yellow group · The short answer
FASTENERS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
A nail is typically hammered into wood or another material to hold pieces in place.
A rivet passes through aligned holes and is deformed to secure two or more components.
A screw turns into material or a threaded opening to secure one component to another.
A staple pierces sheets or other material and bends or grips to keep them together.
Why this group was difficult
- Each word has a familiar non-hardware sense
NAIL can name a body part, RIVET can mean engross, SCREW can be a verb, and STAPLE can mean a basic commodity. - The four devices work in different ways
They are hammered, deformed, threaded or bent, so their shared purpose is clearer than their physical form.
How to spot this pattern next time
When several words name concrete objects, compare what those objects do rather than demanding that they share the same shape or material.
Check whether the candidate set has a standard umbrella term. Here, attachment and joining lead directly to the established noun FASTENERS.
Four useful facts behind the group
- A nail is commonly installed by driving it into material with a hammer.
- A rivet is often chosen when a permanent mechanical joint is required.
- A screw's helical thread converts turning motion into advancing motion.
- A staple can secure paper, fabric, wire mesh and other thin materials.
Questions players ask
The details people search after seeing the group
What connects NAIL, RIVET, SCREW and STAPLE in Connections #1144?
Each is a fastener: a device used to attach, join or secure materials or components.
Why does RIVET belong with NAIL, SCREW and STAPLE?
RIVET names a mechanical fastener that joins components by passing through holes and being deformed to hold them.
What was the main red herring affecting the FASTENERS group?
GEM, NUGGET and PEARL can look like a cluster of small physical valuables, but they do not form a complete group. NAIL, RIVET, SCREW and STAPLE have the exact shared function of fastening materials or components.
