Self-Tapping Screws
Self-tapping screws form their own thread as they are driven into material, so no pre-tapped hole is needed. We supply pan head cross (Phillips) self-tapping screws and thin head screws as current supply lines, in 304 stainless steel, nickel plated and black oxide finishes.

About this category
A self-tapping screw cuts or forms its mating thread in the substrate — typically sheet metal, wood, or plastic — which makes assembly fast and suited to high-volume production lines. The tapering thread and hardened surface do the work that a separate nut and tapped hole would otherwise do.
Head choice changes both the finish look and the load distribution. Pan heads sit above the surface with a wide bearing area; thin (low-profile) heads keep the fastener discreet where clearance or appearance matters. Cross recess (Phillips) drive is the most common for small sizes and works with standard electric drivers.
Typical applications
- Sheet metal and bracket assembly
- Electronics enclosures and plastic housings
- Wood and composite joinery for hardware products
- Repair and maintenance work where pre-tapped holes are impractical

Self-Tapping Screws — common questions
Which finish should I choose for self-tapping screws?
304 stainless offers the best corrosion resistance without plating; nickel plated gives a bright decorative surface on carbon steel; black oxide finish suits internal assemblies where appearance is secondary. Availability of a specific combination depends on specification — ask us with your sizes.
Can you supply sizes that are not listed on the product pages?
The product pages show our current families. Size availability depends on specification — send us the diameter, length and finish you need and we will confirm sourcing options with a quotation.
What information helps you quote faster?
Head type, drive, material or finish, diameter × length, approximate quantity and destination country. A photo or drawing of the screw also works — you can attach one in the RFQ form.
