Due to the recent Covid-19 outbreak, our trade counter is currently closed for customers. Collection is available on orders with instructions for collections once orders are placed.Courier deliveries are currently operating as normal with some delays in a small select number of locations.
We have made arrangements with suppliers to send items direct on a next day service on items that have a 3 day availability and are not on our shelves. These charges are set by our manufacturers and will depend on items ordered and delivery postcode, but should help with clearing backlogs and ensuring deliveries are received quickly if required.
This information may change at any time.
Cup point socket set screws manufactured to DIN916 standards in a bright zinc plated finish.
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.
