screw thread
Học thuậtThân thiện
Definition
Noun: A screw thread is the continuous, raised, helical ridge that winds around the cylindrical body of a screw or bolt. This ridge is designed to mate with a corresponding groove in a nut or threaded hole, converting rotational motion into linear motion to fasten or move objects.
Usage
The term "screw thread" refers specifically to the physical helical structure itself. It is a technical term used in engineering, manufacturing, and mechanics. - The mechanic examined the screw thread for any signs of damage or wear. - Precision in cutting the screw thread is crucial for the bolt to fit the nut properly. - The design specifies a fine screw thread for more precise adjustment.
Advanced Usage
- Thread geometry: This refers to the specific shape and measurements of the screw thread, including its pitch, depth, and angle.
- The engineer analyzed the thread geometry to ensure it met the required standards.
- Thread engagement: This describes the amount of contact between the male (screw) and female (nut) threads.
- Sufficient thread engagement is necessary for a strong and secure connection.
