Our Engineered Solutions
Structural Security Design
We engineer one-way drive screws that prevent reverse removal, custom Torx pins, and breakaway heads designed exclusively for permanent meter sealing and anti-loosening.
Material & Surface Engineering
Utilizing Stainless Steel (304 / 316) for superior corrosion resistance, and Carbon Steel with advanced coatings like Zinc Plating, Dacromet, and Black Oxide for long-term outdoor exposure.
Manufacturing Precision
Maintaining tight ±0.01mm tolerance control ensures smooth thread engagement for automated meter assembly and perfectly stable quality across large batches.
Meter-Specific Customization
Offering custom head markings (such as utility logos or serial numbers) for asset tracking, along with specific dimensional modifications to fit your exact meter housing.

FAQ
Tamper-proof screws such as one-way screws, security Torx, or breakaway screws are specifically designed to secure meters.
Generally no. To ensure anti-tampering integrity, most sealing screws (like breakaway types) are designed for permanent, one-time use.
Stainless steel (304/316) or high-grade carbon steel treated with advanced anti-corrosion coatings like Dacromet.
Yes, we fully customize the head type, thread dimensions, and even engrave specific utility logos or markings.
We provide prototype samples in 7–10 days. Mass production lead times depend on your specific order volume.
