Security screws (also called tamper proof screws or anti-theft screws) are purpose-built fasteners that require dedicated matching tools to install and remove, effectively stopping unauthorized disassembly, vandalism and part theft. They are standard hardware for outdoor public facilities, security equipment, telecom cabinets and retail display fixtures where tamper resistance is mandatory.
YH Fastener is a professional security fastener manufacturer with nearly 30 years of production experience. We supply a full lineup of security screws and bolts in all mainstream drive styles, with stainless steel, carbon steel and brass material options. Standard metric and imperial sizes are kept in bulk stock, and full OEM/ODM custom solutions are available for industrial projects.
Main Security Screw Drive Types
We carry all common anti-tamper drive profiles to match different security levels and assembly scenarios:
The most widely used security fastener style, with a central pin inside the torx recess to block standard torx wrenches. It balances high tamper resistance and smooth installation with matching key tools. Ideal for outdoor cabinets, security enclosures and industrial equipment. Available in pan head, countersunk head, button head and hex head forms.
Features a triangular drive socket that cannot be engaged by regular screwdrivers. Medium-to-high anti-tamper level, commonly used for public facilities, electrical meters and retail display cases. Simple tool structure, cost-effective for large-volume projects.
One-way clutch design that can only be tightened, not loosened with standard tools. Maximum tamper resistance for permanent installations. Suitable for road signs, guardrails and public facilities that do not require later disassembly.
Snake eye (2-hole), tri-wing, hex socket with pin, spanner head security screws and security bolts. Custom exclusive drive profiles can be developed for clients with high-level anti-theft requirements. Matching security nuts and washers are available for complete fastening solutions.
Key Application Scenarios
1. Outdoor Public Facilities & Street Furniture
Used for bus stop shelters, road signs, guardrails, public benches and trash bins. Public areas face high vandalism and theft risks, so fasteners must block unauthorized removal.
- • Core requirements: Weather corrosion resistance, reliable tamper resistance, long service life
- • Matching product: 304 stainless steel one way security screws or torx security bolts, M6-M12 sizes, passivated finish for outdoor use
2. Security & Access Control Equipment
For access control panels, surveillance cameras, alarm systems and security door locks. Tamper-proof fasteners protect equipment from being dismantled and stolen.
- • Core requirements: Concealed flush installation, outdoor corrosion resistance, mini sizes for compact devices
- • Matching product: Countersunk stainless steel security screws, M2.5-M6 sizes, flat hidden head for a clean uniform appearance
3. Telecom & Electrical Enclosures
Outdoor telecom cabinets, power distribution boxes and electrical meters need anti-theft fastening to prevent unauthorized access and internal component theft.
- • Core requirements: Vibration resistance, weather sealing, compatible with standard panel thicknesses
- • Matching product: Flange head torx security bolts with nylon locking patch, available in zinc-plated carbon steel or stainless steel
4. Retail & Commercial Display Fixtures
For display shelves, vending machines, POS equipment and public furniture. Prevents customers from disassembling fixtures or stealing internal parts and merchandise.
- • Core requirements: Low-profile clean appearance, finish matching the fixture, cost-effective for bulk use
- • Matching product: Black oxide or zinc-plated security machine screws, M3-M5 sizes, button or pan head style
