Set of Stainless Steel Bolts M8 × 100 mm for Bilbao Filter Tank

The set of M8 × 100 mm stainless steel bolts is the original fastening hardware for the lid of the Bilbao filter tank, replacing corroded or damaged bolts from the original assembly. The stainless steel design guarantees resistance to moisture, chlorine and industrial chemicals without the need for surface treatment or regular maintenance. A correctly tightened set of bolts ensures even pressing of the lid against the seal and thus maximum tightness of the joint at all operating pressures. The 100 mm length corresponds to the height of the Bilbao tank flange and guarantees sufficient thread engagement even at the maximum prescribed tightening force. We recommend replacing the set together with the tank lid seal during regular annual servicing.
