BaerFix Thread Inserts with cutting holes M 8 x 1.25 - 9 mm - 10 pcs.
BaerFix Thread Inserts with cutting holes M 8 x 1.25 - 9 mm - 10 pcs.
BaerFix® thread inserts with three tapping holes are self-tapping and guarantee a permanent fixed thread connection in your workpiece and are extremely easy to handle. Simply screw them into the hole - you cut the holding thread yourself.
If your thread is worn or torn out, a stable material connection is no longer possible. This is where the BaerFix® self-tapping thread insert comes in. With our self-tapping thread inserts you can repair your broken internal thread or strengthen an existing thread. If there are damaged threads in your components, this does not have to be a waste. Simply insert a threaded bush with the same internal thread into the component, so that your thread is not only repaired, but can also be loaded at the same time with higher pull-out strength and is also more wear-resistant.
With BaerFix® thread inserts you need fewer connecting parts, reduce the screw dimensions to be used, save material and space - and all this with low weight and high requirements. For many products, saving weight is an important factor.
The BaerFix® self-tapping thread inserts with cutting holes are ideal when you want to create a strong connection for materials that are difficult to machine. These inserts have a thicker wall and can therefore absorb more force, which is also distributed over three cutting holes. They are also the right choice if you do not need a screw locking effect. If a clamping effect is desired, we recommend our self-tapping thread inserts with cutting slots.

Attributes
- Thread repair damaged or worn threads
- Scrap recovery
- Thread armoring of materials with low shear strength such as aluminium and magnesium alloys, wood, PVC, etc
- For example, in an application in light metal, a pull-out strength can be achieved that is higher than the yield strength of an 8.8 screw.
- Cutting the holding thread itself during screwing in
- high compression with the holding material
- very high pull-out strength
- minimises space and weight
- high corrosion resistance
- easy to use
- Areas of application in the entire metal and plastics processing industry
