M12 x 40mm Pin Torx Button Head Screw (T55) – A2 Stainless Steel
The M12 x 40mm Security Pin Torx Button Head Screw combines a M12 machine thread with a Security T55 drive and a button head. Its centre pin restricts engagement by an ordinary Torx tool while allowing servicing with the correct security bit.
What Are Pin Torx Button Head Screws?
The button head sits above the mounting surface with a rounded profile and a recessed centre-pin Torx drive. The M12 x 40mm screw must be matched to the female thread and driven with a Security T55 security bit. At Level 1 entry-level security it helps discourage casual tampering and opportunistic misuse; authorised removal remains possible.
Common Applications
- Electrical enclosures: Fix covers to suitably threaded housings where a standard Torx driver should not operate the fastener.
- Outdoor furniture: Attach serviceable brackets and fittings on furniture exposed to public access.
- Machinery guarding: Fasten removable protective panels where maintenance teams can use the matching security driver.
- Transport fittings: Secure suitable interior brackets and covers that may require periodic removal.
