Non - standard fastener processing screws in a narrow space for a wide range of USES


Non-standard screws are widely used in the assembly of electromechanical and light industrial products.If the nuts of a product need to be mounted on the outside and the interior space is small, the head of the riveting machine cannot enter the riveting and pumping.When the method can not meet the strength requirements, riveting and riveting are not feasible.Must be riveted.Suitable for fastening various thickness plate and tube (0.5mm -6MM).Pneumatic or manual riveting gun can be simultaneously riveting, convenient and firm;Instead of the traditional welding nut, it can make up for the thin metal plate, thin tube welding melt, welding nut is not smooth.

Small hexagonal rivet nut with flat head is mainly used for bolt connection of non-structural bearing force, such as connection of internal parts of railway passenger car, road passenger car, ship mooring, and modified rivet nut for preventing rotation of aircraft nut.It's better. It has the advantage of being lighter.The tray nut does not need to be riveted in advance and the rear space of the substrate can be used without any operating space.

The standard rivet nut is M3 M4 M5 M6 M8 M10 M12.In fact, M6 and M8 are recommended.Because the threads are small, they can be tapped directly on the substrate.If the thread is large, the weight of the bolt will be greatly increased.The increase of connection strength is limited, that is, the match is not reasonable.Non - standard fastener processing screws in a narrow space for a wide range of USES

1) embedded screws are mainly used for hanging and fixing air conditioning pipes, water pipes, electric pipes, ceilings, etc.

(2) twisted flat head non-standard screws can be used for cement concrete, brick walls and hollow bricks, and for fixing bathroom equipment.

(3) internal forced internal tooth non-standard screw, used for fixing marble, water pipe, electric pipe and Angle iron.

(4) bushing type non-standard screw, mainly used for fixing sound insulation wall and sanitary equipment.

(5) external forced internal tooth non-standard screw, mainly used for water pipe, electric pipe, air conditioner hanging pipe, as well as various Angle and steel fixation.

(6) twisted sleeve non-standard screw for fixing lighting, light steel dragon frame and sanitary equipment.

(7) hollow non-standard screws, suitable for fixing door frames, cabinets, bathroom accessories and wall decoration.

When using non-standard screws, first use a percussion drill (hammer) to fit the hole in the fixing body, then insert the bolt and expansion tube into the hole and tighten the nut to make the bolt, expansion tube, mounting piece and fixing body.The expansion between the two becomes one.When it tightens, it expands.There is a big head at the end of the bolt.The outer sleeve of the bolt is a round tube slightly larger than the diameter of the bolt.There are several openings in the tail.When tightening the bolt, place the end of the large head into the open tube.The pipe is enlarged to expand, and the bolt is fixed to the ground or wall to root.
