We mainly produce spools, which are used in the control valves that determine the direction of a process. Known as direction control valve, this is a type of hydraulic valve. A spool is housed inside a cylinder and moves to the left or right to switch the flow direction of the hydraulics. Spools play a vital role in operation control of a machine.

The nuts produced by Seira are fasteners that gain their locking strength through a press. Having the same movements as a crimp, these nuts are used in thin boards that screw cannot be inserted and in sections subject to force. Not requiring deburring and countersinking, these nuts provide a beautiful finish. They are mainly treated as low-current special screws.
