Self-Drilling Sharp Tip – No Pre-Drilling, Save Time & Effort
Built-in sharp self-drilling serrated tip penetrates drywall/plasterboard directly – no pre-drilling or hammering needed, completing drilling and installation in one step with an electric driver. Ideal for large-area or overhead work, reducing tool changes and steps. Countersunk cross (or flange) design ensures flush surface or larger load distribution, neat and surface-friendly – one person can finish batch fixing quickly.
Foldable Metal Expansion Wings – Large Bearing Area in Hollow Walls
Self-tightening foldable metal wings automatically expand into a butterfly shape after passing through the wall, closely hugging the back surface with a large bearing area that evenly distributes loads across drywall or partitions – effectively preventing local crushing or tearing. Made of high-strength spring steel with excellent elasticity, the wings self-lock after expansion – even long-term mounting of bathroom hardware, cabinets, or light electrical panels stays secure without loosening or pullout.
Bright Yellow Zinc Coating – Rust-Proof, Wear-Resistant & Long-Lasting
Carbon steel substrate with high-gloss yellow zinc plating – dense and uniform coating effectively resists moisture, dust, and mild corrosion, suitable for kitchens, bathrooms, and interior partitions. Wing and thread surfaces resist wear and abrasion, maintaining elastic deployment and thread locking even after repeated use. Fatigue-tested, this anchor withstands static loads and light vibration without failure – extremely low replacement frequency, offering excellent cost-performance.

Frequently Asked Questions
Is pre-drilling required when installing these self-drilling wall anchors?
No pre-drilling or hammering is required. Equipped with an integrated sharp self-drilling serrated tip, the anchor penetrates drywall and plasterboard directly using a standard electric driver in a single step.
How do the foldable metal wings provide reliable load-bearing in hollow walls?
The high-strength spring steel wings automatically deploy into a butterfly profile behind the partition wall once inserted. This expands the load-bearing area, evenly distributes weight, and prevents localized wall damage or loosening over time.
What corrosion protection does the yellow zinc plating provide?
The high-gloss yellow zinc coating forms a dense, uniform protective layer over the carbon steel substrate, resisting moisture, dust, and mild chemical exposure, making it ideal for indoor partitions, kitchens, and bathrooms.
What custom manufacturing options are available for fasteners and anchors?
We provide comprehensive customization including special head and slot geometries, extended lengths and diameters, custom surface plating colors, specialized packaging, and pre-assembled component integration.
How does your factory ensure product quality and consistency?
Quality is managed through raw material source locking, complete furnace batch traceability, optical automated sorting, real-time salt spray corrosion testing, and full compliance declarations to international standards.
Do you offer free samples and technical support?
Yes, we offer free sample fabrication and mechanical testing, alongside technical services such as on-site failure analysis, fastener selection calculations, and BOM optimization.
