Metric Heavy Duty & Thickwall Keensert® Style Key Locking Inserts in Nitronic 60 – KNHM & KNHML Series

Looking for Metric Heavy Duty & Thick Wall Nitronic 60 Key Locking Inserts?

The metric Heavy Duty (KNHM and KNHML) Keensert® style threaded inserts series, made from Nitronic 60 stainless steel, are uniquely designed to offer exceptional resistance to galling, wear, and corrosion in thread repair and reinforcement solutions. Nitronic 60’s standout properties give these inserts a significant advantage over traditional stainless steels, especially in aggressive environments like chemical processing plants and marine applications. Its ability to withstand wear under sliding conditions and exposure to harsh chemicals makes these metric inserts an ideal solution for industries where longevity and thread reliability are critical. The KNHM series, being non-locking, provides secure and durable fastening in applications where vibration resistance isn’t a priority, making it a strong choice for heavy-duty machinery and equipment repair. On the other hand, the KNHML series, featuring a self-locking mechanism, is designed to resist vibration-induced loosening, making it particularly well-suited for aerospace or automotive applications, where parts are constantly in motion and require extra fastening security. Both series benefit from the superior mechanical strength of Nitronic 60, making them perfect for use in corrosive or high-stress environments.
