Product Applications
Public Facility Security: Used in outdoor guardrails, traffic signs, billboards, municipal equipment, park facilities, and similar applications—the tamper‑proof design prevents malicious screw removal, ensuring the safety and integrity of public infrastructure.
Equipment and Cabinet Protection: Fastening of electrical appliance housings, public enclosures, communication equipment, and security device casings, preventing unauthorized disassembly or alteration by unauthorized personnel, thereby enhancing equipment safety and stability.
Outdoor and Humid Environments: Suitable for outdoor furniture, garden structures, landscaping equipment, marine components, and more—the corrosion resistance of 304 stainless steel effectively withstands rain and moisture, preventing rust‑related failure.
Light Metal and Wood Connections: Fastening of sheet metal parts, aluminum profiles, wood boards, and plastic components—the self‑tapping thread requires no pre‑tapping for easy installation, while the round head design also meets various aesthetic requirements.
Product Features
Tamper‑Resistant S‑Type Drive: The one‑way S‑type security slot design allows standard tools to tighten but not loosen the screw, effectively preventing unauthorized removal and tampering with strong security protection.
304 Stainless Steel for Corrosion Resistance and Durability: Made from A2‑grade stainless steel, it offers excellent rust and corrosion resistance, suitable for humid, outdoor, and other harsh environments, with stable strength and a long service life.
Round Head for Strong Adaptability: The arched pan‑head profile does not scratch surfaces, and its large bearing area prevents deformation of panels, making it suitable for surface mounting on various materials.
Self‑Tapping Thread for Efficient Installation: The #10‑16 coarse self‑tapping thread eliminates the need for pre‑tapping—it can form its own mating threads directly, enabling quick and convenient installation.
