Yes, can be directly set in the material, the basic material on the drilling, mainly used in the steel structure of the color steel tile can also be used for simple construction of thin plate fixed.
Q: Screw M is mechanical teeth, tapping is what?
Screw M is the outer diameter of the meaning, such as M5 screws, that is, the outer diameter (maximum thread diameter) of 5 mm screws
Q: How did the scrHow did the screw become round?ew become round?
Landlord refers to the screw head into a round can not be disassembled, you can use the saw in the screw head saw a slot, and then use a flat screwdriver can be removed, you can also use a pipe clamp to try, but the space to be bigger!
Q: Fasteners often say that the nature of galvanized oxidation is what it means
True color refers to the surface of the fastener is not any treatment, copper is copper color, iron is the color of iron, aluminum is the color of aluminum. Galvanized iron is the surface of the fastener coated with a layer of zinc, the role is rust. Oxidation refers to the surface of the fastener to the chemical reaction, to produce a layer of anti-rust film, the main role is rust, the other can also beautify the appearance.
Q: Install the shaft to install a few gaskets is appropriate?
As the frame five depending on the length, five links on the left side of the 68mm length of one and two on the right side, the length of the 73mm five on the left side of the right is not installed, install a washer, the thickness is the same as long as you can buy time, usually have three washers.

Q: I would like to ask the car transmission inside the thrust washer (thrust washer) is used to do ah?
Differential gear thrust washer is composed of silver alloy pressing, as well as plastics. Planetary gear thrust washer and half axle gear thrust washer shape are concave spherical and planar surface, there are many patterns like grooves or concave point in oil storage. The washer is the role of the friction reducing gear and axial differential housing, improve the transmission efficiency of the differential protection shell, thrust face not excessive wear, to prolong the service life of the differential housing, and maintain the normal meshing and transmission differential gear. The reason for the failure of the thrust washer is a serious lack of lubricating oil, or because of the small size of the stay and the erosion. Planetary gear broken, cross shaft fracture caused by the thrust washer damage, is generally rare. When the vehicle is traveling on a special road, or when the vehicle is in the mud, the differential frequency is used, resulting in excessive wear and thinning of the thrust washer. Thrust washer wear will make gear thrust surface shell, thrust surface acceleration loss, the differential gear axial shift, gear meshing clearance increases, the transmission space increases, causing the gear, cross shaft, differential housing bearing seat hole damage. Thus, the thrust washer is a reliable guarantee of differential action, but also to extend the life of differential parts. To this end, the vehicle should be updated on a regular basis when the thrust washer, to restore its proper clearance, to ensure the normal operation of the differential.
Q: how much Specification for washers
Conventional M3-M130, there is a "SP" large outer diameter M8-M36, in general, large diameter washers used for long hole or flange nut assembly
