Installation/Set-Up Challenges for Zinc Plated Fasteners

Zinc plated fasteners are commonly used in various industries due to their corrosion resistance properties. However, there are some common installation or setup challenges associated with them:

1. Hydrogen Embrittlement: During the plating process, hydrogen can be introduced into the metal, leading to hydrogen embrittlement. This can make the fasteners more susceptible to cracking or failure under high stress.

2. Thread Galling: Zinc plating can cause friction during installation, resulting in thread galling, where the threads seize and lock together. This can make it difficult to tighten or remove the fastener.

3. Mismatched Materials: When zinc plated fasteners are used with dissimilar metals, such as stainless steel or aluminum, galvanic corrosion can occur. This can weaken the fastener and the material it is attached to.

4. Over-torquing: Zinc plating can provide a lubricated surface, which may lead to over-torquing the fastener during installation. This can cause deformation or failure of the fastener.

5. Environmental Factors: Zinc plated fasteners may not be suitable for applications exposed to harsh environments or extreme temperatures, as the plating may degrade over time, reducing their effectiveness.

To mitigate these challenges, it is important to follow manufacturer recommendations for installation, use proper tools, avoid mixing materials, and consider alternative coating options based on the specific application requirements.
