Studless beams that can be connected using Technic pins and axles.
Studless beams began to replace Technic bricks with Studs in the late 90’s, beginning the transition of Technic into a distinct system of building from classic studded LEGO bricks. (Modern Technic sets have very few studded LEGO elements.)
