Steel Wire Screw Sleeve,a new style screw fastener can be inserted into metal or non-metal materials to form a high strengthenning,wear-resistant and exchangable standard screw.It can aslo be used to restore the weard or damaged inner threaded holes .Steel wire screw sleeve is a threaded wire precisely formde by cold-rolling rhombus steel wire. It is the idensity of a inner therad with a radial crooked assembly handle in the one end.The diameter of screw sleeve in free state is slightly larger than the inner thread which it will be installed. During the installing,the twisting force added to the assembly handle by the assembly tools forced the diameter of ineroducing wrie to springly contract,when it is installed into the inner threaded hole,the screw sleeve can produce a expand force as a spring.So it can be strongely fastenned in the inner threaded holes. At this time,the steel wrie screw sleev is formed as a high precision inner thread with the intonational standard.The threa picth and angle errorm which is produced by uneven stress between the screw and thread hole can be balenced by the spring force of the steel wire screw sleeve . The steel wire screw sleeve can be divided by two styles of ordinery and locking as their operformances.Locjubg style srew sleevw also has the screw locking ability besides the all abilities of the ordinery ones.
