  Most extension screws belong to non-standard parts
Non-standard long screws are non-standard screw parts, which also play a very important role in industrial construction
Non-standard screws can be applied in all walks of life
Most of the non-standard screws are used in the construction industry
Today, Zhejiang lengthening screw manufacturer ingenuity hardware will briefly introduce the types and application scenarios of non-standard screws:
(1) embedded screws are mainly used for hanging and fixing air conditioning pipes, water pipes, electric pipes, ceilings, etc

(2) torsion flat head non-standard screw can be used on cement concrete, brick wall and hollow brick to fix sanitary equipment
Precision screws are widely used in electronics, electrical, electrical appliances, furniture, mechanical equipment and so on

(3) internal forcing internal tooth non-standard screw is used for fixing marble, water pipe, electric pipe and angle iron

(4) sleeve type non-standard screws are mainly used for fixing sound insulation walls and sanitary equipment

(5) external forced internal teeth non-standard screws are mainly used for the hanging and piping of water pipes, electric pipes and air conditioners, as well as the fixation of various angle iron and section steel
Precision screws are widely used in electronics, electrical, electrical appliances, furniture, mechanical equipment and so on

(6) torsion casing non-standard screws are used to fix lighting, light steel keel (ceiling keel and partition keel according to purpose) and sanitary equipment

(7) hollow non-standard screws are suitable for fixing door frames, cabinet frames, bathroom accessories and wall decorations

From the above use scenarios of non-standard screws, the specification and strength of non-standard screws are higher than those of ordinary screw fasteners
Generally, like the above non-standard screws, when using and installing, it is generally necessary to punch holes of corresponding size on the fixed body, and then install the non-standard screws into the holes
After tightening the nuts, the non-standard screws can be used to connect the fasteners with the fixed parts as a whole
After the non-standard screw is tightened, it will expand
There is a big head at the tail of the screw
A round pipe with several openings is sleeved outside the screw, which is slightly larger than the diameter of the screw
When the non-standard screw is tightened, the tail of the big head is brought into the open pipe, and the pipe is punched large to achieve the purpose of expansion, and then the screw is fixed on the ground or wall to achieve the purpose of rooting
