1. A wellbore tool connection assembly, comprising:
a tool housing comprising a first housing region having a first outer diameter and a second housing region having a second outer diameter, the second outer diameter being larger than the first outer diameter;
a bias member channel provided in the first housing region and extending inward in a radial direction from a first outer surface of the first housing region;
a bias member provided within the bias member channel;
a snap connector engaged with the bias member such that the bias member biases the snap connector outward in the radial direction;
a recess extending inward in the radial direction from the first outer surface of the first housing region, the recess being bound by a recess wall; and
a retainer screw engaged with the snap connector and extending inward in the radial direction into the recess such that the bias member biases the retainer screw against the recess wall.
