The gasket increases the area of the force so that the object can be locked tighter, which in turn protects the work surface from scratches. You may notice that some parts of the hexagon socket screw, its washer can not be separated from the hexagon socket screw, that is, the inner diameter of the washer is small, smaller than the outer diameter of the thread, and then the outer diameter of the washer and the outer hexagonal screw head The path is the same. Such hexagon socket screws are not available in general hexagon socket screws unless they are ordered or obtained from bicycle manufacturers.
Then the same hexagon socket screw, unlike high-strength bolts, will have different torque values in different environments. The external environmental factors are: whether the thread is clean with or without milling, whether it is coated with butter, the material of the nut, the material of the locked object, these will affect the torque value of the lock, if you change a different material today The hexagon socket screws, for example, from steel hexagon socket screws to titanium alloy hexagon socket screws, the torque value will also change. Or if you change the handle of different brands and materials, then the hexagonal screw on your faucet, the torque value to be locked, will also change.
Simply put, the torque value is very important, but it is not static. Don't put the torque on the limit. Don't regard the torque wrench as the only standard. This is a fake science. It will only make you fall into the myth of tool and equipment. I understand the principles behind me and I think it will be more important.
Cheese head screws with washer daily maintenance points
First: There are white substances on the surface. This situation should be some phosphating substances. The main reason for this is that the fasteners are not cleaned or rinsed carefully when the fasteners are produced.
Second: In the process of quenching Cheese Head Screws with washer, be sure to use silicate to clean the surface impurities. Be careful not to leave any impurities on the surface.
Third: After the fastener is tempered, it needs to be soaked in ether for a period of time. If there is oily substance, it means that the fastener is not clean enough. This situation is mainly unreasonable when the fastener is heated, and there may be some small oxidation in the quenching oil.
