Description
Countersunk self-tapping screws cut their own thread, so a fastener can bite into the material without a separate tapping step. GoodsAxis sources this nickel-plated carbon steel version, listed in M4, M5 and M6, for distributors, contractors and other business buyers.
Why buyers choose countersunk self-tapping screws in nickel-plated steel
The data lists carbon steel with a nickel-plated surface, Grade A and a standard purpose. The product summary says the screws suit standard industrial fastening. The listing title also calls them hardened. In general, nickel plating gives carbon steel a bright finish and some protection against rust.
The photo shows screws in gold-tone, black and silver colours, each with a sharp threaded tip. One silver screw lies on its side and shows a hex socket in a flat head. However, the specifications list a round head, while the title names hexagon flat heads. In addition, the data names nickel plating but not the other colours. Therefore, please confirm the head shape and finish you need before you order.

How to specify your screw order
We do not publish prices, because they depend on quantity, specification and destination. To get a quote, add the screws to your inquiry list or request a free quote.

After that, we reply by email within 12–24 hours with pricing and lead time for your exact order.
For a wider checklist, read our guide on how to specify fasteners for a first order from a Chinese factory. GoodsAxis is a sourcing partner, not a factory, and we use vetted China-based manufacturers.
A self-tapping screw forms or cuts a thread as it goes in, and some materials still need a pilot hole. For general background, see this overview of self-tapping screws.
