interrupted screw
C2Technical, formal
Definition
Meaning
A mechanical component with a thread (spiral ridge) that has sections removed, allowing it to engage or disengage quickly with a matching part through partial rotation.
In broader use, can refer to any screw mechanism designed for rapid connection or disconnection rather than continuous threading, or metaphorically to any process that is not smooth or continuous.
Linguistics
Semantic Notes
Highly domain-specific; outside of mechanical and firearms engineering contexts, it is rarely encountered. The term describes a physical design feature, not an action.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. The component is identically named. Usage prevalence may vary slightly with specific industries (e.g., historic artillery vs. modern engineering).
Connotations
Technical and precise in both varieties. No additional connotations.
Frequency
Very low frequency in general language. Slightly more likely in British texts concerning historical artillery or vintage engineering.

Usage
Context Usage
Business
Virtually never used.

Used in historical, engineering, or firearms technology papers.
Everyday
Extremely rare; only in detailed discussions of specific mechanical devices.
Technical
Primary context. Describes a specific mechanical fastening or breech-closing mechanism in engineering, artillery, or firearms design.
Examples
By Part of Speech
verb
British English
- This mechanism cannot be 'interrupted screwed'; it is a specific noun.
American English
- You don't 'interrupt a screw'; the term is a compound noun.
adverb
British English
- Not applicable as an adverb.
American English
- Not applicable as an adverb.
adjective
British English
- The interrupted-screw design is classic in British artillery.
American English
- They chose an interrupted-screw breech for the prototype.
Examples
By CEFR Level
- This is a special screw. It has parts missing from its thread.
- The old cannon used an interrupted screw to close the back of the barrel quickly.
- The breech mechanism, based on an interrupted screw, allowed for faster reloading compared to older models.
- The engineer specified an interrupted screw for the coupling, as it permitted rapid engagement with only a quarter turn.
Learning
Memory Aids
Mnemonic
Think of a normal screw thread as a continuous spiral road. An INTERRUPTED screw is like that road with sections missing, so you can drive on or off it quickly with just a partial turn.
Conceptual Metaphor
MECHANISM IS A CONVERSATION (the thread 'speaks' or engages only in sections, not continuously).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'interrupted' as 'прерванный' in an event sense (e.g., a прерванный разговор). Here it is 'прерывистый' or 'секционный'.
- Do not confuse with 'screw' as a verb/vulgarism; this is purely a noun for a hardware component.
Common Mistakes
- Using it as a verb phrase (e.g., 'He interrupted the screw').
- Confusing it with a screw that is broken or malfunctioning.
- Misspelling as 'interupted screw'.

FAQ
Frequently Asked Questions
No. An interrupted screw is a deliberate design feature with sections of the thread removed to allow quick engagement. A broken screw is a damaged component.
It is highly unlikely unless you are specifically discussing mechanical engineering, artillery history, or firearm mechanisms. It is a very technical term.
Its main advantage is allowing rapid connection or disconnection with only a partial rotation (often 90 or 180 degrees), unlike a standard screw which requires many full turns.
No. Here, 'interrupted' is an adjective describing the physical characteristic of the screw's thread (non-continuous). It does not describe an event of interrupting something.
