Brake Pad Retention Clips: The Risk No One Considers

The retaining clip is the most overlooked part of the braking system. It's also one of the most critical—especially in the automotive aftermarket, where the variety of applications and operating requirements makes selecting the right coating essential.

Hydrogen Embrittlement: why a perfect part fails after zinc plating

A Class 12.9 bolt passes all quality controls, is installed correctly, and fails after 72 hours. There is no visible corrosion. There was no overloading. The problem occurred before assembly, during the coating process. It's called hydrogen embrittlement, and in the metalworking industry, it's one of the most underestimated failure modes.
