MK Series Ribbed Threaded Inserts
Designed for use with Grade 5 of Metric 8.8/8.9 mating screws, Mk Threaded Inserts allow for virtually flush installation. This is due to the knurled body design and reduced profile head. In addition, with the MK Series, countersink drilling or dimpling of the parent material is practically eliminated. Installation is easy using our manual or pneumatic tooling.
Other MK design benefits include superior thread strength, outstanding corrosion resistance and prevention of thread dilation due to the increased cross-sectional thickness of the thread areas.
