Feature
|
Detailed Specifications
|
|
Core Material
|
Premium 304 stainless steel (18% chromium, 8% nickel) — forms a self-healing passive oxide layer for superior corrosion resistance. Compliant with ASTM A270 and ISO 3506 standards.
|
|
Tamper-Resistant Design
|
Torx (Tx) drive with center pin (Torx Plus Security/Torx Tamper-Proof) — requires specialized tools for installation/removal, preventing theft, vandalism, or unauthorized adjustments.
|
|
Head Style
|
Rounded (pan) head — low-profile, smooth finish for aesthetic appeal and snag-free surfaces. Ideal for visible applications where a clean look matters.
|
|
Self-Tapping Threads
|
Precision-cut threads (Type AB/Type C) for easy penetration into metal, wood, plastic, and composite materials. Eliminates the need for pre-drilling (in thin materials) and ensures secure, vibration-resistant engagement.
|
|
Strength & Durability
|
Tensile strength ≥ 515 MPa, yield strength ≥ 205 MPa. Operating temperature range: -270℃ to 870℃ — withstands extreme cold, heat, and thermal cycling.
|
|
Finish
|
Natural 304 stainless steel (brushed or polished) — resists discoloration, rust, and tarnish. No additional coatings required (optional passivation for enhanced corrosion resistance).
|
|
Available Sizes
|
Diameters: #2 to #14 (metric: M3 to M8); lengths: 6mm to 50mm. Compatible with standard Torx security tools (Tx8 to Tx40).

Core Product Advantages
- Tamper-Proof Security
The Torx security drive with center pin blocks access with standard screwdrivers/wrenches—critical for securing public equipment, data centers, medical devices, and high-value assets. Reduces vandalism and theft risks by 90% compared to standard screws.
- 304 Stainless Steel Corrosion Resistance
Withstands saltwater, humidity, chemicals, and outdoor exposure. Salt spray test certified for 1000+ hours without visible rust—outperforming carbon steel and even lower-grade stainless steel. Perfect for coastal areas, bathrooms, kitchens, and industrial environments.
- Self-Tapping Convenience
Threads cut their own holes during installation, saving time and eliminating pre-drilling (in materials up to 3mm thick). Ensures tight, secure fits in diverse substrates (metal sheets, plywood, PVC, fiberglass) — ideal for DIY projects and professional assembly lines.
- Rounded Head Aesthetics & Functionality
Smooth, low-profile rounded head creates a clean, finished look for visible applications (furniture, signage, architectural trim). Eliminates sharp edges, reducing snagging on clothing, cables, or hands.
- Long-Term Durability & Reliability
Resists vibration, temperature extremes, and mechanical wear—maintains structural integrity for 10+ years in indoor/outdoor use. No loosening over time, reducing maintenance and replacement costs.
Key Application Scenarios
Our 304 stainless steel tamper resistant Torx rounded head self tapping screws are trusted across industries for their security, durability, and versatility:
1. Industrial & Commercial Equipment
- Securing control panels, electrical enclosures, and server racks (prevents unauthorized access to sensitive components).
- Mounting machinery guards, conveyor systems, and production line parts (corrosion resistance for factory environments).
- Fastening outdoor kiosks, vending machines, and ATM components (tamper-proof against theft/vandalism).
2. Architectural & Construction
- Installing exterior fixtures: handrails, lighting, signage, and window frames (304 stainless steel resists weathering).
- Securing decorative trim, cabinetry, and furniture in commercial buildings (rounded head for aesthetic appeal).
- Fastening coastal structures: docks, boat lifts, and outdoor furniture (saltwater corrosion resistance).
3. Residential & DIY Projects
- Mounting bathroom/kitchen hardware (towel racks, toilet paper holders) — humidity-resistant and tamper-proof.
- Installing outdoor lighting, fence panels, and decking (withstands rain, snow, and UV exposure).
- Securing shelving, mirrors, and wall art (clean rounded head complements home decor).
4. Medical & Food Industry
- Fastening medical equipment housings and laboratory fixtures (304 stainless steel is non-toxic and easy to sanitize).
- Mounting food processing machinery components (corrosion resistance for washdown environments, tamper-proof for safety).
5. Transportation & Marine
- Securing RV/camper fixtures, boat hardware, and automotive interior components (vibration-resistant and corrosion-proof).
- Fastening trailer parts and outdoor vehicle accessories (withstands road salt and harsh weather).
