stud bolts
| For connecting the fixed link function, the double headed bolt has a screw thread, of the screw, there is also a thick and thin, call: straight rod / shrink rod, also called double headed screw. | |
| Effect: | Generally used in mining machinery, bridge, automobile, motorcycle, boiler steel structure, hanging tower, long span steel structure and large construction, etc.. |
| Specifications | D=M12, nominal length L=80mm, performance to be grade 4.8 as long as the stud bolt full marks: GB/T901M12 x 80 |
| Anti loosing purpose | In the practical work, the external load has the vibration, the change, the material high temperature creep and so on can cause the friction to reduce, the thread vice in the pressure at a certain moment, the friction force is zero, thus causes the thread joint loose, if the action, the screw thread connection can relax and the failure. Therefore, must carry out the anti loose, otherwise will affect the normal work, causes the accident. |
