Why are threaded inserts brass?
Threaded inserts are often made of brass for the following reasons:
Corrosion Resistance: Brass has good corrosion resistance, making it suitable for applications where moisture or chemicals may be present. This property helps extend the life of the insert and maintain the integrity of the threaded connection.
Machinability: Brass is relatively easy to machine, allowing for precise manufacturing of threaded inserts. This makes it easier to produce inserts with precise dimensions and threads.
Strength and Durability: While brass is not as strong as some steel inserts, it offers a good balance between strength and ductility. Brass can handle moderate loads and, being a softer material, is less likely to strip the threads.
Non-magnetic: Brass is non-magnetic, which is an advantage in certain applications, such as electronic devices or sensitive equipment, where magnetic interference needs to be concerned.
Cost Effective: Brass is generally more affordable than some other high-strength materials, making it an affordable choice for many applications.
Thermal Conductivity: Brass has good thermal conductivity, which is very useful in applications where heat dissipation is important.
Overall, brass is a popular choice for threaded inserts across a variety of industries due to its combination of useful performance characteristics and cost-effectiveness.
A properly designed bolted joint must meet the following criteria:
The head of the bolt, or washer if one is used, should always seat against both theplastic host and the Compression Limiter under load. This will prevent deterioration ofthe bolted joint resulting from diminished clamping load due to plastic creep.
The rated proof load of the Compression Limiter should be equal to or greater thanthe proof load of the bolt to assure that the Compression Limiter will not yield prior tothe bolt under excessive clamping loads.
The mating component that the Compression Limiter seats against should be strongenough to withstand the localized compressive stresses generated by the clampingforce.
The clearance between the maximum bolt diameter and the minimum installed insidediameter of the Compression Limiter should be sufficient to compensate for expectedassembly tolerances.
