Setup, Compatibility & Care
To install these screws, align the threaded end with your pre-tapped M3 hole and use a compatible hex key (Allen wrench) to tighten them until the head sits flush. Ensure the mating surface is clean and free of debris to achieve a secure hold. While the material is resistant to corrosion, it is recommended to keep the screws in a dry storage environment to maintain the silver-tone finish. Avoid over-tightening with power tools, as this can potentially damage the hex socket or the threading of the host component.
