An external spline is a series of ridges or grooves on the outside of a shaft or fitting that allows for torque transfer between connected components, typically used in mechanical applications like gears or couplings. In contrast, a Torx is a type of fastener characterized by a six-point star-shaped pattern designed to provide better grip and reduce cam-out compared to traditional screw heads. While both are used to transmit torque, external splines are primarily for coupling parts, whereas Torx is used for fastening.

You are probably needing a #12 external-torx.
A machine screw typically has a slotted or Phillips drive whereas a cap screw typically has a socket or torx head.

Torx is a six sided star shape used on bolts. Draw a hexagon or six sided shape and on the flat sides between the points draw a V half way to the center between each point. That is the Torx shape.
The sensor is held in place by one small bolt with an external torx head.

I believe it is a 12 point metric socket Not sure of the size though.
