BaerFix Thread Inserts have a conical lead with cutting slots on the metric external thread. They are designed to cut their own threads as they are being driven into a drilled hole (self-tapping). This provides a secure and high-strength anchor. BaerFix for creation of wear-free, vibration resistant screw joints with high loading capacity in materials with low shearing strength.

Large effective shearing surface
The BaerFix Thread Insert has a large effective surface, so ensuring a higher degree of pull-out strength, i.e. an M 5 is often sufficient instead of a cut M 6 thread.

Flange Cover
In a workpiece made of a light alloy, the BaerFix Insert achieves almost maximum pull-out strength with only 30 % flange cover.

Pull-out Strength
A BaerFix Thread Insert is capable of withstanding high loads. When used in light alloys, for example, a degree of pull-out strength is achieved which far exceeds the yield strength of a screw 8.8.

Minimize Weight & Space
Weight saving is unmatched - an important design feature for many products, particularly airborne equipment. Space saving is maximised, permitting the use of standard boss configurations with oversize boss requirements - as is necessary to accommodate solid bushings. A boss radius equal to the norminal bolt size is adequate for most load conditions.

Corrosion Resistance
The superior corrosion resistant characteristics of BaerFix inserts assure their adaptability to most materials and usual enviromental conditions.

Minimize Total Cost
Overall production cost savings may be realised by using a less expensive material and still maintain the required thread strength with BaerCoil inserts. Costs savings apply in many directions - lower insert cost, lower installation costs and smaller bosses all produce savings.

Quality and Reliability
Stringent Quality Control is rigorously enforced in all phases of manufacturing.
