Rotational mold inserts are dumbell-shaped inserts used in rotational molding to provide anchor points for other hardware such as handles and hinges. Rotomold Inserts come in a variety of shapes including mutli-collared, one-headed, square and hex. Threading covers a broad range of imperial and metric sizes as well as Pipe and SAE threads.

Sizing for the inserts is made by designating how many interior threads are required for the application. If you need a 1/4" of threading for an rotomold insert with 8-32 threads you would pick an 8 thread insert.
