1314 Series Steel Set-Screw Hub (5mm Bore)

This 5mm bore set-screw hub allows you to rotate a gear, sprocket, pulley, bracket or beam via a 5mm diameter shaft. Its steel construction combines compact design with excellent structural integrity.

Whereas most goBILDA® hubs have a 14mm diameter protrusion on their tops, this set-screw hub is flat, allowing you to utilize the rare instance of two middle holes located 16mm across from one another—an excellent opportunity for building with beams!
