An industrial long handled tool component system is provided having interchangeable tool heads, connectors, handles and grips. The novel connector system provides a polygonal locking bar concentric with a round outer reinforcing collar both engaged by a material connector insert and separated by plastic isolations seals. The novel connector promotes connection integrity and prevents joint movement. An alternate embodiment provides a connector system without the collar to save weight and manufacturing cost.
