FAQs

How many pieces are in the kit?
50 pieces total (anchors and matching self-tapping screws).
What sizes are included?
Assorted M6 × 30 mm and M8 × 40 mm screws with matched expansion anchors.
What materials are the screws and anchors?
Q235 carbon steel screws with colored yellow zinc plating; plastic expansion anchors.
What type of screw drive is used?
Cross-tip (Phillips) for quick, reliable seating.
Are these suitable for drywall?
Yes—anchors are engineered for gypsum board and provide strong holding power when properly installed.
Can I use them in masonry?
Yes—pre-drill with a masonry bit to the anchor size. For heavy loads in masonry, consider dedicated masonry anchors.
Do I need a pilot hole in drywall?
Yes—drill to the anchor’s nominal hole size, insert anchor flush, then drive the screw.
What tools do I need?
Drill/driver with Phillips bit, drill bit matched to the anchor, level, pencil, and tape measure.
How much weight can these hold?
Holding strength depends on wall type, anchor size, and installation quality. For heavy items, mount into studs or use heavy-duty anchors/brackets.
Will yellow zinc plating prevent rust?
Yellow zinc provides corrosion resistance for indoor use. For high-humidity or exterior applications, use stainless or specialized anchors.
Can I reuse anchors?
Anchors are generally single-use; for the most reliable hold, use new anchors when relocating hardware.
What’s the difference between M6 and M8 in this kit?
M8 is larger and typically supports more load than M6, given proper installation and substrate.
Are the screws truly self-tapping?
Yes—threads cut into the anchor and bite into the base material as you drive.
Do these work with floating shelves?
Yes for light/medium shelves; for heavy shelves, mount into studs or use heavy-duty fasteners per shelf manufacturer.
Can I use these for curtain rods?
Yes—select the M6 or M8 hardware based on bracket holes and expected load.
What pilot size should I drill?
Match your bit to the anchor’s shank/label. The anchor should press-fit snugly before driving the screw.
What is Q235 carbon steel?
A common structural carbon steel grade that balances strength, ductility, and cost—ideal for general hardware.
Is this kit suitable for wood studs?
If fastening into a stud, screws can be driven directly without the plastic anchor. Predrill as needed to avoid splitting.
Are there any hazardous chemicals?
No high-concern chemicals are declared for this kit.
Do you offer larger packs?
Yes—contact Conversions Tech for bulk or contractor-grade quantities.
Can I get stainless screws instead?
We can supply stainless assortments on request for high-humidity or coastal environments.
