Engineering Fundamentals · Electronics Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A helical ridge on a cylindrical or conical surface used to convert rotational motion into linear motion or to fasten components.
Example in context
“The specification calls for a metric thread with a pitch of 1.5 mm for the bolt.”
“Şartname, cıvata için 1.5 mm adımlı bir metrik diş gerektirir.”
Where engineers use it
In engineering drawings, thread designations appear on bolt, nut, and tapped hole callouts. Engineers specify thread type (metric, unified, etc.), pitch, and class of fit to ensure compatibility and strength in assemblies.
Synonyms: screw thread, threading
Antonyms: groove
In Electronics Engineering
Thread is an IPv6-based, low-power wireless mesh networking protocol designed for smart home and IoT applications, providing secure and reliable communication between devices.
“The smart light bulb joins the Thread network using its built-in radio and securely communicates with the border router.”
