## Long description

The Suki tapping screw, measuring 4.2x16mm, is a high-quality fastener engineered for reliable connections in metal and plastic applications. Manufactured from durable A2 stainless steel and adhering to the DIN 7981C standard, this screw offers exceptional resistance to environmental factors, ensuring long-term stability in various assembly projects. The inclusion of a PH2 drive head allows for efficient installation using standard power or manual screwdrivers.
Advantages
The primary benefit of this fastener is its superior corrosion resistance, provided by the high-grade A2 stainless steel composition. This material choice makes the screw ideal for environments where moisture or temperature fluctuations might otherwise compromise standard fasteners. Furthermore, the precision-engineered thread design ensures a secure grip, while the standardized PH2 drive facilitates quick and easy installation, reducing the risk of cam-out during the fastening process.
Suitable for
Securing metal sheets to metal frames
Attaching plastic components to metal surfaces
Outdoor installations exposed to moderate weather conditions
General maintenance and repair tasks requiring corrosion-resistant hardware
This screw may not be suitable for heavy-duty structural load-bearing applications where high-tensile bolts are required. Additionally, it is not recommended for use in highly acidic or marine environments where A4 grade stainless steel would be necessary to prevent pitting or surface degradation.
Key specifications
Dimensions: 4.2 mm diameter by 16 mm length
Material: A2 Stainless Steel
Drive type: PH2
Standard: DIN 7981C
Quantity: 10 pieces per pack
To use these tapping screws, first ensure that the material thickness is appropriate for the 16mm length. It is recommended to pre-drill a pilot hole if the base material is particularly hard or thick to prevent the screw from snapping or damaging the surface. Align the component to be attached, insert the screw into the PH2 drive bit, and drive it in at a steady speed until the head is flush with the surface.
What to consider before purchase
Verify that the 4.2mm diameter is compatible with your existing holes or material thickness
Ensure the PH2 screwdriver bit is in good condition to prevent stripping the screw head
Confirm that A2 stainless steel meets the chemical resistance requirements of your specific environment
For optimal results, avoid over-tightening the screws, as this can strip the threads in the base material. Always use a manual screwdriver or a power drill with a torque limiter to maintain control during the final stages of installation.
