Self-tapping threaded inserts for making high-strength, wear-free, vibration resistant screw connections in materials with low shear strength such as aluminium and aluminium alloys, brass, bronze, cast iron, duro and thermoplastics. The threaded inserts are tapered at the bottom and have a cutting slot. By screwing in they cut their own threads inside a receiver hole. This guarantees a completely secure and firm anchoring in the host material. Internal thread D1 acc. to ISO 6H. The threaded inserts with cutting slot spring slightly inwards in the slot region in some materials. This results in a screw locking effect. If this is not desired, we recommend the threaded inserts with a cutting bore.

High quality self-tapping ensat thread inserts. Made of ASIS 304 stainless steel Long version with three cutting holes, Ensat 308 standard Particularly designed for materials resistant to cutting and where you want to exclude any slight self-locking effect on the screw. With the same insertion torque, they exert a higher and better distributed cutting force compared to Ensat 302 inserts, having three cutting points instead of two. Similar to Ensat 307 but longer, so can be applied in thicker materials These inserts are self-tapping and do not require pre-threading. They can be easily installed by screwing them into the appropriately sized hole using the installation tool They are usually used to enforce or repair threads in metallic materials with low shear resistance (metal alloys, aluminum, cast iron, plastic, castings, etc.). These self-threading bushes have an internal thread for the screw and an external thread with cutting slots to insert itself into the material

Keensert high-strength threaded inserts enter in pre-threaded holes and are secured via their locking keys. In High duty series they have 2 or 4 locking keys (depending from diameter) which once positioned make the insert mechanically locked against unscrewing from rotation or vibrations. Keenserts are extremely robust, have high resistance to rotation and extraction, a very precise thread and are easy to install and remove. They are widely used in sectors such as mechanics or precision engineering, aeronautics and aerospace on light alloys, steel or cast iron. They can also be used in damaged threads in expensive components. The Keensert inserts are supplied with the locking keys already positioned inside the grooves. The pre-positioned keys ensure that by screwing the insert it automatically positions itself at the correct installation depth. Keenserts are installed using special Keenest installation tool.
