This servo arm has equally spaced holes, 0.385” from one to the next in order to align with Actobotics Beams and other components. The holes are threaded to fasten an item to the top of the horn by installing a screw from the top side. They’re also countersunk so a screw can be inserted from the bottom while allowing clearance between the servo body and the arm. By threading a screw in from the bottom, you can slide a ball linkage or beam onto the screw, followed by a 6-32 locknut for a very reliable and robust setup.
