E-z Lok EZ-M200 Self-locking Thread Repair Kit 33 Pc

Product Description

The E-Z LOK EZ-M200 is a 33-piece self-locking thread repair kit designed to restore damaged or stripped metric coarse internal threads in metal components. Each kit contains carbon steel threaded inserts that install into a drilled and tapped parent material, creating a durable locking thread that resists loosening under vibration and torque. The inserts cover four internal thread sizes ranging from M8 x 1.25 up to M16 x 2.00, making this kit a practical option for shops and field technicians who need to address multiple thread sizes without stocking separate kits. Licensed trades including HVAC, plumbing, and general mechanical contractors will find this kit useful for repairing threads in equipment housings, brackets, and structural fastener points.

This kit is suited for repair work on metal assemblies where metric coarse threaded fasteners have been stripped or cross-threaded. Typical applications include equipment frames, access panel hardware, pump and motor mounting points, and structural brackets found in commercial and residential mechanical systems. The M8 through M16 range covers the most common metric fastener sizes encountered in HVAC equipment, piping hangers, and electrical enclosure hardware. This is a bench or field repair kit intended for use by mechanical trades professionals working on production equipment or installed systems.

Installation Notes

Thread repair inserts of this type are installed by a machinist or mechanical trade professional using a drill, the appropriate metric coarse tap, and a separate installation tool not included in this kit. De-energize and lock out any equipment before beginning thread repair work on installed systems. Verify the correct tap drill size and tap specification for each insert size before drilling to avoid enlarging the parent bore beyond the insert's designed engagement range. Follow the insert manufacturer's installation sequence and torque the mating fastener per the original equipment specification after insert installation is complete.
