Spanner Tamper-Resistant Security Screws

Security spanner machine screws are designed for applications where standard fasteners are too easy to remove. Also known as tamper-resistant spanner machine screws, these fasteners use a two-hole drive that helps deter unauthorized removal while still allowing installation and maintenance with the proper driver. Tanner offers security spanner machine screws in a range of head styles, sizes, and stainless steel options for commercial, industrial, and institutional use.

Tamper-Resistant Spanner Machine Screws for Secure Fastening

Why choose spanner machine screws
Spanner machine screws are a practical choice when you need a balance of serviceability and tamper resistance. They are commonly used on access panels, enclosures, public fixtures, restroom partitions, signage, equipment covers, and other installations exposed to the public or frequent handling. Compared with standard machine screws, the spanner drive helps reduce casual tampering and unwanted removal.

Material and performance benefits
Many security spanner machine screws are available in 18-8 stainless steel for dependable corrosion resistance in general-purpose indoor and light outdoor environments. With multiple head styles available, including flat head, pan head, and undercut flat head, you can choose the right fit for flush surfaces, low-profile installations, or general fastening needs.
