R-TECH Steel Nuts BZP - M2.5 - Pack Of 100

These nuts are made from Grade 8 steel.

They have a bright zinc-plated, clear passivated finish.

These nuts are designed for M2.5 screws or bolts.

The bright zinc-plated, passivated finish offers good corrosion resistance, making them suitable for many general outdoor applications, but prolonged exposure to harsh elements may eventually affect the finish.

Each pack contains 100 nuts.

They are designed for M2.5 bolts. Using them with different thread sizes will not create a secure connection and could damage the threads.

Passivation is a chemical treatment that removes free iron from the surface of steel, enhancing corrosion resistance by forming a passive oxide layer.

Ensure you are using an M2.5 bolt and that both the bolt and nut threads are clean and free from damage or debris. Check for cross-threading.

Verify that the bolt or screw is the correct M2.5 size and that it is engaging properly with the nut's threads. The bolt may be stripped or too short.

This may indicate exposure to harsh chemicals or prolonged moisture. While the passivation layer offers protection, extreme conditions can affect the finish over time. For critical applications, consider alternative materials or coatings.
