DIN 965 4,8 zinc-nickel black Countersunk head screw with Phillips head PH

DIN 965 screws are screws that consist of a countersunk head with a slot and a full threaded rod.

The countersunk head means that when tightened, the screw is almost flush with the surface into which it is fixed. This helps to ensure an aesthetic appearance of the connection.

The Phillips head spline is a type of spline that is quite convenient to use and ensures reliable tightening of the screw.

Application: furniture production, automotive industry, electronics, construction, where a compact and aesthetic connection is required.

Material of manufacture: steel, strength class 4.8.

Coating: black zinc-nickel. Zinc-nickel coating is an innovative anti-corrosion solution for fasteners that combines high protective ability, mechanical strength and environmental safety.

The key advantages of zinc-nickel coating are:

• Excellent corrosion resistance - more than three times higher than that of ordinary zinc;
• Low risk of hydrogen embrittlement;
• Compatibility with aluminum - does not form galvanic vapors and does not cause corrosion in combination with aluminum parts;
• Increased heat resistance - retains protective properties at changing temperatures and during prolonged operation in high-temperature conditions;
• Mechanical strength - harder than pure zinc, has better resistance to scratches and wear;
• Environmental friendliness - less formation of oxidation products, thus lower zinc emissions into the environment throughout the product's life cycle.
• Aesthetics and invisibility - the coating has a deep black color, which makes it hardly noticeable.
