Custom Security Screws & Tamper-Resistant Fasteners
Engineered for infrastructure protection. We provide 0.05mm precision tamper-resistant screws with custom drive designs and 10-day rapid prototyping.
Product Introduction
Industry pain points and background
Meters, enclosures, rail infrastructure and public equipment are constant targets for tampering and theft. Standard screws can be removed with ordinary tools, leaving critical assets exposed and warranties disputed. Guanbiao's security screws use custom drive geometries that standard bits cannot turn, protecting your equipment throughout its service life.
