M2 Triangle Head Security Anti Theft Metal Screw ASTM A193 A914 B8 B8M B8T ASTM A453 GR660 A286 18-8 Plain

This miniature triangle head security screw is designed for small‑scale yet critical anti‑tamper applications. The M2 diameter makes it suitable for compact electronic devices and precision instruments. The material range is exceptionally broad: ASTM A193 Grade B8 (304), B8M (316), B8T (321), ASTM A453 Grade 660 (A286 superalloy), and standard 18‑8 stainless steel. All materials meet rigorous high‑temperature or high‑corrosion standards. The plain finish relies on the alloy’s natural passive layer. The triangle drive requires a dedicated key, preventing unauthorised removal. These screws are often used where space is limited but security is paramount.

• Smart meters and IoT sensors – prevents tampering with calibration.
• Miniature access panels on laboratory equipment.
• High‑temperature furnace controls – A286 retains strength at 650°C.
• Chemical analyser housings – B8M resists aggressive reagents.
• Small outdoor enclosures for telecommunications.

• Ultra‑compact M2 size – ideal for miniaturised security fastening.
• High‑temperature materials – A286 works up to 650°C without losing tamper resistance.
• ASTM certified alloys – guaranteed traceability for critical industries.
• Triangle drive security – no standard bit can engage.
• Plain finish – no coating to chip, retains full alloy performance.
