DIN7504 Hex Washer Lange Head Self Drilling Screw

Q: Why the screw thread more closely, spin into the more effort?: Because the length of the screw into a certain, do a certain job. The more tight the thread, the equivalent of the longer the distance rotation, power = distance × force, long distance, the need for force naturally small

Q: Thank you for your support: The inner tooth type flat anti-skid pad is used in the mechanical combination to fasten the vibration resistant sealing components!

Q: I'm talking about another thing: Screw is the use of objects of the circular circular rotation and friction of the physical and mathematical principles, step by step to fasten the tools of the tools. Screws are the general terms of fasteners, daily oral language

Q: When do flat washers use GB95 when using GB97.1?: Flat washers are usually thin pieces of various shapes, used to reduce friction, prevent leakage, isolation, to prevent loose or disperse pressure. Such components are used in many materials and structures to perform similar functions. Due to the limitation of the material and the process of the threaded fastener, the supporting surface of the bolt and the like is not large, so that the surface of the connecting piece is protected by reducing the compressive stress of the bearing surface.

Q: Gasket 300HV relative to what material?: For the 140HV level can choose 08F, 08Al and 10, 10F, etc., the surface hardness can reach about 140HV

Q: A general set of screws have a few nuts, bolts, washers?: You want to see the specific requirements and uses. There is also a nut, a bolt, and a flat pad
