatively, the thread profile includes a thread root connecting a first flank to a second flank that is at least partially defined by a plurality of radii, each radius having a different length and each defining a circular arc.
