! Name !! Description 
|-
| {{code|<barrier>}}
|| Added in [[C++20]]. Provides <code>std::barrier</code>, a reusable thread barrier.
|-
| {{code|<future>}}
|| Added in [[C++11]]. In 32.9.1-1, this section describes components that a C++ program can use to retrieve in one thread the result (value or exception) from a function that has run in the same thread or another thread.
|-
| {{code|<hazard_pointer>}}
|| Added in [[C++26]]. Provides [[Hazard pointer|<code>std::hazard_pointer</code>]].
|-
| {{code|<latch>}}
|| Added in [[C++20]]. Provides <code>std::latch</code>, a single-use thread barrier.
|-
| {{code|<mutex>}}
|| Added in [[C++11]]. In 32.5-1, this section provides mechanisms for mutual exclusion: mutexes, locks, and call once.
|-
| {{code|<rcu>}}
|| Added in [[C++26]]. Provides [[Read-copy-update|read-copy-update mechanisms]].
|-
| {{code|<shared_mutex>}}
|| Added in [[C++14]]. Provides facility for shared mutual exclusion.
|-
| {{code|<semaphore>}}
|| Added in [[C++20]]. Provides [[Semaphore (programming)|semaphore]] that models non-negative resource count.
|-
| {{code|<stop_token>}}
|| Added in [[C++20]]. In 32.3.1-1, this section describes components that can be used to asynchronously request that an operation stops execution in a timely manner, typically because the result is no longer required. Such a request is called a stop request.
|-
| {{code|<thread>}}
