Abstract: In one embodiment, a vertical ratcheting anti-rotation device includes a ratchet mechanism pivotally coupled at a proximal end to a first tubular member in a first recessed area located on a shoulder of the first tubular member. A distal end of the ratchet mechanism includes a first plurality of angled teeth and a spring allowing the ratchet mechanism to pivot in a vertical direction within the first recessed area. The anti-rotation device may also include a toothed insert mechanically coupled to a second tubular member in a second recessed area located on a shoulder of the second tubular member. The toothed insert may include a second plurality of angled teeth positioned to engage the first plurality of angled teeth of the ratchet mechanism. The spring is compressible during coupling of the tubular members to allow the ratchet mechanism to move vertically over the second plurality of angled teeth.

Abstract: In accordance with embodiments of the present disclosure, a system includes a first tubular member having a first knurl surface and a second tubular member having a recessed slot located in the inner circumference of the second tubular member and a threaded hole from the external circumference of the second tubular member into the recessed slot. The system may further include an insert located within the recessed slot, the insert comprising a second knurl surface facing radially inward from the second tubular member and a set screw within the threaded hole of the second tubular member, the set screw having an unthreaded end mechanically coupled to the insert. The set screw rotatable to drive the second knurl surface of the insert into the first knurl surface of the first tubular member.
