Metric - metric fine

V-COIL thread inserts for metric coarse and fine thread

This series covers both metric pitches: the coarse thread for the normal case and the fine thread where preload has to hold. A thread insert restores a stripped thread and can give it a load capacity above that of the original. The stainless steel wire coil is screwed into the hole after it has been drilled out and re-tapped with the STI tool.

VÖLKEL offers 438 versions, from M 2 x 0.4 to M 52 x 3.0.
