Teach you how to choose good quality steel wire spiral sets

Wire Thread Inserts is a kind of a screw inserts for non-ferrous metal thread protection and development, applicable to the threaded connection.Helicoil is widely used in aerospace industry, shipbuilding, defense industry, automobile industry and other industries.As steel wire spiral sets of the application of more and more widely, how to choose the suitable wire screw becomes especially important.
Steel wire selection is a screw should consider the following factors:
1, the shear strength value of the parent metal at the same level between the two values, should choose low.
Listed in the table 2, the shear strength of the numerical value of room temperature and under high temperature, the value is much smaller, when choose, should make the necessary calculations.
3, to ensure that the selected thread specification fully comply with the design standards.
4, screw the practical tensile strength, especially in the lower strength level, much bigger than the calibration of the ratings.To this point in the wire should be fully considered when the selection of a screw.
