FAQs
What material are these screws made of?
These screws are made from 410 stainless steel, known for its strength and corrosion resistance.
Do I need to pre-drill holes for these screws?
These are self-tapping screws, meaning they are designed to create their own threads in metal, often eliminating the need for pre-drilling. However, for very hard metals or thicker materials, pre-drilling a pilot hole might be beneficial.
What is the head type of these screws?
They feature a modified truss head, which provides a wider bearing surface compared to a standard pan head.
What size are these screws?
The size is M4.8*38mm, indicating a diameter of approximately 4.8mm and a length of 38mm.
Is a driver bit included?
Yes, a driver bit is included for your convenience.
Can I use these screws in wood?
These screws are specifically designed for metal applications. Using them in wood is not recommended as they may not function correctly and could damage the material.
How should I store these screws?
Store the screws in a cool, dry place to maintain their integrity and prevent corrosion.
Troubleshooting
Screw is difficult to drive
Ensure you are using sufficient downward pressure and the correct rotational speed. For very hard metals, consider drilling a small pilot hole. Check that the driver bit is seated correctly in the screw head.
Screw head strips out
Reduce driving pressure and ensure the driver bit is fully engaged. If stripping continues, the material may be too hard for this screw, or a pilot hole is needed. Replace the screw if significantly damaged.
Screw does not grip or threads are not forming
Verify that you are driving the screw into a suitable metal substrate. Ensure the material thickness is appropriate for the screw length. If the hole is already tapped, the screw may not be able to create new threads.
Corrosion noticed on screw
While made of 410 stainless steel, extreme conditions can still affect appearance. Clean the screw with a mild detergent and water. Ensure storage in a dry place to prevent future issues.
Pros and Cons
Pros
- Durable 410 stainless steel construction for longevity.
- Self-drilling capability speeds up installation.
- Modified truss head ensures a secure and stable hold.
- Includes a driver bit for immediate use.
- Corrosion-resistant, suitable for various conditions.
Cons
- May require significant force for harder metals.
- Not suitable for wood or soft materials without pilot holes.
- Specific size may not fit all applications.
- The included driver bit might wear out with extensive use.
Setup, Compatibility & Care
Setup:
Ensure you have a power drill or driver equipped with the included driver bit. Align the screw with the desired fastening point on the metal surface. Apply firm, steady pressure while driving the screw to allow it to tap its own threads effectively. For very hard metals or thicker gauge materials, a pilot hole may be advisable to ease installation and prevent stripping.
Compatibility:
These screws are designed for use in metal applications. They are compatible with standard drill/driver chucks that can hold the included bit. Avoid using them in wood, plastic, or brittle materials where they may not perform as intended or could cause damage.
Care:
Store screws in a dry environment to maintain their corrosion resistance. If the screws become dirty, wipe them clean with a dry or slightly damp cloth. Avoid abrasive cleaners. Regularly check any fastened components for tightness, especially in applications subject to vibration.
