Before using expansion bolts, insert the bars on the expansion nuts into the gaps on the expansion sleeve. Otherwise, expansion bolts cannot be fastened.
The expansion sleeve of an expansion bolt must be flush with the mounting hole. If the expansion sleeve is above the ground, the cabinet cannot be installed properly.

Place an expansion bolt in a mounting hole.
Tighten the spring washer, flat washer, and bolt.
Hammer the expansion bolt with a claw hammer until the expansion sleeve is flush with the hole, as shown in Figure 2.
