Product Information
Full details
This guide is for professionals and home users needing durable fasteners for various projects. The key benefit is their strength and corrosion resistance for reliable connections. A caveat is their specific application as self-tapping screws, requiring pilot holes for softer materials. This pack contains 30 silver, steel, zinc-plated self-tapping screws with a Phillips No2 PH2 head and domed head, measuring 3.5mm in width and 12mm in total length.

FAQs
What material are these screws made from?
These screws are manufactured from steel for strength and durability.
What does 'self-tapping' mean?
Self-tapping screws are designed to cut their own threads into materials like metal and plastic as they are driven, simplifying assembly by eliminating the need to pre-tap threads.
What type of screwdriver do I need?
You will need a Phillips No2 (PH2) screwdriver or a compatible bit for your power drill.
How do I prevent the screw head from stripping?
Use the correct size Phillips No2 bit, ensure it's fully seated in the screw head, and apply firm, consistent pressure while driving. Avoid over-tightening.
Can these screws be used outdoors?
Yes, the zinc-plated finish provides rust and corrosion resistance, making them suitable for many outdoor applications. However, prolonged exposure to harsh elements may eventually affect the plating.
What are the exact dimensions of the screws?
These screws have a width of 3.5mm and a total length of 12mm.
How many screws are in a pack?
Each pack contains 30 self-tapping screws.
Troubleshooting
Screw head strips during installation
Ensure you are using the correct size Phillips No2 driver bit and that it is fully seated in the screw head. Apply firm, steady pressure and avoid excessive torque. If the head is already damaged, you may need to use screw extractors.
Screw does not tap effectively into material
Verify that the material is suitable for self-tapping screws. If the material is harder than anticipated, drill a properly sized pilot hole before attempting to drive the screw. Ensure you are using adequate driving force.
Screw breaks during installation
This often indicates over-tightening or a lack of a pilot hole in a material that requires one. If a portion of the screw remains embedded, specialized screw extractors may be needed.
Rust or corrosion appears on the screw
While zinc-plated, extreme or prolonged exposure to moisture and corrosive elements can eventually wear down the plating. For such conditions, consider screws with enhanced coatings or materials.
Pros and Cons
Pros
- Strong and durable steel construction
- Resistant to rust and corrosion due to zinc plating
- Easy installation with a common Phillips drive
- Suitable for creating their own threads in various materials
- Provides a clean finish with a domed head
Cons
- Requires pre-drilled pilot holes in harder materials or for precise placement
- May not be suitable for extremely heavy-duty applications
- Specific size (3.5mm x 12mm) may not fit all project requirements
- Phillips drive can be prone to cam-out if excessive torque is applied
Setup, Compatibility & Care Instructions
Setup:
- Pilot Hole: For best results and to prevent material splitting, especially in harder metals or plastics, it is recommended to drill a pilot hole slightly smaller than the screw's minor diameter (thread root diameter).
- Driving: Use a Phillips No2 screwdriver or a compatible drill bit. Ensure the driver bit is fully engaged in the screw head to prevent stripping.
- Tightening: Drive the screw until it is snug. Avoid over-tightening, which can strip the threads in the material or damage the screw head.
Compatibility:
- These screws are designed to tap into materials such as sheet metal, aluminum, plastic, and certain types of wood (with a pilot hole).
- Compatible with standard Phillips No2 screwdrivers and power tool attachments.
Care:
- Store screws in a dry environment to maintain the integrity of the zinc plating.
- Clean any dust or debris from the screws before use, though they typically arrive clean and ready.
- The zinc plating offers corrosion resistance; however, prolonged exposure to highly corrosive environments may eventually affect the plating.
