High-Quality Metric Thread Repair Inserts
These metric thread repair inserts are designed to restore threads to their original strength and size. Unlike traditional coil inserts, TIME-SERT® uses a solid bushing design. Therefore, this creates a more secure and vibration-resistant repair that will not loosen over time.
Suitable for a Wide Range of Applications
Our time sert metric inserts are suitable for use across a wide range of applications, including engine components, machinery, and general repairs. In addition, they are ideal for restoring damaged threads in aluminium and other softer materials. This ensures a reliable and professional finish every time.
Includes Copper Thread Insert Options
In addition to standard inserts, this category also includes metric copper thread inserts for specific applications. As a result, these inserts provide added flexibility where heat resistance or conductivity is required, while still delivering the same reliable performance.
Designed for Use with TIME-SERT® Kits
To achieve the best results, these inserts should be used with the correct installation tools and kits. For example, pairing them with compatible TIME-SERT® kits ensures accurate installation and long-lasting repairs.
