Price and specification of pop-up screws in Shaoguan, Shanwei, Meizhou [For inquiries and orders, please call Zou Haimei’s mobile phone, the largest supplier of stone dry-hanging accessories and curtain wall installation materials in Shenzhen, Guangdong, and direct supply to the construction site] The national standard of stainless steel pop-up screws is equipped with female pads, stainless steel pop-up screws The conventional specifications of screws include pull-out bolts, which are common expansion bolts. The expansion bolt is wrapped with a ring. There is a gap in the ring. When using it, a hole is made in the wall and the expansion bolt is placed in the hole. When the bolt is tightened, the ring is squeezed open so that the bolt gets stuck in the hole. When the screw is fixed, there is a section of the nut structure that can be deformed. When the screw tightens the nut, it uses the pulling force on the nut to deform the nut. At the same time, the nut is riveted to the workpiece. After that, the nut is fixed to the workpiece.
Expansion screw installation steps First, we need to drill a hole where the expansion screw is to be installed. The size and depth of the hole need to match the outer diameter of the expansion screw, so it is very important to choose the drill bit size when drilling.
Secondly, we need to install the flat washer and nut, then screw the nut to the bolt and end to protect the thread, and then insert the expansion bolt into the previously drilled hole.
Finally, we need to twist the wrench until the washer and the surface of the fixture are flush. Generally, after tightening by hand, tighten the wrench for three to five turns.
