Product includes: This is a metal expansion bolt mainly used for gypsum boards. The plastic box contains 45 self-drilling anchor bolts of 0.47×1.18 inches for gypsum boards and 45 flat-head self-tapping screws of 1.38 inches.
Installation steps: ① Use a hammer to drive the expansion bolt into the gypsum board. ② After ensuring the expansion bolt is flush with the wall, insert the flat-head self-tapping screw into the anchor hole. ③ Tighten the screw until it is fixed (as you tighten, the anchor bolt will automatically expand to achieve a secure hold).
