【Complete Metric Thread Repair Set】This kit includes a Counterbore x1, 1x tang break-off thread intallation tool, 1x twist drill bit, M11×1.5 HSS STI tap and stainless steel wire thread inserts (M12x1.5X16.2MM). All necessary tools are provided to repair stripped threads in one set.
【Restore Damaged & Stripped Threads】Effectively fix worn, cross-threaded and broken threaded holes. The wire insert creates a M12×1.5 internal thread, ideal for automotive engine housings and mechanical equipment maintenance.
【Stable Installation】The counterbore securely engages the insert driving tang to guide the wire insert straight into the tapped hole without distortion. The tang break-off intallation tool delivers concentrated impact to neatly shear the mounting tang after installation, clearing space for full bolt penetration and avoiding assembly interference.
