Turvasyillä

Turvasyillä is a Finnish term that translates to "safety nails" or "security screws." It refers to a category of fasteners designed to be tamper-resistant, making them difficult to remove without specialized tools. This increased security is achieved through unique head designs that do not conform to standard screwdriver types.

These specialized screws are commonly employed in applications where preventing unauthorized access or removal is crucial. Examples include public installations, commercial furniture, vandal-prone areas, and sensitive equipment. The primary function of turvasyillä is to deter casual theft and vandalism by making disassembly a significant obstacle.

The variety of turvasyillä is extensive, with each type requiring a specific driver bit. Common examples include pin-in-hex (also known as security hex or security Allen), pin-in-torx (or security star), spanner head (or snake eye), tri-wing, and one-way screws. The latter are designed to be driven in but are nearly impossible to back out without damaging the surrounding material.

The selection of turvasyillä depends on the level of security required and the environmental conditions. Their use contributes to enhanced safety and security in various settings by providing a reliable method of fastening that resists tampering.
