The Spiro® Litelocker is a sturdy and advanced button lock machine. It enables up to 3 plates of sheet metal to be firmly joined together (cold
forming) without incurring any damages to the sheet metal surface. The press force is made by using a pneumo-hydraulic system. The result is a high quality joint solution that eliminates the need for screws & rivets and requires no coating treatment due to no corrosion.
