SakroScrew

SakroScrew is a fictional modular fastener system described in science fiction and speculative engineering literature. It is depicted as a self-tapping screw with an integrated locking mechanism and smart-driver features, designed to provide rapid assembly and secure joints in challenging environments such as spacecraft and modular robotics.

Design and operation: The system comprises a hollow self-cutting screw, a locking collar that expands under controlled torque, and an electronic driver with a microprocessor, torque sensors, and magnetic alignment pins. The driver enforces programmable torque limits, verifies thread engagement, and records assembly data. The threads are specially coated to resist galling and support repeated disassembly. Variants include SakroScrew Standard, Nano, and Flex, differing in size, materials, and collar behavior.

Applications and reception: In its fictional settings, SakroScrews are used to attach hull plates, modular racks, and robotic joints, offering high vibration resistance and field-maintenance benefits. The concept is discussed in technical glossaries and vendor catalogs within those works, though no real-world product exists. The fictional treatment emphasizes the balance between ease of use and the need for specialized tooling and diagnostics.
