ST connectors refer to having a "straight tip", as the sides of the ceramic (which has a lower temperature coefficient of expansion than metal) tip are parallel -- as opposed to the predecessor bi-conic connector which aligned as two nesting ice cream cones would. Also has a mnemonic of "Set and Twist", referring to how it is inserted the cable is pushed into the receiver, and the outer barrel is twisted to lock it into place.

ST connectors have a key which prevents rotation of the ceramic ferrule, and a bayonet lock similar to a BNC shell. STs were predominant in the late 80s and early 90s.
