Welcome to our store!

These black zinc-plated screws are designed for reliable and precise fastening applications. Each screw features a standard zinc-plated base with a decorative black coating applied, enhancing the overall tightness of the product. The black coating provides slightly increased protection against corrosion, and its thin application ensures it does not interfere with the threads. The coating is solvent-based, chemical-resistant, and meets RoHS2 standards for safety. There is no build-up in the threads or the recess of the heads, making them convenient to use without obstruction. Please note that due to the thin application, the coating may scratch slightly with heavy friction.
