K0399 Reinforced Thread Inserts In Steel Size M4-M24

List view Grid view

Material, surface finish:
Threaded insert in steel or stainless steel, passivated Note:
Reinforced Threaded Inserts allow threaded holes which have been damaged, torn out or jammed to be used again or repaired. This makes it possible to recover scrap and rejects of expensive products. Reinforced Threaded Inserts are suitable for use in various materials, including light metals and casting.
Inserts with internal threads larger than M6 are supplied with four locking pins instead of two. Permissible deviations:
the medium tolerance class applies to the threads listed, i.e. 6H for nut threads and 6g for bolt threads. Other dimensions ±0.25 mm. With Reinforced Threaded Inserts we also offer a version with a stronger cross-section for use in applications with greater stress. Technical Information see operating instructions for threaded inserts. Benefits:
- Quick and easy installation.
- The insert is fixed with pins in order to prevent torsion due to twisting or vibrations.
- No other special tools are needed besides the assembly tool.
