Stainless Steel Triangle Socket Security Screw M2–M4 A2-70 304 Tamper-Resistant Pan & Countersunk Head

Stainless Steel Triangle Socket Security Screw M2–M4 — A2-70 304 Tamper-Resistant Pan & Countersunk Head

A2-70 304 stainless steel triangle socket security screws use a 3-point triangular drive recess that is incompatible with standard Phillips, flat, Torx, or hex drivers — providing effective tamper resistance against unauthorised access to electronics enclosures, kiosks, vending machines, and public equipment. Available in pan head and countersunk head styles in M2–M4 for miniature and small electronics applications.

Key Specifications

Why Choose Triangle Socket Security Screws?

• Tamper-resistant triangle drive — 3-point triangular recess cannot be driven by standard Phillips, flat, Torx, hex, or Pozidriv drivers; requires a dedicated triangle bit
• Effective deterrent — prevents casual and opportunistic tampering; suitable for public-facing equipment, kiosks, and consumer electronics
• A2-70 304 stainless — corrosion-resistant for indoor and outdoor applications; superior to zinc-plated carbon steel security screws
• Pan & countersunk options — pan head for standard mounting; countersunk for flush-fit tamper-resistant applications
• M2–M4 miniature range — covers the full range of electronics enclosure and consumer device fastening

Frequently Asked Questions

Q: What driver bit do I need for triangle socket screws?

A: You need a dedicated triangle (3-point / Y-type) driver bit. These are not included with the screws and must be purchased separately. Standard Phillips, Torx, hex, or flat drivers will not work and may damage the recess.

Q: How tamper-resistant are triangle socket screws?

A: Triangle socket screws provide Level 2 tamper resistance — effective against casual and opportunistic tampering by members of the public who do not carry specialised tools. They are not suitable for high-security applications where a determined attacker with access to specialist tools is expected. For higher security, consider one-way screws or breakaway head screws.

Q: Can triangle socket screws be removed once installed?

A: Yes, with the correct triangle driver bit. The tamper resistance comes from the rarity of the driver, not from a one-way mechanism. Authorised maintenance personnel with the correct bit can remove and reinstall these screws normally.
