Surface treatments, such as zinc plating or galvanization, provide a barrier against corrosion. These coatings sacrifice themselves to protect the underlying steel from oxidation. The effectiveness of these coatings depends on their thickness and application quality. Damage to the coating, such as scratches, can compromise its protective function. Example: Zinc-plated bolts, commonly available, offer a degree of corrosion resistance suitable for many indoor installations, but may degrade over time in high-humidity environments or with prolonged exposure to cleaning agents.
-
Compatibility with Cabinet Materials
The chemical properties of the fastener material must be compatible with the cabinet material to prevent galvanic corrosion. Dissimilar metals in contact, especially in the presence of an electrolyte (such as moisture), can create a galvanic cell, accelerating corrosion of the more anodic metal. This is especially relevant when mounting a microwave to cabinets constructed of aluminum or other metals. Example: Using steel bolts with aluminum cabinets requires an insulating barrier, such as nylon washers, to prevent galvanic corrosion.
-
Impact on Installation Torque
The material composition affects the optimal torque for tightening the fasteners. Over-tightening can strip threads or fracture the bolt, while under-tightening can lead to loosening over time. Harder materials, such as high-grade steel, can withstand higher torque values. The chosen fastener material must be considered when setting the torque wrench. Example: High-strength alloy bolts require precise torque settings to achieve optimal clamping force without exceeding their yield strength.
The correlation between material choices and the reliable performance of microwave mounting bolts underscores the need for informed selection.
