M3 x 16 mm Machine Screw Black Oxide

These M3 x 16 mm machine screws with a black oxide finish are precision-engineered fasteners designed to provide reliable and durable fixings for your electronic assemblies. Their compact dimensions make them ideally suited for securing printed circuit boards, mounting small components, or attaching panels within enclosures where a neat, professional finish is required. The black oxide coating not only offers a subtle, non-reflective appearance but also enhances resistance to corrosion, ensuring long-term performance even in environments where moisture or handling may be a concern.

Each screw is manufactured with a precisely formed M3 thread and a length of 16 mm, allowing for secure engagement with standard nuts or threaded inserts. The thread pitch is carefully controlled to deliver consistent, smooth fastening without damaging delicate materials. The black oxide finish is applied through a controlled chemical process that provides a protective layer while maintaining the dimensional accuracy of the threads. This treatment also reduces glare, which can be beneficial in optical or display applications. Whether you are assembling audio equipment, prototyping circuits, or performing maintenance on electronic devices, these machine screws offer a dependable solution that combines strength, corrosion resistance, and a clean, understated aesthetic.
