The mill bolt is used by mining companies to secure and fasten the mill lining, which reduces damage from the impact of the steel balls inside the mill.

It’s manufactured according to the client’s requirements, with a thread created by either chip removal or rolling. It has a black oxide finish and undergoes heat treatment with quenching and tempering.

Modepsa is the first Peruvian company in the industry to develop the M48 Rolled Thread Mill Bolt for SAG mills.

Rolled thread mill bolts have improved resistance to fatigue, shearing, and torque.
