Extended Product Information
FAQs
What material are these screws made of?
The base material is not specified, but they are nickel plated for enhanced corrosion resistance.
What is the head type and drive type?
They have a raised countersunk (CSK) head with a slotted drive.
How many screws are included in a package?
Each polybag contains 100 screws.
What is the primary benefit of the nickel plating?
The nickel plating provides excellent resistance to corrosion, helping to prevent rust and extend the product's lifespan.
Can these be used outdoors?
Yes, the nickel plating offers good corrosion resistance, making them suitable for many outdoor applications, though prolonged exposure to harsh elements might eventually cause wear.
What size screwdriver do I need?
You will need a flathead (slotted) screwdriver. The exact size depends on the specific screw size, but ensure it fits snugly into the slot without wobbling.
Are these screws magnetic?
Nickel-plated screws are typically magnetic, as the base metal is often steel. However, the plating itself does not significantly alter magnetism.
Troubleshooting
Screw head strips during installation
Ensure you are using the correct size flathead screwdriver. Apply firm, downward pressure to keep the screwdriver engaged in the slot and avoid over-tightening.
Screw does not tighten properly
Verify that the mating hole or nut is correctly tapped and compatible with M-size machine screws. Check for thread damage on both the screw and the receiving component.
Visible rust or corrosion
While nickel-plated, extreme conditions can lead to corrosion. Clean the affected area gently with a soft cloth. For future applications in harsh environments, consider specialized coatings or stainless steel fasteners.
Pros and Cons
Pros
- Excellent corrosion resistance due to nickel plating.
- Suitable for diverse materials and project requirements.
- Easy to install with standard flathead tools.
- Durable build quality for long-lasting use.
- Conveniently packaged in quantities of 100.
Cons
- Slotted head can be prone to cam-out if excessive force is applied.
- May not be suitable for high-torque applications where Phillips or Torx heads are preferred.
- Nickel plating can be scratched or chipped under extreme conditions.
- Requires specific flathead screwdriver size for optimal use.
Setup, Compatibility & Care
Setup:
- Select the appropriate pilot hole size for your material.
- Use a flathead screwdriver that fits snugly into the screw's slot.
- Drive the screw carefully, applying steady pressure, until the head is flush with the surface.
Compatibility:
These machine screws are designed for use with corresponding nuts or tapped holes. They are compatible with a wide range of materials including wood, plastic, and thin metals where a machine screw thread is appropriate.
Care:
To maintain the corrosion resistance of the nickel plating, avoid abrasive cleaners or harsh chemicals. Wipe with a dry or slightly damp cloth if dust accumulates. For long-term storage, keep them in their original polybag in a dry environment.
