Arser S.r.l.

ARSER has been producing high quality threaded socket set screws for many sectors: general mechanics, agricultural mechanics, automotive, windows and doors, electrical engineering and much more.

ARSER also produces hexagonal keys in both standard and special lengths and threaded stud bolts.

The whole production process is managed in Zola Predosa (Bologna): a plant with over 40 special machines, entirely designed in-house, and two lines of heat treatment furnaces that allow us to produce special hardnesses in addition to the classic 45H.
