No. Aluminum alloy is non-magnetic, making these screws safe for use in electronics and sensitive equipment where magnetic interference is a concern.
The anodized finish is integrated into the surface of the aluminum, providing good resistance to chipping and fading under normal use conditions. Avoid prolonged exposure to harsh chemicals or abrasive surfaces.
Yes. Aluminum alloy offers good corrosion resistance, making these screws generally suitable for outdoor and moisture-exposed environments. However, they are not recommended for highly corrosive or saltwater environments without additional protection.
The manufacturing tolerance is ±0.3 mm. This is standard for this type of fastener and ensures compatibility with most M3 and M4 threaded holes.
Yes. These thumb screws are commonly used for securing computer case side panels, hard drives, optical drives, graphics cards, sound cards, and network cards — anywhere tool-free access is convenient.
