Installation Method
1.1 Installation of snap-on tolerance adjuster
1) Manually press into the bottom sheet metal slot for positioning;
2) Align the holes of the upper sheet metal;
3) Insert the installation screw;
4) Use a fixed torque wrench to rotate the fastening bolt;
5) Screw in the fixing nut for tightening.
Due to the reverse rotation and lifting mechanism of the screw of the adjuster, it automatically fits the sheet metal surface during the tightening of the bolt, which plays a role in eliminating the gap between the sheet metal.
