For rivets already riveted and installed, the cutting value and tensile value are also specified in ifi-114 specification. Taking the stainless steel plate bolt as an example, the minimum shear strength is 260 pounds (1560 n), and the minimum tensile strength is 310 pounds (1, The technical engineers and interior designers know the minimum cutting value and tensile value of this stud. Therefore, the stainless steel double drum core pulling rivet can decide the total number of bolts to be used in commodity assembly, so as to ensure the inseparable fixation of the joint. In order to know the minimum cutting value and tensile value of the bolt in advance, the technical engineer and interior designer are able to There is no doubt that bolted joints are safe. Because the fracture of the bolt journal occurs in the special tool for riveting and installation, which exerts the anti support force or breaking load beyond the pre measured value, the operator only needs to press the bolt of the special tool for riveting and installation, and the rivet is riveted. The operator can not change the cutting value and tensile value of the riveted rivet when the journal is broken. The bolt is not like a small screw, which must be operated with reliable torque to fix a screw. If the torque of Lantern rivet is not enough or too large, we can not expect the bolt tight connection to have the same consistency as bolt riveting.
