Countersunk Sockets - Zinc Plated

When placed into a conical cut hole, the countersunk head will sit flush with or below the surface of the surrounding material, improving the finish of the product and removing any potential trip / catch hazard.

Manufactured to DIN 7991 standards.

Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrates surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.
