        application of steel wire Lo sets (wire thread insert), referred to as sets of silk, is a new type of internal thread fasteners, usually threaded coil cold-rolled precision molding Diamond Stainless steel wire of high strength, high precision, smooth surface, high precision of internal, external threads for concentric body. Wire Lo sets a good after the formation of a line with the corresponding standards of high precision internal threads in the thread, its performance is better than the direct formation of taps power wire. Lo sets of steel after the installation of internal thread hole tolerance zone depends on the surface of steel wire thread Taoxing manufacturing tolerances and tolerances of steel wire Lo sets of mounting hole thread belt, the latter mainly depends on the power wire of steel wire Lo sets of installation precision of bottom, usually forming a 6H grade, precision is high up to 5H, the 4H level tolerance zone, a unified thread precision is 2B, 3B. Wire Lo sets of users can choose according to the band precission design special and tapping method required tolerances (hand tapping, machine tapping) and lubrication methods, to ensure your degree of inspection and use requirements.
