The WebFlux WebClient doesn't use Apache Commons HTTP Client. Although you might be able to implement one solution via custom ClientHttpConnector. The existing ReactorClientHttpConnector is based on the Netty. So, consider to use Netty options to configure the client, e.g.:

ReactorClientHttpConnector connector =
            new ReactorClientHttpConnector(options ->
                    options.option(ChannelOption.SO_TIMEOUT, this.applicationConfig.getHttpClientConnectTimeout()));

or

.onChannelInit(channel -> channel.config().setConnectTimeoutMillis(this.applicationConfig.getHttpClientConnectTimeout()))

UPDATE

We also can use ReadTimeoutHandler:

.onChannelInit(channel -> 
        channel.pipeline()
           .addLast(new ReadTimeoutHandler(this.applicationConfig.getHttpClientConnectTimeout())))
